It has 86\ncommits from 10 contributors. Selected changes:\n\n**Fixes**:\n\n- Sort steps in sub-pipelines no longer cause a column lookup error\n  (@lukapeschke, #5066)\n- Dereferencing of sort columns when rendering SQL now done in context of main\n  pipeline (@kgutwin, #5098)\n\n**New Contributors**:\n\n- @lukapeschke, with #5066\n\n## 0.13.2\n\n0.13.2 is a tiny release to fix an issue publishing 0.13.1 to crates.io.\n\n## 0.13.1\n\n0.13.1 is a small release containing a few bug fixes and improvements. Velocity\nhas slowed down a bit in recent months, we're still hoping to finish the new\nresolver and the new formatter in the near future.\n\nIt has 97 commits from 10 contributors. Selected changes:\n\n**Features**:\n\n- Add a option to the experimental documentation generator to output the docs in\n  HTML format. The option is given using the `--format=html` option.\n  (@vanillajonathan, 4791)\n\n- The version of the library is now read from `git describe`. This doesn't\n  affect libraries built on git tags (such as our releases), only those built\n  when developing. When reporting bugs, this helps identify the exact version.\n  (@max-sixty & @m-span, #4804)\n\n**Fixes**:\n\n- Raw strings (`r\"...\"`) are retained through `prqlc fmt` (@max-sixty, #4848)\n\n- Strings containing an odd contiguous number of quotes are now delimited by an\n  odd number of quotes when being formatted. The previous implementation would\n  use an even number, which is invalid PRQL. (@max-sixty, #4850)\n\n- A few more keywords are quoted, such as `user`, which is a reserved keyword in\n  PostgreSQL. (@max-sixty)\n\n## 0.13.0 — 2024-07-25\n\n0.13.0 brings a new debug logging framework, a big refactor of the parser, a new\nhighlighter, an `**` operator for exponentiation, a few bug fixes, and lots of\nother changes. It has 153 commits from 11 contributors.\n\nOur work continues on rewriting the resolver and completing `prqlc fmt`.\n\nSelected changes:\n\n**Language**:\n\n- Parentheses are always required around pipelines, even within tuples. For\n  example:\n\n  ```prql no-eval\n  from artists\n  # These parentheses are now required\n  derive {a=(b | math.abs)}\n  # No change — doesn't affect expressions or function calls without pipelines\n  derive {x = 3 + 4}\n  ```\n\n  This is a small breaking change. The new behavior matches the existing\n  documentation. (@max-sixty, #4775)\n\n- A new `**` operator for exponentiation. (@aljazerzen & @max-sixty, #4125)\n\n**Features**:\n\n- `prqlc compile --debug-log=log.html` will generate an HTML file with a\n  detailed log of the compilation process. (@aljazerzen, #4646)\n- Added `prqlc debug json-schema` command to auto-generate JSON Schema\n  representations of commonly exposed IR types such as PL and RQ. (@kgutwin,\n  #4698)\n- Add documentation comments to the output of the documentation generator.\n  (@vanillajonathan, #4729)\n- Add CLI syntax highlighting to `prqlc`. You can try it as\n  `prqlc experimental highlight example.prql`. (@vanillajonathan, #4755)\n\n**Fixes**:\n\n- Using `in` with an empty array pattern (e.g. `expr | in []`) will now output a\n  constant `false` condition instead of an `expr IN ()`, which is syntactically\n  invalid in some SQL dialects (@Globidev, #4598)\n\n**Integrations**:\n\n- The Snap package previously released on the edge channel is now released on\n  the stable channel. (@vanillajonathan, #4784)\n\n**Internal changes**:\n\n- Major reorganization of `prqlc-parser` — `prqlc-ast` is merged into\n  `prqlc-parser`, and `prqlc-parser`'s files are rearranged, including its\n  exports. This is part of an effort to modularize the compiler by stage,\n  reducing the amount of context that's required to understand a single stage.\n  There will likely be some further changes (more detail in the PR description).\n  (@m-span, #4634)\n  - This is a breaking change for any libraries that depend on `prqlc-parser`\n    (which should be fairly rare).\n\n- Renamed `prql-compiler-macros` to `prqlc-macros` for consistency with other\n  crates (@max-sixty, #4565)\n\n- `prql-compiler`, the old name for `prqlc`, is removed as a facade to `prqlc`.\n  It had been deprecated for a few versions and will no longer be updated.\n  (@max-sixty)\n\n- New benchmarks (@max-sixty, #4654)\n\n**New Contributors**:\n\n- @Globidev, with #4598\n\n## 0.12.2 — 2024-06-10\n\n0.12.2 is a very small release which renames `prql-js` to `prqlc-js` to match\nour standard naming scheme. Within node the package is imported as `prqlc`.\n\nIt also fixes a mistake in the `prqlc-python` release pipeline.\n\n## 0.12.1 — 2024-06-09\n\n0.12.1 is a tiny hotfix release which fixes how intra-prql crate dependencies\nwere specified.\n\n## 0.12.0 — 2024-06-08\n\n0.12.0 contains a few months of smaller features. Our focus has been on\nrewriting the resolver, an effort that is still ongoing.\n\nIt has 239 commits from 12 contributors. Selected changes (most are not listed\nhere, possibly we should be more conscientious about adding them...):\n\n**Features**:\n\n- Add `prqlc lex` command to the CLI (@max-sixty)\n- Add `prqlc debug lineage` command to the CLI, creating an expression lineage\n  graph from a query (@kgutwin, #4533)\n- Initial implementation of an experimental documentation generator that\n  generates Markdown documentation from `.prql` files. (@vanillajonathan,\n  #4152).\n- Join's `side` parameter can take a reference that resolves to a literal (note:\n  this is an experimental feature which may change in the future) (@kgutwin,\n  #4499)\n\n**Fixes**:\n\n- Support expressions on left hand side of `std.in` operator. (@kgutwin, #4498)\n- Prevent panic for `from {}` and `std` (@m-span, #4538)\n\n**Web**:\n\n- The `browser` dist files are now built with `wasm-pack`'s `web` target. As a\n  result, they should be usable as ES Modules, through JS CDNs, and for example\n  with Observable Framework (@srenatus, #4274).\n\n**Integrations**:\n\n- The syntax highlighter package for Sublime Text is now\n  [published](https://packagecontrol.io/packages/PRQL) (@vanillajonathan).\n- The\n  [VSCode Great Icons](https://marketplace.visualstudio.com/items?itemName=emmanuelbeziat.vscode-great-icons)\n  icon pack extension shows a database icon for `.prql` files. (@EmmanuelBeziat)\n- [Tokei](https://github.com/XAMPPRocky/tokei), a source lines of code counter\n  now has support for `.prql` files. (@vanillajonathan)\n- Add syntax highlight file for the [micro](https://micro-editor.github.io/)\n  text editor. (@vanillajonathan)\n\n**New Contributors**:\n\n- @srenatus, with #4274\n- @jacquayj, with #4332\n- @pdelewski, with #4337\n- @m-span, with #4422\n- @kgutwin, with #4498\n\n## 0.11.4 — 2024-02-25\n\n0.11.4 is a hotfix release, fixing a CI issue that caused the CLI binaries to be\nbuilt without the `cli` feature.\n\n## 0.11.3 — 2024-02-10\n\n0.11.3 is a very small release, mostly a rename of the Python bindings.\n\nThe release has 13 commits from 4 contributors.\n\n**Internal changes**:\n\n- As part of making our names more consistent, the Python bindings are renamed.\n  `prql-python` becomes a package published and importable as `prqlc`. The\n  internal Rust crate is named `prqlc-python`.\n\n## 0.11.2 — 2024-02-07\n\n0.11.2 contains lots of internal changes, lots of syntax highlighting, and the\nbeginning of `lutra`, a query runner.\n\nThis release has 122 commits from 9 contributors. Selected changes:\n\n**Features**:\n\n- Initial implementation of `lutra`, a query runner. (@aljazerzen, #4182, #4174,\n  #4134)\n- `prqlc fmt` works on projects with multiple files.

(@vanillajonathan, #4127)\n- [sloc](https://github.com/flosse/sloc), a source lines of code counter now has\n  support for `.prql` files. (@vanillajonathan)\n\n**Internal changes**:\n\n- `prql-compiler` has been renamed to `prqlc`, and we've established a more\n  consistent naming scheme. The existing crate will still be published,\n  re-exporting `prqlc`, so no dependencies will break. A future version will add\n  a deprecation warning.\n- The `prqlc-clib` crate was renamed to `prqlc-c`, and associated artifacts were\n  renamed. We're trying to make names consistent (ideally for the final time!),\n  and have a plan to rename some other bindings. (@max-sixty, #4077)\n- Add lots of whitespace items to the lexer, in preparation for the completion\n  of `prqlc fmt` (@max-sixty, #4109, #4105)\n- Table declarations (@aljazerzen, #4126)\n\n**New Contributors**:\n\n- @kaspermarstal, with #4124\n\n## 0.11.1 — 2023-12-26\n\n0.11.1 fixes a couple of small bugs; it comes a few days after 0.11.\n\nThis release has 16 commits from 6 contributors.

The old `prql_version` function is deprecated and\n  will be removed in the future release. (@eitsupi, #4006)\n\n**Fixes**:\n\n- Do not compile to `DISTINCT ON` when `take n` is used with `group` for the\n  targets `clickhouse`, `duckdb` and `postgres`. (@PrettyWood, #3988)\n- Fix `take` n rows for `mssql` dialect by switching from TOP to FETCH\n  (@PrettyWood, #3994)\n\n## 0.11.0 — 2023-12-19\n\n0.11.0 introduces new `date`, `text` & `math` modules with lots of standard\nfunctions, including a new `date.to_text` function.

The\nrelease has 77 commits from 8 contributors. Selected changes are below.\n\nLook out for some conference talks coming up over the next few weeks, including\n[QCon SF on Oct 2](https://qconsf.com/presentation/oct2023/prql-simple-powerful-pipelined-sql-replacement)\nand\n[date2day on Oct 12](https://www.data2day.de/veranstaltung-21353-0-prql-a-modern-language-for-data-transformation.html).\n\n**Language**:\n\n- A new line-wrapping character, for lines that are long and we want to break up\n  into multiple physical lines. This is slightly different from from many\n  languages — it's on the subsequent line:\n\n  ```prql no-eval\n  from artists\n  select is_europe =\n  \\ country == \"DE\"\n  \\ || country == \"FR\"\n  \\ || country == \"ES\"\n  ```\n\n  This allows for easily commenting out physical lines while maintaining a\n  correct logical line; for example:\n\n  ```diff\n  from artists\n  select is_europe =\n  \\ country == \"DE\"\n  \\ || country == \"FR\"\n  \\ || country == \"FR\"\n  -\\ || country == \"ES\"\n  +#\\ || country == \"ES\"\n  ```\n\n  (@max-sixty, #3408)\n\n**Fixes**:\n\n- Fix stack overflow on very long queries in Windows debug builds (@max-sixty,\n  #2908)\n\n- Fix panic when unresolved lineage appears in group or window (@davidot, #3266)\n\n- Fix a corner-case in handling precedence, and remove unneeded parentheses in\n  some outputs (@max-sixty, #3472)\n\n**Web**:\n\n- Compiler panics are now printed to the console (@max-sixty, #3446)\n\n**Integrations**:\n\n- [Ace](https://ace.c9.io/), the JavaScript code editor now has syntax\n  highlighting for PRQL. (@vanillajonathan, #3493)\n\n**Internal changes**:\n\n- Simplify & speed up lexer (@max-sixty, #3426, #3418)\n\n**New Contributors**:\n\n- @davidot, with #3450\n\n## 0.9.4 — 2023-08-24\n\n0.9.4 is a small release with some improvements and bug fixes in the compiler\nand `prqlc`. And, the documentation and CI are continually being improved.\n\nThis release has 110 commits from 9 contributors. Selected changes:\n\n**Features**:\n\n- Strings can be delimited with any odd number of quote characters. The logic\n  for lexing quotes is now simpler and slightly faster. Escapes in\n  single-quote-delimited strings escape single-quotes rather than double-quotes.\n  (@max-sixty, #3274)\n\n**Fixes**:\n\n- S-strings within double braces now parse correctly (@max-sixty, #3265)\n\n**Documentation**:\n\n- New docs for strings (@max-sixty, #3281)\n\n**Web**:\n\n- Improve syntax highlighting for numbers in the book & website (@max-sixty,\n  #3261)\n- Add ClickHouse integration to docs (@max-sixty, #3251)\n\n**Integrations**:\n\n- `prqlc` no longer displays a prompt when piping a query into its stdin\n  (@max-sixty, #3248).\n- Add a minimal example for use `prql-lib` with Zig (@vanillajonathan, #3372)\n\n**Internal changes**:\n\n- Overhaul our CI to run a cohesive set of tests depending on the specific\n  changes in the PR, and elide all others. This cuts CI latency to less than\n  three minutes for most changes, and enables GitHub's auto-merge to wait for\n  all relevant tests. It also reduces the CI time on merging to main, by moving\n  some tests to only run on specific path changes or on our nightly run.\n\n  We now have one label we can add to PRs to run more tests — `pr-nightly`.\n  (@max-sixty, #3317 & others).\n\n- Auto-merge PRs for backports or pre-commit updates (@max-sixty, #3246)\n- Add a workflow to create an issue when the scheduled nightly workflow fails\n  (@max-sixty, #3304)\n\n**New Contributors**:\n\n- @FinnRG, with #3292\n- @sitiom, with #3353\n\n## 0.9.3 — 2023-08-02\n\n0.9.3 is a small release, with mostly documentation, internal, and CI changes.\n\nThis release has 85 commits from 10 contributors.\n\nWe'd like to welcome @not-my-profile as someone who has helped with lots of\ninternal refactoring in the past couple of weeks.\n\n**New Contributors**:\n\n- @vthriller, with #3171\n- @postmeback, with #3216\n\n## 0.9.2 — 2023-07-25\n\n0.9.2 is a hotfix release to fix an issue in the 0.9.0 & 0.9.1 release\npipelines.\n\n## 0.9.1 — 2023-07-25\n\n0.9.1 is a hotfix release to fix an issue in the 0.9.0 release pipeline.\n\n## 0.9.0 — 2023-07-24\n\n0.9.0 is probably PRQL's biggest ever release. We have dialect-specific\nstandard-libraries, a regex operator, an initial implementation of multiple-file\nprojects & modules, lots of bug fixes, and many many internal changes.\n\nWe've made a few backward incompatible syntax changes. Most queries will work\nwith a simple find/replace; see below for details.\n\nThe release has 421 commits from 12 contributors.\n\nA small selection of the changes:\n\n**Language**:\n\n- The major breaking change is a new syntax for lists, which have been renamed\n  to _tuples_, and are now represented with braces `{}` rather than brackets\n  `[]`.\n\n  To convert previous PRQL queries to this new syntax simply change `[ ... ]` to\n  `{ ... }`.\n\n  We made the syntax change to incorporate arrays. Almost every major language\n  uses `[]` for arrays. We are adopting that convention — arrays use `[]`,\n  tuples will use `{}`. (Though we recognize that `{}` for tuples is also rare\n  (Hi, Erlang!), but didn't want to further load parentheses with meaning.)\n\n  Arrays are conceptually similar to columns — their elements have a single\n  type. Array syntax can't contain assignments.\n\n  As part of this, we've also formalized tuples as containing both individual\n  items (`select {foo, baz}`), and assignments (`select {foo=bar, baz=fuz}`).\n\n- Some significant changes regarding SQL dialects:\n  - Operators and functions can be defined on per-dialect basis. (@aljazerzen,\n    #2681)\n  - _Breaking_: The `sql.duckdb` target supports DuckDB 0.8 (@eitsupi, #2810).\n  - _Breaking_: The `sql.hive` target is removed (@eitsupi, #2837).\n\n- New arithmetic operators. These compile to different function or operator\n  depending on the target.\n  - _Breaking_: Operator `/` now always performs floating division (@aljazerzen,\n    #2684). See the\n    [Division docs](https://prql-lang.org/book/reference/syntax/operators.html#division-and-integer-division)\n    for details.\n\n  - Truncated integer division operator `//` (@aljazerzen, #2684). See the\n    [Division docs](https://prql-lang.org/book/reference/syntax/operators.html#division-and-integer-division)\n    for details.\n\n  - Regex search operator `~=` (@max-sixty, #2458). An example:\n\n    ```prql no-eval\n    from tracks\n    filter (name ~= \"Love\")\n    ```\n\n    ...compiles to;\n\n    ```sql\n    SELECT\n      *\n    FROM\n      tracks\n    WHERE\n      REGEXP(name, 'Love')\n    ```\n\n    ...though the exact form differs by dialect; see the\n    [Regex docs](https://prql-lang.org/book/reference/syntax/operators.html#regex)\n    for more details.\n\n- New aggregation functions: `every`, `any`, `average`, and `concat_array`.\n  _Breaking:_ Remove `avg` in favor of `average`.\n\n- _Breaking:_ We've changed our function declaration syntax to match other\n  declarations. Functions were one of the first language constructs in PRQL, and\n  since then we've added normal declarations there's no compelling reason for\n  functions to be different.\n\n  ```prql no-eval\n  let add = a b -> a + b\n  ```\n\n  Previously, this was:\n\n  ```prql no-eval\n  func add a b -> a + b\n  ```\n\n- Experimental modules, which allow importing declarations from other files.\n  Docs are forthcoming.\n\n- Relation literals create a relation (a \"table\") as an _array_ of _tuples_.\n  This example demonstrates the new syntax for arrays `[]` and tuples `{}`.\n  (@aljazerzen, #2605)\n\n  ```prql no-eval\n  from [{a=5, b=false}, {a=6, b=true}]\n  filter b == true\n  select a\n  ```\n\n- `this` can be used to refer to the current pipeline, for situations where\n  plain column name would be ambiguous:\n\n  ```prql no-eval\n  from x\n  derive sum = my_column\n  select this.sum   # does not conflict with `std.sum`\n  ```\n\n  Within a `join` transform, there is also a reference to the right relation:\n  `that`.\n\n- _Breaking:_ functions `count`, `rank` and `row_number` now require an argument\n  of the array to operate on. In most cases you can directly replace `count`\n  with `count this`. The `non_null` argument of `count` has been removed.\n\n**Features**:\n\n- We've changed how we handle colors.\n\n  `Options::color` is deprecated and has no effect. Code which consumes\n  `prql_compiler::compile` should instead accept the output with colors and use\n  a library such as `anstream` to handle the presentation of colors. To ensure\n  minimal disruption, `prql_compiler` will currently strip color codes when a\n  standard environment variable such as `CLI_COLOR=0` is set or when it detects\n  `stderr` is not a TTY.\n\n  We now use the [`anstream`](https://github.com/rust-cli/anstyle) library in\n  `prqlc` & `prql-compiler`.\n\n  (@max-sixty, #2773)\n\n- `prqlc` can now show backtraces when the standard backtrace env var\n  (`RUST_BACKTRACE`) is active. (@max-sixty, #2751)\n\n**Fixes**:\n\n- Numbers expressed with scientific notation — `1e9` — are now handled correctly\n  by the compiler (@max-sixty, #2865).\n\n**Integrations**:\n\n- prql-python now provides type hints (@philpep, #2912)\n\n**Internal changes**:\n\n- Annotations in PRQL. These have limited support but are currently used to\n  specify binding strengths. They're modeled after Rust's annotations, but with\n  `@` syntax, more similar to traditional decorators. (#2729)\n\n  ```prql no-eval\n  @{binding_strength=11}\n  let mod = l r -> s\"{l} % {r}\"\n  ```\n\n- Remove BigQuery's special handling of quoted identifiers, now that our module\n  system handles its semantics (@max-sixty, #2609).\n\n- ClickHouse is tested in CI (@eitsupi, #2815).\n\n**New Contributors**:\n\n- @maxmcd, with #2533\n- @khoa165, with #2876\n- @philpep, with #2912\n- @not-my-profile, with #2971\n\n## 0.8.1 — 2023-04-29\n\n0.8.1 is a small release with a new `list-targets` command in `prqlc`, some\ndocumentation improvements, and some internal improvements.\n\nThis release has 41 commits from 8 contributors.\n\nFrom the broader perspective of the project, we're increasing the relative\nprioritization of it being easy for folks to actually use PRQL — either with\nexisting tools, or a tool we'd build. We'll be thinking about & discussing the\nbest way to do that over the next few weeks.\n\n## 0.8.0 — 2023-04-14\n\n0.8.0 renames the `and` & `or` operators to `&&` & `||` respectively,\nreorganizes the Syntax section in the book, and introduces `read_parquet` &\n`read_csv` functions for reading files with DuckDB.\n\nThis release has 38 commits from 8 contributors. Selected changes:\n\n**Features**:\n\n- Rename `and` to `&&` and `or` to `||`. Operators which are symbols are now\n  consistently infix, while \"words\" are now consistently functions (@aljazerzen,\n  #2422).\n\n- New functions `read_parquet` and `read_csv`, which mirror the DuckDB\n  functions, instructing the database to read from files (@max-sixty, #2409).\n\n## 0.7.1 — 2023-04-03\n\n0.7.1 is a hotfix release to fix `prql-js`'s `npm install` behavior when being\ninstalled as a dependency.\n\nThis release has 17 commits from 4 contributors.\n\n## 0.7.0 — 2023-04-01\n\n0.7.0 is a fairly small release in terms of new features, with lots of internal\nimprovements, such as integration tests with a whole range of DBs, a blog post\non Pi day, RFCs for a type system, and more robust language bindings.\n\nThere's a very small breaking change to the Rust API, hence the minor version\nbump.\n\nHere's our April 2023 Update, from our\n[Readme](https://github.com/PRQL/prql/blob/main/README.md):\n\n> ### April 2023 update\n>\n> PRQL is being actively developed by a growing community. It's ready to use by\n> the intrepid, either as part of one of our supported extensions, or within\n> your own tools, using one of our supported language bindings.\n>\n> PRQL still has some minor bugs and some missing features, and probably is only\n> ready to be rolled out to non-technical teams for fairly simple queries.\n>\n> Here's our current [Roadmap](https://prql-lang.org/roadmap/) and our\n> [Milestones.](https://github.com/PRQL/prql/milestones)\n>\n> Our immediate focus for the code is on:\n>\n> - Building out the next few big features, including\n>   [types](https://github.com/PRQL/prql/pull/1964) and\n>   [modules](https://github.com/PRQL/prql/pull/2129).\n> - Ensuring our supported features feel extremely robust; resolving any\n>   [priority bugs](https://github.com/PRQL/prql/issues?q=is%3Aissue+is%3Aopen+label%3Abug+label%3Apriority).\n>\n> We're also spending time thinking about:\n>\n> - Making it really easy to start using PRQL. We're doing that by building\n>   integrations with tools that folks already use; for example our VS Code\n>   extension & Jupyter integration. If there are tools you're familiar with\n>   that you think would be open to integrating with PRQL, please let us know in\n>   an issue.\n> - Making it easier to contribute to the compiler. We have a wide group of\n>   contributors to the project, but contributions to the compiler itself are\n>   quite concentrated. We're keen to expand this;\n>   [#1840](https://github.com/PRQL/prql/issues/1840) for feedback.\n\n---\n\nThe release has 131 commits from 10 contributors. Particular credit goes to to\n@eitsupi & @jelenkee, who have made significant contributions, and\n@vanillajonathan, whose prolific contribution include our growing language\nbindings.\n\nA small selection of the changes:\n\n**Features**:\n\n- `prqlc compile` adds `--color` & `--include-signature-comment` options.\n  (@max-sixty, #2267)\n\n**Web**:\n\n- Added the PRQL snippets from the book to the\n  [Playground](https://prql-lang.org/playground/) (@jelenkee, #2197)\n\n**Internal changes**:\n\n- _Breaking_: The `compile` function's `Options` now includes a `color` member,\n  which determines whether error messages use ANSI color codes. This is\n  technically a breaking change to the API. (@max-sixty, #2251)\n- The `Error` struct now exposes the `MessageKind` enum. (@vanillajonathan,\n  #2307)\n- Integration tests run in CI with DuckDB, SQLite, PostgreSQL, MySQL and SQL\n  Server (@jelenkee, #2286)\n\n**New Contributors**:\n\n- @k-nut, with #2294\n\n## 0.6.1 — 2023-03-12\n\n0.6.1 is a small release containing an internal refactoring and improved\nbindings for C, PHP & .NET.\n\nThis release has 54 commits from 6 contributors. Selected changes:\n\n**Fixes**:\n\n- No longer incorrectly compile to `DISTINCT` when a `take 1` refers to a\n  different set of columns than are in the `group`. (@max-sixty, with thanks to\n  @cottrell, #2109)\n- The version specification of the dependency Chumsky was bumped from `0.9.0` to\n  `0.9.2`. `0.9.0` has a bug that causes an infinite loop. (@eitsupi, #2110)\n\n**Documentation**:\n\n- Add a policy for which bindings are supported / unsupported / nascent. See\n  <https://prql-lang.org/book/project/bindings/index.html> for more details\n  (@max-sixty, #2062) (@max-sixty, #2062)\n\n**Integrations**:\n\n- [prql-lib] Added C++ header file. (@vanillajonathan, #2126)\n\n**Internal changes**:\n\n- Many of the items that were in the root of the repo have been aggregated into\n  `web` & `bindings`, simplifying the repo's structure. There's also `grammars`\n  & `packages` (@max-sixty, #2135, #2117, #2121).\n\n## 0.6.0 — 2023-03-08\n\n0.6.0 introduces a rewritten parser, giving us the ability to dramatically\nimprove error messages, renames `switch` to `case` and includes lots of minor\nimprovements and fixes. It also introduces `loop`, which compiles to\n`WITH RECURSIVE`, as a highly experimental feature.\n\nThere are a few cases of breaking changes, including switching `switch` to\n`case`, in case that's confusing. There are also some minor parsing changes\noutlined below.\n\nThis release has 108 commits from 11 contributors. Selected changes:\n\n**Features**:\n\n- Add a (highly experimental) `loop` language feature, which translates to\n  `WITH RECURSIVE`. We expect changes and refinements in upcoming releases.\n  (#1642, @aljazerzen)\n- Rename the experimental `switch` function to `case` given it more closely\n  matches the traditional semantics of `case`. (@max-sixty, #2036)\n- Change the `case` syntax to use `=>` instead of `->` to distinguish it from\n  function syntax.\n- Convert parser from pest to Chumsky (@aljazerzen, #1818)\n  - Improved error messages, and the potential to make even better in the\n    future. Many of these improvements come from error recovery.\n  - String escapes (`\\n \\t`).\n  - Raw strings that don't escape backslashes.\n  - String interpolations can only contain identifiers and not any expression.\n  - Operator associativity has been changed from right-to-left to left-to-right\n    to be more similar to other conventional languages.\n  - `and` now has a higher precedence than `or` (of same reason as the previous\n    point).\n  - Dates, times and timestamps have stricter parsing rules.\n  - `let`, `func`, `prql`, `case` are now treated as keywords.\n  - Float literals without fraction part are not allowed anymore (`1.`).\n- Add a `--format` option to `prqlc parse` which can return the AST in YAML\n  (@max-sixty, #1962)\n- Add a new subcommand `prqlc jinja`. (@aljazerzen, #1722)\n- _Breaking_: prql-compiler no longer passes text containing `{{` & `}}` through\n  to the output. (@aljazerzen, #1722)\n\n  For example, the following PRQL query\n\n  ```prql no-eval\n  from {{foo}}\n  ```\n\n  was compiled to the following SQL previously, but now it raises an error.\n\n  ```sql\n  SELECT\n    *\n  FROM\n    {{ foo }}\n  ```\n\n  This pass-through feature existed for integration with dbt.\n\n  We're again considering how to best integrate with dbt, and this change is\n  based on the idea that the jinja macro should run before the PRQL compiler.\n\n  If you're interested in dbt integration, subscribe or 👍 to\n  <https://github.com/dbt-labs/dbt-core/pull/5982>.\n\n- A new compile target `\"sql.any\"`. When `\"sql.any\"` is used as the target of\n  the compile function's option, the target contained in the query header will\n  be used. (@aljazerzen, #1995)\n- Support for SQL parameters with similar syntax (#1957, @aljazerzen)\n- Allow `:` to be elided in timezones, such as `0800` in\n  `@2020-01-01T13:19:55-0800` (@max-sixty, #1991).\n- Add `std.upper` and `std.lower` functions for changing string casing\n  (@Jelenkee, #2019).\n\n**Fixes**:\n\n- `prqlc compile` returns a non-zero exit code for invalid queries. (@max-sixty,\n  #1924)\n- Identifiers can contain any alphabetic unicode characters (@max-sixty, #2003)\n\n**Documentation**:\n\n- Operator precedence (@aljazerzen, #1818)\n- Error messages for invalid queries are displayed in the book (@max-sixty,\n  #2015)\n\n**Integrations**:\n\n- [prql-php] Added PHP bindings. (@vanillajonathan, #1860)\n- [prql-dotnet] Added .NET bindings. (@vanillajonathan, #1917)\n- [prql-lib] Added C header file. (@vanillajonathan, #1879)\n- Added a workflow building a `.deb` on each release. (Note that it's not yet\n  published on each release). (@vanillajonathan, #1883)\n- Added a workflow building a `.rpm` on each release. (Note that it's not yet\n  published on each release). (@vanillajonathan, #1918)\n- Added a workflow building a Snap package on each release. (@vanillajonathan,\n  #1881)\n\n**Internal changes**:\n\n- Test that the output of our nascent autoformatter can be successfully compiled\n  into SQL. Failing examples are now clearly labeled. (@max-sixty, #2016)\n- Definition files have been added to configure\n  [Dev Containers](https://containers.dev/) for Rust development environment.\n  (@eitsupi, #1893, #2025, #2028)\n\n**New Contributors**:\n\n- @linux-china, with #1971\n- @Jelenkee, with #2019\n\n## 0.5.2 — 2023-02-18\n\n0.5.2 is a tiny release to fix an build issue in yesterday's `prql-js` 0.5.1\nrelease.\n\nThis release has 7 commits from 2 contributors.\n\n**New Contributors**:\n\n- @matthias-Q, with #1873\n\n## 0.5.1 — 2023-02-17\n\n0.5.1 contains a few fixes, and another change to how bindings handle default\ntarget / dialects.\n\nThis release has 53 commits from 7 contributors. Selected changes:\n\n**Fixes**:\n\n- Delegate dividing literal integers to the DB. Previously integer division was\n  executed during PRQL compilation, which could be confusing given that behavior\n  is different across DBs. Other arithmetic operations are still executed during\n  compilation. (@max-sixty, #1747)\n\n**Documentation**:\n\n- Add docs on the `from_text` transform (@max-sixty, #1756)\n\n**Integrations**:\n\n- [prql-js] Default compile target changed from `Sql(Generic)` to `Sql(None)`.\n  (@eitsupi, #1856)\n- [prql-python] Compilation options can now be specified from Python. (@eitsupi,\n  #1807)\n- [prql-python] Default compile target changed from `Sql(Generic)` to\n  `Sql(None)`. (@eitsupi, #1861)\n\n**New Contributors**:\n\n- @vanillajonathan, with #1766\n\n## 0.5.0 — 2023-02-08\n\n0.5.0 contains a few fixes, some improvements to bindings, lots of docs\nimprovements, and some work on forthcoming features. It contains one breaking\nchange in the compiler's `Options` interface.\n\nThis release has 74 commits from 12 contributors. Selected changes:\n\n**Features**:\n\n- Change public API to use target instead of dialect in preparation for feature\n  work (@aljazerzen, #1684)\n\n- `prqlc watch` command which watches filesystem for changes and compiles .prql\n  files to .sql (@aljazerzen, #1708)\n\n**Fixes**:\n\n- Support double brackets in s-strings which aren't symmetric (@max-sixty,\n  #1650)\n- Support Postgres's Interval syntax (@max-sixty, #1649)\n- Fixed tests for `prql-elixir` with macOS (@kasvith, #1707)\n\n**Documentation**:\n\n- Add a documentation test for prql-compiler, update prql-compiler README, and\n  include the README in the prql book section for Rust bindings. The code\n  examples in the README are included and tested as doctests in the\n  prql-compiler (@nkicg6, #1679)\n\n**Internal changes**:\n\n- Add tests for all PRQL website examples to prql-python to ensure compiled\n  results match expected SQL (@nkicg6, #1719)\n\n**New Contributors**:\n\n- @ruslandoga, with #1628\n- @RalfNorthman, with #1632\n- @nicot, with #1662\n\n## 0.4.2 — 2023-01-25\n\n**Features**:\n\n- New `from_text format-arg string-arg` function that supports JSON and CSV\n  formats. _format-arg_ can be `format:csv` or `format:json`. _string-arg_ can\n  be a string in any format. (@aljazerzen & @snth, #1514)\n\n  ```prql no-eval\n  from_text format:csv \"\"\"\n  a,b,c\n  1,2,3\n  4,5,6\n  \"\"\"\n  ```\n\n  ```prql no-eval\n  from_text format:json '''\n      [{\"a\": 1, \"b\": \"x\", \"c\": false }, {\"a\": 4, \"b\": \"y\", \"c\": null }]\n  '''\n  ```\n\n  ```prql no-eval\n  from_text format:json '''{\n      \"columns\": [\"a\", \"b\", \"c\"],\n      \"data\": [\n          [1, \"x\", false],\n          [4, \"y\", null]\n      ]\n  }'''\n  ```\n\n  For now, the argument is limited to string constants.\n\n**Fixes**\n\n- Export constructor for SQLCompileOptions (@bcho, #1621)\n- Remove backticks in count_distinct (@aljazerzen, #1611)\n\n**New Contributors**\n\n- @1Kinoti, with #1596\n- @veenaamb, with #1614\n\n## 0.4.1 — 2023-01-18\n\n0.4.1 comes a few days after 0.4.0, with a couple of features and the release of\n`prqlc`, the CLI crate.\n\n0.4.1 has 35 commits from 6 contributors.\n\n**Features**:\n\n- Inferred column names include the relation name (@aljazerzen, #1550):\n\n  ```prql no-eval\n  from albums\n  select title # name used to be inferred as title only\n  select albums.title # so using albums was not possible here\n  ```\n\n- Quoted identifiers such as `dir/*.parquet` are passed through to SQL.\n  (@max-sixty, #1516).\n\n- The CLI is installed with `cargo install prqlc`. The binary was renamed in\n  0.4.0 but required an additional `--features` flag, which has been removed in\n  favor of this new crate (@max-sixty & @aljazerzen, #1549).\n\n**New Contributors**:\n\n- @fool1280, with #1554\n- @nkicg6, with #1567\n\n## 0.4.0 — 2023-01-15\n\n0.4.0 brings lots of new features including `case`, `select ![]` and numbers\nwith underscores. We have initial (unpublished) bindings to Elixir. And there's\nthe usual improvements to fixes & documentation (only a minority are listed\nbelow in this release).\n\n0.4.0 also has some breaking changes: `table` is `let`, `dialect` is renamed to\n`target`, and the compiler's API has changed. Full details below.\n\n**Features**:\n\n- Defining a temporary table is now expressed as `let` rather than `table`\n  (@aljazerzen, #1315). See the\n  [tables docs](https://prql-lang.org/book/reference/declarations/variables.html)\n  for details.\n\n- _Experimental:_ The\n  [`case`](https://prql-lang.org/book/reference/syntax/case.html) function sets\n  a variable to a value based on one of several expressions (@aljazerzen,\n  #1278).\n\n  ```prql no-eval\n  derive var = case [\n    score <= 10 -> \"low\",\n    score <= 30 -> \"medium\",\n    score <= 70 -> \"high\",\n    true -> \"very high\",\n  ]\n  ```\n\n  ...compiles to:\n\n  ```sql\n  SELECT\n    *,\n    CASE\n      WHEN score <= 10 THEN 'low'\n      WHEN score <= 30 THEN 'medium'\n      WHEN score <= 70 THEN 'high'\n      ELSE 'very high'\n    END AS var\n  FROM\n    bar\n  ```\n\n  Check out the\n  [`case` docs](https://prql-lang.org/book/reference/syntax/case.html) for more\n  details.\n\n- _Experimental:_ Columns can be excluded by name with `select` (@aljazerzen,\n  #1329)\n\n  ```prql no-eval\n  from albums\n  select ![title, composer]\n  ```\n\n- _Experimental:_ `append` transform, equivalent to `UNION ALL` in SQL.\n  (@aljazerzen, #894)\n\n  ```prql no-eval\n  from employees\n  append managers\n  ```\n\n  Check out the\n  [`append` docs](https://prql-lang.org/book/reference/stdlib/transforms/append.html)\n  for more details.\n\n- Numbers can contain underscores, which can make reading long numbers easier\n  (@max-sixty, #1467):\n\n  ```prql no-eval\n  from numbers\n  select {\n      small = 1.000_000_1,\n      big = 5_000_000,\n  }\n  ```\n\n- The SQL output contains a comment with the PRQL compiler version (@aljazerzen,\n  #1322)\n- `dialect` is renamed to `target`, and its values are prefixed with `sql.`\n  (@max-sixty, #1388); for example:\n\n  ```prql no-eval\n  prql target:sql.bigquery  # previously was `dialect:bigquery`\n\n  from employees\n  ```\n\n  This gives us the flexibility to target other languages than SQL in the long\n  term.\n\n- Tables definitions can contain a bare s-string (@max-sixty, #1422), which\n  enables us to include a full CTE of SQL, for example:\n\n  ```prql no-eval\n  let grouping = s\"\"\"\n    SELECT SUM(a)\n    FROM tbl\n    GROUP BY\n      GROUPING SETS\n      ((b, c, d), (d), (b, d))\n  \"\"\"\n  ```\n\n- Ranges supplied to `in` can be half-open (@aljazerzen, #1330).\n\n- The crate's external API has changed to allow for compiling to intermediate\n  representation. This also affects bindings. See\n  [`prql-compiler` docs](https://docs.rs/prql-compiler/latest/prql_compiler/)\n  for more details.\n\n**Fixes**:\n\n[This release, the changelog only contains a subset of fixes]\n\n- Allow interpolations in table s-strings (@aljazerzen, #1337)\n\n**Documentation**:\n\n[This release, the changelog only contains a subset of documentation\nimprovements]\n\n- Add docs on aliases in\n  [Select](https://prql-lang.org/book/reference/stdlib/transforms/select.html)\n- Add JS template literal and multiline example (@BCsabaEngine, #1432)\n- JS template literal and multiline example (@BCsabaEngine, #1432)\n- Improve prql-compiler docs & examples (@aljazerzen, #1515)\n- Fix string highlighting in book (@max-sixty, #1264)\n\n**Web**:\n\n- The playground allows querying some sample data. As before, the result updates\n  on every keystroke. (@aljazerzen, #1305)\n\n**Integrations**:\n\n[This release, the changelog only contains a subset of integration improvements]\n\n- Added Elixir integration exposing PRQL functions as NIFs (#1500, @kasvith)\n- Exposed Elixir flavor with exceptions (#1513, @kasvith)\n- Rename `prql-compiler` binary to `prqlc` (@aljazerzen #1515)\n\n**Internal changes**:\n\n[This release, the changelog only contains a subset of internal changes]\n\n- Add parsing for negative select (@max-sixty, #1317)\n- Allow for additional builtin functions (@aljazerzen, #1325)\n- Add an automated check for typos (@max-sixty, #1421)\n- Add tasks for running playground & book (@max-sixty, #1265)\n- Add tasks for running tests on every file change (@max-sixty, #1380)\n\n**New contributors**:\n\n- @EArazli, with #1359\n- @boramalper, with #1362\n- @allurefx, with #1377\n- @bcho, with #1375\n- @JettChenT, with #1385\n- @BlurrechDev, with #1411\n- @BCsabaEngine, with #1432\n- @kasvith, with #1500\n\n## 0.3.1 - 2022-12-03\n\n0.3.1 brings a couple of small improvements and fixes.\n\n**Features**:\n\n- Support for using s-strings for `from` (#1197, @aljazerzen)\n\n  ```prql no-eval\n  from s\"SELECT * FROM employees WHERE foo > 5\"\n  ```\n\n- Helpful error message when referencing a table in an s-string (#1203,\n  @aljazerzen)\n\n**Fixes**:\n\n- Multiple columns with same name created (#1211, @aljazerzen)\n- Renaming via select breaks preceding sorting (#1204, @aljazerzen)\n- Same column gets selected multiple times (#1186, @mklopets)\n\n**Internal**:\n\n- Update Github Actions and Workflows to current version numbers (and avoid\n  using Node 12)\n\n## 0.3.0 — 2022-11-29\n\n🎉 0.3.0 is the biggest ever change in PRQL's compiler, rewriting much of the\ninternals: the compiler now has a semantic understanding of expressions,\nincluding resolving names & building a DAG of column lineage 🎉.\n\nWhile the immediate changes to the language are modest — some long-running bugs\nare fixed — this unlocks the development of many of the project's long-term\npriorities, such as type-checking & auto-complete. And it simplifies the\nbuilding of our next language features, such as match-case expressions, unions &\ntable expressions.\n\n@aljazerzen has (mostly single-handedly) done this work over the past few\nmonths. The project owes him immense appreciation.\n\n**Breaking changes**:\n\nWe've had to make some modest breaking changes for 0.3:\n\n- _Pipelines must start with `from`_. For example, a pipeline with only\n  `derive foo = 5`, with no `from` transform, is no longer valid. Depending on\n  demand for this feature, it would be possible to add this back.\n\n- _Shared column names now require `==` in a join_. The existing approach is\n  ambiguous to the compiler — `id` in the following example could be a boolean\n  column.\n\n  ```diff\n  from employees\n  -join positions [id]\n  +join positions [==id]\n  ```\n\n- _Table references containing periods must be surrounded by backticks_. For\n  example, when referencing a schema name:\n\n  ```diff\n  -from public.sometable\n  +from `public.sometable`\n  ```\n\n**Features**:\n\n- Change self equality op to `==` (#1176, @aljazerzen)\n- Add logging (@aljazerzen)\n- Add clickhouse dialect (#1090, @max-sixty)\n- Allow namespaces & tables to contain `.` (#1079, @aljazerzen)\n\n**Fixes**:\n\n- Deduplicate column appearing in `SELECT` multiple times (#1186, @aljazerzen)\n- Fix uppercase table names (#1184, @aljazerzen)\n- Omit table name when only one ident in SELECT (#1094, @aljazerzen)\n\n**Documentation**:\n\n- Add chapter on semantics' internals (@aljazerzen, #1028)\n- Add note about nesting variables in s-strings (@max-sixty, #1163)\n\n**Internal changes**:\n\n- Flatten group and window (#1120, @aljazerzen)\n- Split ast into expr and stmt (@aljazerzen)\n- Refactor associativity (#1156, @aljazerzen)\n- Rename Ident constructor to `from_name` (#1084, @aljazerzen)\n- Refactor rq folding (#1177, @aljazerzen)\n- Add tests for reported bugs fixes in semantic (#1174, @aljazerzen)\n- Bump duckdb from 0.5.0 to 0.6.0 (#1132)\n- Bump once_cell from 1.15.0 to 1.16.0 (#1101)\n- Bump pest from 2.4.0 to 2.5.0 (#1161)\n- Bump pest_derive from 2.4.0 to 2.5.0 (#1179)\n- Bump sqlparser from 0.25.0 to 0.27.0 (#1131)\n- Bump trash from 2.1.5 to 3.0.0 (#1178)\n\n## 0.2.11 — 2022-11-20\n\n0.2.11 contains a few helpful fixes.\n\nWork continues on our `semantic` refactor — look out for 0.3.0 soon! Many thanks\nto @aljazerzen for his continued contributions to this.\n\nNote: 0.2.10 was skipped due to this maintainer's inability to read his own docs\non bumping versions...\n\n**Features**:\n\n- Detect when compiler version is behind query version (@MarinPostma, #1058)\n- Add `__version__` to prql-python package (@max-sixty, #1034)\n\n**Fixes**:\n\n- Fix nesting of expressions with equal binding strength and left associativity,\n  such as `a - (b - c)` (@max-sixty, #1136)\n- Retain floats without significant digits as floats (@max-sixty, #1141)\n\n**Documentation**:\n\n- Add documentation of `prqlr` bindings (@eitsupi, #1091)\n- Add a 'Why PRQL' section to the website (@max-sixty, #1098)\n- Add @snth to core-devs (@max-sixty, #1050)\n\n**Internal changes**:\n\n- Use workspace versioning (@max-sixty, #1065)\n\n## 0.2.9 — 2022-10-14\n\n0.2.9 is a small release containing a bug fix for empty strings.\n\n**Fixes**:\n\n- Fix parsing of empty strings (@aljazerzen, #1024)\n\n## 0.2.8 — 2022-10-10\n\n0.2.8 is another modest release with some fixes, doc improvements, bindings\nimprovements, and lots of internal changes. Note that one of the fixes causes\nthe behavior of `round` and `cast` to change slightly — though it's handled as a\nfix rather than a breaking change in semantic versioning.\n\n**Fixes**:\n\n- Change order of the `round` & `cast` function parameters to have the column\n  last; for example `round 2 foo_col` / `cast int foo`. This is consistent with\n  other functions, and makes piping possible:\n\n  ```prql no-eval\n  derive [\n    gross_salary = (salary + payroll_tax | as int),\n    gross_salary_rounded = (gross_salary | round 0),\n  ]\n  ```\n\n**Documentation**:\n\n- Split `DEVELOPMENT.md` from `CONTRIBUTING.md` (@richb-hanover, #1010)\n- Make s-strings more prominent in website intro (@max-sixty, #982)\n\n**Web**:\n\n- Add GitHub star count to website (@max-sixty, #990)\n\n**Integrations**:\n\n- Expose a shortened error message, in particular for the VS Code extension\n  (@aljazerzen, #1005)\n\n**Internal changes**:\n\n- Specify 1.60.0 as minimum Rust version (@max-sixty, #1011)\n- Remove old `wee-alloc` code (@max-sixty, #1013)\n- Upgrade clap to version 4 (@aj-bagwell, #1004)\n- Improve book-building script in Taskfile (@max-sixty, #989)\n- Publish website using an artifact rather than a long-lived branch (@max-sixty,\n  #1009)\n\n## 0.2.7 — 2022-09-17\n\n0.2.7 is a fairly modest release, six weeks after 0.2.6. We have some more\nsignificant features, including a `union` operator and an overhaul of our type\nsystem, as open PRs which will follow in future releases.\n\nWe also have new features in the\n[VS Code extension](https://github.com/PRQL/prql-code), courtesy of\n@jiripospisil, including a live output panel.\n\n**Fixes**:\n\n- `range_of_ranges` checks the Range end is smaller than its start (@shuozeli,\n  #946)\n\n**Documentation**:\n\n- Improve various docs (@max-sixty, #974, #971, #972, #970, #925)\n- Add reference to EdgeDB's blog post in our FAQ (@max-sixty, #922)\n- Fix typos (@kianmeng, #943)\n\n**Integrations**:\n\n- Add `prql-lib`, enabling language bindings with `go` (@sigxcpu76, #923)\n- Fix line numbers in JS exceptions (@charlie-sanders, #929)\n\n**Internal changes**:\n\n- Lock the version of the rust-toolchain, with auto-updates (@max-sixty, #926,\n  #927)\n\n## 0.2.6 — 2022-08-05\n\n**Fixes**:\n\n- Adjust `fmt` to only escape names when needed (@aljazerzen, #907)\n- Fix quoting on upper case `table` names (@max-sixty, #893)\n- Fix scoping of identical column names from multiple tables (@max-sixty, #908)\n- Fix parse error on newlines in a `table` (@sebastiantoh 🆕, #902)\n- Fix quoting of upper case table names (@max-sixty, #893)\n\n**Documentation**:\n\n- Add docs on Architecture (@aljazerzen, #904)\n- Add Changelog (@max-sixty, #890 #891)\n\n**Internal changes**:\n\n- Start trial using Conventional Commits (@max-sixty, #889)\n- Add crates.io release workflow, docs (@max-sixty, #887)\n\n## 0.2.5 - 2022-07-29\n\n0.2.5 is a very small release following 0.2.4 yesterday. It includes:\n\n- Add the ability to represent single brackets in an s-string, with two brackets\n  (#752, @max-sixty)\n- Fix the \"Copy to Clipboard\" command in the Playground, for Firefox (#880,\n  @mklopets)\n\n## 0.2.4 - 2022-07-28\n\n0.2.4 is a small release following 0.2.3 a few days ago. The 0.2.4 release\nincludes:\n\n- Enrich our CLI, adding commands to get different stages of the compilation\n  process (@aljazerzen , #863)\n- Fix multiple `take n` statements in a query, leading to duplicate proxy\n  columns in generated SQL (@charlie-sanders)\n- Fix BigQuery quoting of identifiers in `SELECT` statements (@max-sixty)\n- Some internal changes — reorganize top-level functions (@aljazerzen), add a\n  workflow to track our Rust compilation time (@max-sixty), simplify our simple\n  prql-to-sql tests (@max-sixty)\n\nThanks to @ankane, `prql-compiler` is now available from homebrew core;\n`brew install prql-compiler`[^1].\n\n[^1]:\n    we still need to update docs and add a release workflow for this:\n    <https://github.com/PRQL/prql/issues/866>\n\n## 0.2.3 - 2022-07-24\n\nA couple of weeks since the 0.2.2 release: we've squashed a few bugs, added some\nmid-sized features to the language, and made a bunch of internal improvements.\n\nThe 0.2.3 release includes:\n\n- Allow for escaping otherwise-invalid identifiers (@aljazerzen & @max-sixty)\n- Fix a bug around operator precedence (@max-sixty)\n- Add a section the book on the language bindings (@charlie-sanders)\n- Add tests for our `Display` representation while fixing some existing bugs.\n  This is gradually becoming our code formatter (@arrizalamin)\n- Add a \"copy to clipboard\" button in the Playground (@mklopets)\n- Add lots of guidance to our `CONTRIBUTING.md` around our tests and process for\n  merging (@max-sixty)\n- Add a `prql!` macro for parsing a prql query at compile time (@aljazerzen)\n- Add tests for `prql-js` (@charlie-sanders)\n- Add a `from_json` method for transforming json to a PRQL string (@arrizalamin)\n- Add a workflow to release `prql-java` to Maven (@doki23)\n- Enable running all tests from a PR by adding a `pr-run-all-tests` label\n  (@max-sixty)\n- Have `cargo-release` to bump all crate & npm versions (@max-sixty)\n- Update `prql-js` to use the bundler build of `prql-js` (@mklopets)\n\nAs well as those contribution changes, thanks to those who've reported issues,\nsuch as @mklopets @huw @mm444 @ajfriend.\n\nFrom here, we're planning to continue squashing bugs (albeit more minor than\nthose in this release), adding some features like `union`, while working on\nbigger issues such as type-inference.\n\nWe're also going to document and modularize the compiler further. It's important\nthat we give more people an opportunity to contribute to the guts of PRQL,\nespecially given the number and enthusiasm of contributions to project in\ngeneral — and it's not that easy to do so at the moment. While this is ongoing\nif anyone has something they'd like to work on in the more difficult parts of\nthe compiler, let us know on GitHub or Discord, and we'd be happy to work\ntogether on it.\n\nThank you!\n\n## 0.2.2 - 2022-07-10\n\nWe're a couple of weeks since our 0.2.0 release. Thanks for the surge in\ninterest and contributions! 0.2.2 has some fixes & some internal improvements:\n\n- We now test against SQLite & DuckDB on every commit, to ensure we're producing\n  correct SQL. (@aljazerzen)\n- We have the beginning of Java bindings! (@doki23)\n- Idents surrounded by backticks are passed through to SQL (@max-sixty)\n- More examples on homepage; e.g. `join` & `window`, lots of small docs\n  improvements\n- Automated releases to homebrew (@roG0d)\n- [prql-js](https://github.com/PRQL/prql/tree/main/prqlc/bindings/js) is now a\n  single package for Node, browsers & webpack (@charlie-sanders)\n- Parsing has some fixes, including `>=` and leading underscores in idents\n  (@mklopets)\n- Ranges receive correct syntax highlighting (@max-sixty)\n\nThanks to Aljaž Mur Eržen @aljazerzen , George Roldugin @roldugin , Jasper\nMcCulloch @Jaspooky , Jie Han @doki23 , Marko Klopets @mklopets , Maximilian\nRoos @max-sixty , Rodrigo Garcia @roG0d , Ryan Russell @ryanrussell , Steven\nMaude @StevenMaude , Charlie Sanders @charlie-sanders .\n\nWe're planning to continue collecting bugs & feature requests from users, as\nwell as working on some of the bigger features, like type-inference.\n\nFor those interesting in joining, we also have a new\n[Contributing page](https://github.com/PRQL/prql/blob/main/.github/CONTRIBUTING.md).\n\n## 0.2.0 - 2022-06-27\n\n🎉 🎉 **After several months of building, PRQL is ready to use!** 🎉 🎉\n\n---\n\nHow we got here:\n\nAt the end of January, we published a proposal of a better language for data\ntransformation: PRQL. The reception was better than I could have hoped for — we\nwere no. 2 on HackerNews for a day, and gained 2.5K GitHub stars over the next\nfew days.\n\nBut man cannot live on GitHub Stars alone — we had to do the work to build it.\nSo over the next several months, during many evenings & weekends, a growing\ngroup of us gradually built the compiler, evolved the language, and wrote some\nintegrations.\n\nWe want to double-down on the community and its roots in open source — it's\nincredible that a few of us from all over the globe have collaborated on a\nproject without ever having met. We decided early-on that PRQL would always be\nopen-source and would never have a commercial product (despite lots of outside\ninterest to fund a seed round!). Because languages are so deep in the stack, and\nthe data stack has so many players, the best chance of building a great language\nis to build an open language.\n\n---\n\nWe still have a long way to go. While PRQL is usable, it has lots of missing\nfeatures, and an incredible amount of unfulfilled potential, including a\nlanguage server, cohesion with databases, and type inference. Over the coming\nweeks, we'd like to grow the number of intrepid users experimenting PRQL in\ntheir projects, prioritize features that will unblock them, and then start\nfulfilling PRQL's potential by working through our\n[roadmap](https://prql-lang.org/roadmap/).\n\nThe best way to experience PRQL is to try it. Check out our\n[website](https://prql-lang.org) and the\n[Playground](https://prql-lang.org/playground). Start using PRQL for your own\nprojects in [dbt](https://github.com/prql/dbt-prql),\n[Jupyter notebooks](https://pyprql.readthedocs.io/en/latest/magic_readme.html)\nand Prefect workflows.\n\nKeep in touch with PRQL by following the project on\n[Twitter](https://twitter.com/prql_lang), joining us on\n[Discord](https://discord.gg/eQcfaCmsNc), starring the\n[repo](https://github.com/PRQL/prql).\n\n[Contribute](https://github.com/PRQL/prql/blob/main/.github/CONTRIBUTING.md) to\nthe project — we're a really friendly community, whether you're a recent SQL\nuser or an advanced Rust programmer. We need bug reports, documentation tweaks &\nfeature requests — just as much as we need compiler improvements written in\nRust.\n\n---\n\nI especially want to give [Aljaž Mur Eržen](https://github.com/aljazerzen)\n(@aljazerzen) the credit he deserves, who has contributed the majority of the\ndifficult work of building out the compiler. Much credit also goes to\n@charlie-sanders, one of PRQL's earliest supporters and the author of pyprql,\nand [Ryan Patterson-Cross](https://github.com/rbpatt2019) (@rbpatt2019), who\nbuilt the Jupyter integration among other Python contributions.\n\nOther contributors who deserve a special mention include: @roG0d, @snth,\n@kwigley\n\n---\n\nThank you, and we look forward to your feedback!\n"

    "content": "# Claude\n\n## Development Workflow\n\nUse a tiered testing approach—iterate quickly, validate thoroughly:\n\n**Inner loop** (during development, ~5s):\n\n```sh\n# Fast tests on core packages\ntask prqlc:test\n\n# Filtered by test name\ncargo insta test -p prqlc --lib -- resolver\ncargo insta test -p prqlc --test integration -- date\n```\n\n**Before returning to user** (~30s):\n\n```sh\n# Comprehensive prqlc tests - sufficient for most changes\ntask prqlc:pull-request\n```\n\n**Cross-binding changes only** (~2min):\n\n```sh\n# Only when changes affect JS/Python/wasm bindings\ntask test-all\n```\n\nThe test suite is configured to minimize token usage:\n\n- **Nextest** only shows failures and slow tests (not 600 PASS lines)\n- **Cargo builds** use `--quiet` flag (no compilation spam)\n- **Result**: ~52% reduction in output (1128 → 540 lines, ~4.5k tokens)\n\n## Tests\n\nPrefer inline snapshots for almost all tests:\n\n```rust\ninsta::assert_snapshot!(result, @\"expected output\");\n```\n\nInitialize tests with empty snapshots, then run with `--accept`:\n\n```rust\ninsta::assert_snapshot!(result, @\"\");\n```\n\nThe test commands above with `--accept` will fill in the result automatically.\n\n### Test Strategy\n\n**Prefer small inline `insta` snapshot tests** over full integration tests:\n\n- **Use inline tests** for most bug fixes and small features\n  - Add `#[test]` functions in a `#[cfg(test)]` module at the end of the file\n  - Use `insta::assert_snapshot!` for compact, readable test assertions\n  - Fast to run, easy to review in PRs\n\n- **Use integration tests** (`prqlc/tests/integration/queries/*.prql`) only\n  when:\n  - Developing large, complex features that need comprehensive testing\n  - Testing end-to-end behavior across multiple compilation stages\n  - The test requires external resources or multi-file scenarios\n\nExample of a good inline test:\n\n```rust\n#[cfg(test)]\nmod test {\n    use insta::assert_snapshot;\n\n    #[test]\n    fn test_my_feature() {\n        let query = \"from employees | filter country == 'USA'\";\n        assert_snapshot!(crate::tests::compile(query).unwrap(), @\"\");\n    }\n}\n```\n\n## Running the CLI\n\nFor viewing `prqlc` output, for any stage of the compilation process:\n\n```sh\n# Compile PRQL to SQL\ncargo run -p prqlc -- compile \"from employees | filter country == 'USA'\"\n\n# Format PRQL code\ncargo run -p prqlc -- fmt \"from employees | filter country == 'USA'\"\n\n# See all available commands\ncargo run -p prqlc -- --help\n```\n\n## Linting\n\nRun all lints with\n\n```sh\ntask lint\n```\n\n## Error Handling\n\nNever panic on user input or recoverable errors. Use proper error returns:\n\n- ❌ `.unwrap()` on operations that can fail with user input\n- ✅ `?` operator or `return Err(Error::new_simple(\"message\"))`\n- ✅ `.expect(\"reason\")` or `unreachable!()` only for compiler-bug invariants\n\n## Error Messages\n\nError messages should avoid 2nd person (you/your). Use softer modal verbs like\n\"might\" for a friendlier tone:\n\n- ❌ \"are you missing `from` statement?\" → ✅ \"`from` statement might be\n  missing?\"\n- ❌ \"did you forget to specify the column name?\" → ✅ \"column name might be\n  missing?\"\n- ❌ \"you can only use X\" → ✅ \"X requires Y\" (for hard constraints)\n- ❌ \"Have you forgotten an argument?\" → ✅ \"Argument might be missing?\"\n\n## Documentation\n\nFor Claude to view crate documentation:\n\n```sh\n# Build documentation for a specific crate\ncargo doc -p prqlc\n\n# View the generated HTML documentation with the View tool\n# The docs are generated at target/doc/{crate_name}/index.html\nView target/doc/prqlc/index.html\n\n# For specific module documentation\nView target/doc/prqlc/module_name/index.html\n\n# For function documentation\nView target/doc/prqlc/fn.compile.html\n```\n\n## Releases & Environment\n\nFor releases or environment issues, see\n`web/book/src/project/contributing/development.md`.\n"

Like SQL, it's readable, explicit and declarative. Unlike SQL,\nit forms a logical pipeline of transformations, and supports abstractions such\nas variables and functions. It can be used with any database that uses SQL,\nsince it compiles to SQL.\n\nPRQL can be as simple as:\n\n```elm\nfrom tracks\nfilter artist == \"Bob Marley\"                 # Each line transforms the previous result\naggregate {                                   # `aggregate` reduces each column to a value\n  plays    = sum plays,\n  longest  = max length,\n  shortest = min length,                      # Trailing commas are allowed\n}\n```\n\nHere's a larger example of the language:\n\n```elm\nfrom employees\nfilter start_date > @2021-01-01               # Clear date syntax\nderive {                                      # `derive` adds columns / variables\n  gross_salary = salary + (tax ?? 0),         # Terse coalesce\n  gross_cost = gross_salary + benefits_cost,  # Variables can use other variables\n}\nfilter gross_cost > 0\ngroup {title, country} (                      # `group` runs a pipeline over each group\n  aggregate {                                 # `aggregate` reduces each group to a value\n    average gross_salary,\n    sum_gross_cost = sum gross_cost,          # `=` sets a column name\n  }\n)\nfilter sum_gross_cost > 100_000               # `filter` replaces both of SQL's `WHERE` & `HAVING`\nderive id = f\"{title}_{country}\"              # F-strings like Python\nderive country_code = s\"LEFT(country, 2)\"     # S-strings allow using SQL as an escape hatch\nsort {sum_gross_cost, -country}               # `-country` means descending order\ntake 1..20                                    # Range expressions (also valid here as `take 20`)\n```\n\nFor more on the language, more examples & comparisons with SQL, visit\n[prql-lang.org][prql website].

It'll\nalso let us scale the language without scaling the complexity of the compiler.\n\nWhile we figure that out, we're also thinking about:\n\n- Ensuring our supported features feel extremely robust; resolving any\n  [priority bugs](https://github.com/PRQL/prql/issues?q=is%3Aissue+is%3Aopen+label%3Abug+label%3Apriority).\n  As more folks have started using PRQL, we've had more bug reports — good news,\n  but also gives us more to work on.\n- Filling remaining feature gaps, so that PRQL is possible to use for almost all\n  standard SQL queries.\n- Expanding our set of supported features — we are working to add experimental\n  support for modules / multi-file projects, and for auto-formatting.\n\nAnd:\n\n- Making it really easy to start using PRQL. We're doing that by building\n  integrations with tools that folks already use; for example a VS Code\n  extension, Jupyter integration, and the recent\n  [QStudio](https://www.timestored.com/qstudio/prql-ide) integration. If there\n  are tools you're familiar with that you think would be open to integrating\n  with PRQL, please let us know in an issue.\n- Whether all our initial decisions were correct — for example\n  [how we handle window functions outside of a `window` transform](https://github.com/PRQL/prql/issues/2723).\n- Making it easier to contribute to the compiler. We have a wide group of\n  contributors to the project, but contributions to the compiler itself are\n  quite concentrated. We're keen to expand this;\n  [#1840](https://github.com/PRQL/prql/issues/1840) for feedback, some\n  suggestions on starter issues are below.\n\nWe're increasingly open to contributions for bigger rewrites of the resolver\ngiven how bottlenecked we are on it. If you're interested in contributing,\nplease reach out in an issue or on Discord.\n\n## Get involved\n\nTo stay in touch with PRQL:\n\n- Follow us on [Twitter](https://twitter.com/prql_lang)\n- Join us on [Discord](https://discord.gg/eQcfaCmsNc)\n- Star this repo\n- [Contribute][contributing] — join us in building PRQL, through writing code\n  [(send us your use-cases!)](https://github.com/PRQL/prql/discussions), or\n  inspiring others to use it.\n- See the [development][development] documentation for PRQL. It's easy to get\n  started — the project can be built in a couple of commands, and we're a really\n  friendly community!\n- For those who might be interested in contributing to the code now, check out\n  issues with the\n  [good first issue](https://github.com/PRQL/prql/labels/good%20first%20issue)\n  label. Always feel free to ask questions or open a draft PR.\n\n## Explore\n\n- [PRQL Playground][prql playground] — experiment with PRQL in the browser.\n- [PRQL Book][prql book] — the language documentation.\n- [Jupyter magic](https://pyprql.readthedocs.io/en/latest/magic_readme.html) —\n  run PRQL in Jupyter, either against a DB, or a Pandas DataFrame / CSV /\n  Parquet file through DuckDB.\n- [pyprql Docs](https://pyprql.readthedocs.io) — the pyprql documentation, the\n  Python bindings to PRQL, including Jupyter magic.\n- [PRQL VS Code extension](https://marketplace.visualstudio.com/items?itemName=prql-lang.prql-vscode)\n- [prqlc-js](https://www.npmjs.com/package/prqlc) — JavaScript bindings for\n  PRQL.\n\n## Repo organization\n\nThis repo is composed of:\n\n- **[prqlc](./prqlc/)** — the compiler, written in rust, whose main role is to\n  compile PRQL into SQL. Also contains the CLI and bindings from various\n  languages.\n- **[web](./web/)** — our web content: the [Book][prql book],\n  [Website][prql website], and [Playground][prql playground].\n\nIt also contains our testing / CI infrastructure and development tools.

Contributions are\nwelcome.\n\n## Installation\n\nMake sure that `libprqlc_c.so` (Linux), `libprqlc_c.dylib` (macOS) or\n`libprqlc_c.dll` (Windows) is in the project's `bin` directory together with\n`PrqlCompiler.dll` and the rest of the project's compiled files. I.e.\n`{your_project}/bin/Debug/net7.0/`.\n\nThe `libprqlc_c` library gets dynamically imported at runtime.\n\n## Usage\n\n```csharp\nusing Prql.Compiler;\n\nvar options = new PrqlCompilerOptions\n{\n    Format = false,\n    SignatureComment = false,\n};\nvar sql = PrqlCompiler.Compile(\"from employees\", options);\nConsole.WriteLine(sql);\n```\n\n## TODO\n\nThis is currently at 0.1.0 because we're waiting to update prqlc-c for the\nlatest API. When we've done that, we can match the version here with the broader\nPRQL version.\n"

This process is combined into the build of Java module.\n\nWe use [Maven](https://maven.apache.org/) to build the Java library. To add the\nRust cross compilation into the Maven build process, we add the following XML\nsegment to the `pom.xml`:\n\n```xml\n<plugin>\n    <artifactId>exec-maven-plugin</artifactId>\n    <groupId>org.codehaus.mojo</groupId>\n    <version>1.6.0</version>\n    <executions>\n        <execution>\n            <id>Build for release</id>\n            <phase>generate-resources</phase>\n            <goals>\n                <goal>exec</goal>\n            </goals>\n            <configuration>\n                <executable>../cross.sh</executable>\n                <arguments>\n                    <argument>${project.basedir}/../</argument>\n                </arguments>\n            </configuration>\n        </execution>\n    </executions>\n</plugin>\n```\n\nWhen we build, it will execute the `cross.sh` script to get all the Rust\ncdylibs. This process is time consuming.\n\nAs to cross compilation toolchains, we use\n[cross](https://github.com/cross-rs/cross).\n\n## Publish (for maintainer)\n\nTo publish the Java library to Maven public repo, project maintainer need first\nregister a project in the Maven Nexus repository, by the doc:\n<https://central.sonatype.org/publish/publish-guide/>.\n\nAnd then, we can release our artifact in the `release` workflow. The action we\nused is\n[action-maven-publish](https://github.com/marketplace/actions/action-maven-publish).\nProject maintainer has to configure some personal information, those used in the\nfirst step, by the action's doc, such as `nexus_username`, `nexus_password`,\n`gpg_private_key`, `gpg_passphrase`.\n"

It exposes a Java\nnative method `public static native String toSql(String query)`.\n\nIt's still at an early stage, and currently requires compiling locally, and\nisn't published to Maven. Contributions are welcome.\n\n## Installation\n\n```xml\n<dependency>\n    <groupId>org.prqllang</groupId>\n    <artifactId>prql-java</artifactId>\n    <version>${PRQL_VERSION}</version>\n</dependency>\n```\n\n## Usage\n\n```java\nimport org.prqllang.prql4j.PrqlCompiler;\n\nclass Main {\n    public static void main(String[] args) {\n        String sql = PrqlCompiler.toSql(\"from table\");\n        System.out.println(sql);\n    }\n}\n```\n"

Currently only Error is implemented.\n  kind: \"Error\" | \"Warning\" | \"Lint\";\n  /// Machine-readable identifier of the error\n  code: string | null;\n  /// Plain text of the error\n  reason: string;\n  /// A list of suggestions of how to fix the error\n  hint: string | null;\n  /// Character offset of error origin within a source file\n  span: [number, number] | null;\n\n  /// Annotated code, containing cause and hints.\n  display: string | null;\n  /// Line and column number of error origin within a source file\n  location: SourceLocation | null;\n}\n\n/// Location within the source file.\n/// Tuples contain:\n/// - line number (0-based),\n/// - column number within that line (0-based),\ninterface SourceLocation {\n  start: [number, number];\n\n  end: [number, number];\n}\n```\n\nThese errors can be caught as such:\n\n```javascript\ntry {\n  const sql = prqlJs.compile(`from employees | foo first_name`);\n} catch (error) {\n  const errorMessages = JSON.parse(error.message).inner;\n\n  console.log(errorMessages[0].display);\n  console.log(errorMessages[0].location);\n}\n```\n\n## Development\n\nBuild:\n\n```sh\nnpm run build\n```\n\nThis builds Node, bundler and web packages in the `dist` path.\n\nTest:\n\n```sh\nnpm test\n```\n\nBy default the `wasm` binaries are optimized on each run, even if the underlying\ncode hasn't changed, which can be slow. For a lower-latency dev loop, pass\n`--profile=dev` to `npm install` for a faster, less optimized build.\n\n```sh\nnpm install prqlc --profile=dev\n```\n\n## Notes\n\n- This uses [`wasm-pack`](https://rustwasm.github.io/docs/wasm-pack/) to\n  generate bindings[^1].\n- We've added an `npm` layer on top of the usual approach of just using\n  `wasm-pack`, so we can distribute a single package with targets of `node`,\n  `bundler` and `no-modules` — somewhat inverting the approach recommended by\n  `wasm-pack`. The build instruction goes in a `build` script, rather than a\n  `pack` script.\n\n[^1]:\n    Though we would be very open to other approaches, given wasm-pack does not\n    seem maintained, and we're eliding many of its features to build for three\n    targets. See <https://github.com/PRQL/prql/issues/1836> for more details.\n"

Contributions are\nwelcome.\n\n## Installation\n\nThe [PHP FFI extension](https://www.php.net/manual/en/book.ffi.php) needs to be\nenabled. Set `ffi.enable` in your php.ini configuration file to `\"true\"`.\n\n## Usage\n\n```php\n<?php\n\nuse Prql\\Compiler\\Compiler;\n\n$prql = new Compiler();\n$result = $prql->compile(\"from employees\");\n\necho $result->output;\n```\n\n## Development\n\n### Environment\n\nA way to establish a dev environment with PHP, the ext-ffi extension and\nComposer is to use a [nix flake](https://github.com/loophp/nix-shell). After\ninstalling nix, enable experimental flakes feature:\n\n```sh\nmkdir -p ~/.config/nix\necho \"experimental-features = nix-command flakes\" >> ~/.config/nix/nix.conf\n```\n\nNow you can spawn a shell from `prql-php/`:\n\n```sh\nnix shell github:loophp/nix-shell#env-php81 --impure\n```\n\nThis will pull-in ext-ffi extension, because it's declared in `composer.json`.\n\n### Building\n\nThere is a `task build-php` script that:\n\n- runs cargo to build `libprqlc_c`,\n- copies `libprqlc_c.*` into `lib`,\n- copies `prqlc.h` into `lib`.\n\n### Tests\n\n```sh\ntask build-php\ntask test-php\n```\n\n### Code style\n\n```sh\n./vendor/bin/phpcs --standard=PSR12 src tests\n```\n"

    "content": "# PRQL - Python Bindings\n\nPython bindings for [PRQL](https://github.com/PRQL/prql), the Pipelined\nRelational Query Language.\n\nPRQL is a modern language for transforming data — a simple, powerful, pipelined\nSQL replacement. Like SQL, it's readable, explicit and declarative. Unlike SQL,\nit forms a logical pipeline of transformations, and supports abstractions such\nas variables and functions. It can be used with any database that uses SQL,\nsince it compiles to SQL.\n\nPRQL can be as simple as:\n\n```\nfrom tracks\nfilter artist == \"Bob Marley\"     # Each line transforms the previous result\naggregate {                       # `aggregate` reduces each column to a value\n  plays    = sum plays,\n  longest  = max length,\n  shortest = min length,          # Trailing commas are allowed\n}\n```\n\n## Installation\n\n`pip install prqlc`\n\n## Usage\n\nBasic usage:\n\n```python\nimport prqlc\n\nprql_query = \"\"\"\n    from employees\n    join salaries (==emp_id)\n    group {employees.dept_id, employees.gender} (\n      aggregate {\n        avg_salary = average salaries.salary\n      }\n    )\n\"\"\"\n\noptions = prqlc.CompileOptions(\n    format=True, signature_comment=True, target=\"sql.postgres\"\n)\n\nsql = prqlc.compile(prql_query)\nsql_postgres = prqlc.compile(prql_query, options)\n```\n\nThe following functions and classes are exposed:\n\n```python\ndef compile(prql_query: str, options: Optional[CompileOptions] = None) -> str:\n    \"\"\"Compiles a PRQL query into SQL.\"\"\"\n    ...\n\ndef prql_to_pl(prql_query: str) -> str:\n    \"\"\"Converts a PRQL query to PL AST in JSON format.\"\"\"\n    ...\n\ndef pl_to_prql(pl_json: str) -> str:\n    \"\"\"Converts PL AST as a JSON string into a formatted PRQL string.\"\"\"\n    ...\n\ndef pl_to_rq(pl_json: str) -> str:\n    \"\"\"Resolves and lowers PL AST (JSON) into RQ AST (JSON).\"\"\"\n    ...\n\ndef rq_to_sql(rq_json: str, options: Optional[CompileOptions] = None) -> str:\n    \"\"\"Converts RQ AST (JSON) into a SQL query.\"\"\"\n    ...\n\nclass CompileOptions:\n    def __init__(\n        self,\n        *,\n        format: bool = True,\n        target: str = \"sql.any\",\n        signature_comment: bool = True,\n    ) -> None:\n    \"\"\"Compilation options for SQL backend of the compiler.\n\n    Args:\n        format (bool): Pass generated SQL string through a formatter that splits\n            it into multiple lines and prettifies indentation and spacing.\n            Defaults to True.\n        target (str): Target dialect to compile to. Defaults to \"sql.any\", which\n            uses the 'target' argument from the query header to determine the\n            SQL dialect. Other targets are available by calling the `get_targets`\n            function.\n        signature_comment (bool): Emits the compiler signature as a comment after\n            the generated SQL. Defaults to True.\n\n    \"\"\"\n    ...\n\ndef get_targets() -> list[str]:\n    \"\"\"List available target dialects for compilation.\"\"\"\n    ...\n```\n\n### Debugging functions\n\nThe following functions are available within the `prqlc.debug` module. They are\nfor experimental purposes and may be unstable.\n\n```python\ndef prql_lineage(prql_query: str) -> str:\n    \"\"\"Computes a column-level lineage graph from a PRQL query.\n\n    Returns JSON-formatted string. See the docs for the `prqlc debug lineage`\n    CLI command for more details.\n    \"\"\"\n    ...\n\ndef pl_to_lineage(pl_json: str) -> str:\n    \"\"\"Computes a column-level lineage graph from PL AST (JSON).\"\"\"\n    ...\n```\n\n## Development\n\nFor development, we use `uv` for fast dependency management:\n\n```sh\n# Install development dependencies and run tests\nuv run pytest\n\n# Run type checking\nuv run mypy\n\n# Or use the task runner\ntask test\n```\n\n## Notes\n\nThese bindings are in a crate named `prqlc-python` and published to a Python\npackage on PyPI named `prqlc`, available at <https://pypi.org/project/prqlc>.\nThis crate is not published to crates.io.\n\nThe package is consumed by [pyprql](https://github.com/prql/pyprql) &\n[dbt-prql](https://github.com/prql/dbt-prql).\n\nRelies on [pyo3](https://github.com/PyO3/pyo3) for all the magic.\n"

The stream of tokens, as Lexer Representation (LR), is\n   then parsed into an Abstract Syntax Tree (AST) called Parser Representation\n   (PR).\n\n2. **Semantic Analysis**: This stage resolves names (identifiers), extracts\n   declarations, and determines frames (table columns in each step). A `Context`\n   is declared containing the root module, which maps accessible names to their\n   declarations.\n\n   The resolving process involves the following operations:\n   - Assign an ID to each node (`Expr` and `Stmt`).\n   - Extract function declarations and variable definitions into the appropriate\n     `Module`, accessible from `Context::root_mod`.\n   - Look up identifiers in the module and find the associated declaration. The\n     identifier is replaced with a fully qualified name that guarantees a unique\n     name in `root_mod`. In some cases, `Expr::target` is also set.\n   - Convert function calls to transforms (`from`, `derive`, `filter`) from\n     `FuncCall` to `TransformCall`, which is more convenient for later\n     processing.\n   - Determine the type of expressions. If an expression is a reference to a\n     table, use the frame of the table as the type. If it is a `TransformCall`,\n     apply the transform to the input frame to obtain the resulting type. For\n     simple expressions, try to infer from `ExprKind`.\n   - Lowering: This stage converts the PL into RQ, which is more strictly typed\n     and contains less information but is convenient for translating into SQL or\n     other backends.\n\n3. **SQL Backend**: This stage converts RQ into PQ, an intermediate AST, before\n   finally converting to SQL. Each relation is transformed into an SQL query.\n   Pipelines are analyzed and split into \"AtomicPipelines\" at appropriate\n   positions, which can be represented by a single SELECT statement.\n\n   Splitting is performed back-to-front. First, a list of all output columns is\n   created. The pipeline is then traversed backwards, and splitting occurs when\n   an incompatible transform with those already present in the pipeline is\n   encountered. Splitting can also be triggered by encountering an expression\n   that cannot be materialized where it is used (e.g., a window function in a\n   WHERE clause).\n\n   This process is also called anchoring, as it anchors a column definition to a\n   specific location in the output query.\n\n   During this process, `sql::context` keeps track of:\n   - Table instances in the query (to prevent mixing up multiple instances of\n     the same table)\n   - Column definitions, whether computed or a reference to a table column\n   - Column names, as defined in RQ or generated\n"

It also serves as the CLI.\n\nFor more on PRQL, check out the [PRQL website](https://prql-lang.org) or the\n[PRQL repo](https://github.com/PRQL/prql).\n\n## CLI\n\n`prqlc` serves as a CLI for the PRQL compiler. It is a single, dependency-free\nbinary that compiles PRQL into SQL.\n\n## Usage\n\n### `prqlc compile`\n\nThis command works as a filter that compiles a PRQL string into an SQL string.\n\n```sh\n$ echo 'from employees | filter has_dog | select salary' | prqlc compile\n\nSELECT\n  salary\nFROM\n  employees\nWHERE\n  has_dog\n```\n\nA PRQL query can be executed with CLI tools compatible with SQL, such as\n[DuckDB CLI](https://duckdb.org/docs/api/cli.html).\n\n```sh\n$ curl -fsL https://raw.githubusercontent.com/PRQL/prql/0.12.2/prqlc/prqlc/tests/integration/data/chinook/albums.csv -o albums.csv\n$ echo 'from `albums.csv` | take 3' | prqlc compile | duckdb\n┌──────────┬───────────────────────────────────────┬───────────┐\n│ album_id │                 title                 │ artist_id │\n│  int64   │                varchar                │   int64   │\n├──────────┼───────────────────────────────────────┼───────────┤\n│        1 │ For Those About To Rock We Salute You │         1 │\n│        2 │ Balls to the Wall                     │         2 │\n│        3 │ Restless and Wild                     │         2 │\n└──────────┴───────────────────────────────────────┴───────────┘\n```\n\nExecuting this command without any argument will start interactive mode,\nallowing a PRQL query to be written interactively. In this mode, after writing\nPRQL and press `Ctrl-d` (Linux, macOS) or `Ctrl-z` (Windows) to display the\ncompiled SQL.\n\n```sh\nprqlc compile\n```\n\nJust like when using it as a filter, SQL string output can be passed to the\nDuckDB CLI and similar tools.\n\n```sh\n$ prqlc compile | duckdb\nEnter PRQL, then press ctrl-d to compile:\n\nfrom `albums.csv`\ntake 3\n┌──────────┬───────────────────────────────────────┬───────────┐\n│ album_id │                 title                 │ artist_id │\n│  int64   │                varchar                │   int64   │\n├──────────┼───────────────────────────────────────┼───────────┤\n│        1 │ For Those About To Rock We Salute You │         1 │\n│        2 │ Balls to the Wall                     │         2 │\n│        3 │ Restless and Wild                     │         2 │\n└──────────┴───────────────────────────────────────┴───────────┘\n```\n\n## Installation\n\n[![Packaging status](https://repology.org/badge/vertical-allrepos/prqlc.svg)](https://repology.org/project/prqlc/versions)\n\n### via Homebrew (macOS, Linux)\n\n```sh\nbrew install prqlc\n```\n\n### via winget (Windows)\n\n```sh\nwinget install prqlc\n```\n\n### From GitHub release page\n\nPrecompiled binaries are available for Linux, macOS, and Windows on the\n[PRQL release page](https://github.com/PRQL/prql/releases).\n\n### From source\n\n```sh\n# From crates.io\ncargo install prqlc\n```\n\n```sh\n# From a local PRQL repository\ncargo install --path prqlc/prqlc\n```\n\n### Shell completions\n\nThe `prqlc shell-completion` command prints a shell completion script for\nsupported shells, and saving the printed scripts to files makes for shells to\nload completions for each session.\n\n#### Bash\n\nFor Linux:\n\n```sh\nprqlc shell-completion bash >/etc/bash_completion.d/prqlc\n```\n\nFor macOS:\n\n```sh\nprqlc shell-completion bash >/usr/local/etc/bash_completion.d/prqlc\n```\n\n#### fish\n\n```sh\nprqlc shell-completion fish >~/.config/fish/completions/prqlc.fish\n```\n\n#### PowerShell\n\n```powershell\nmkdir -Path (Split-Path -Parent $profile) -ErrorAction SilentlyContinue\nprqlc shell-completion powershell >path/to/prqlc.ps1\necho 'Invoke-Expression -Command path/to/prqlc.ps1' >>$profile\n```\n\n#### zsh\n\n```sh\nprqlc shell-completion zsh >\"${fpath[1]}/_prqlc\"\n```\n\nEnsure that the following lines are present in `~/.zshrc`:\n\n```sh\nautoload -U compinit\ncompinit -i\n```\n\n## Helpers\n\nCheat sheets for `prqlc` are available on various websites and with various\ntools.\n\n- [`tldr`](https://tldr.sh/)\n  ([on the web](https://tldr.inbrowser.app/pages/common/prqlc))\n- [`eg`](https://github.com/srsudar/eg)\n\n<!-- Issues: #2034 cheat/cheatsheets, #2041 devhints.io -->\n\n## Library\n\nFor more usage examples and the library documentation, check out the\n[`prqlc` documentation](https://docs.rs/prqlc/).\n\n### Library installation\n\n```shell\ncargo add prqlc\n```\n\n### Examples\n\nCompile a PRQL string to a SQLite dialect string:\n\n```rust\n// In a file src/main.rs\n\nuse prqlc::{compile, Options, DisplayOptions, Target, sql::Dialect};\n\nlet prql = \"from employees | select {name, age}\";\nlet opts = &Options {\n    format: false,\n    target: Target::Sql(Some(Dialect::SQLite)),\n    signature_comment: false,\n    display: DisplayOptions::Plain,\n    ..Default::default()\n};\nlet sql = compile(&prql, opts).unwrap();\nassert_eq!(\"SELECT name, age FROM employees\", sql);\n```\n"

For inline strings, use the `prqlc-macros` crate; for example:\n//!   ```ignore\n//!   let sql: &str = prql_to_sql!(\"from albums | select {title, artist_id}\");\n//!   ```\n//!\n//!   For compiling whole files (`.prql` to `.sql`), call `prqlc` from\n//!   `build.rs`. See [this example\n//!   project](https://github.com/PRQL/prql/tree/main/prqlc/prqlc/examples/compile-files).\n//!\n//! - Compile, format & debug PRQL from command line.\n//!\n//!   ```sh\n//!   $ cargo install --locked prqlc\n//!   $ prqlc compile query.prql\n//!   ```\n//!\n//! ## Feature flags\n//!\n//! The following feature flags are available:\n//!\n//! * `cli`: enables the `prqlc` CLI binary. This is enabled by default. When\n//!   consuming this crate from another rust library, it can be disabled.\n//! * `test-dbs`: enables the `prqlc` in-process test databases as part of the\n//!   crate's tests. This significantly increases compile times so is not\n//!   enabled by default.\n//! * `test-dbs-external`: enables the `prqlc` external test databases,\n//!   requiring a docker container with the test databases to be running. Check\n//!   out the [integration tests](https://github.com/PRQL/prql/tree/main/prqlc/prqlc/tests/integration/dbs)\n//!   for more details.\n//! * `serde_yaml`: Enables serialization and deserialization of ASTs to YAML.\n//!\n//! ## Large binary sizes\n//!\n//! For Linux users, the binary size contributed by this crate will probably be\n//! quite large (>20MB) by default. That is because it includes a lot of\n//! debuginfo symbols from our parser. They can be removed by adding the\n//! following to `Cargo.toml`, reducing the contribution to around 7MB:\n//! ```toml\n//! [profile.release.package.prqlc]\n//! strip = \"debuginfo\"\n//! ```\n\nuse std::sync::OnceLock;\nuse std::{collections::HashMap, path::PathBuf, str::FromStr};\n\nuse anstream::adapter::strip_str;\nuse semver::Version;\nuse serde::{Deserialize, Serialize};\nuse strum::VariantNames;\n\npub use error_message::{ErrorMessage, ErrorMessages, SourceLocation};\npub use prqlc_parser::error::{Error, ErrorSource, Errors, MessageKind, Reason, WithErrorInfo};\npub use prqlc_parser::lexer::lr;\npub use prqlc_parser::parser::pr;\npub use prqlc_parser::span::Span;\n\nmod codegen;\npub mod debug;\nmod error_message;\npub mod ir;\npub mod parser;\npub mod semantic;\npub mod sql;\n#[cfg(feature = \"cli\")]\npub mod utils;\n#[cfg(not(feature = \"cli\"))]\npub(crate) mod utils;\n\npub type Result<T, E = Error> = core::result::Result<T, E>;\n\n/// Get the version of the compiler.

operations support matrix\n\nSet-ops have quite different support in major SQL dialects. This is an attempt to document it.\n\n| SQL construct                 | SQLite  | BQ     | Postgres | MySQL 8+ | DuckDB\n|-------------------------------|---------|--------|----------|----------|--------\n| UNION (implicit DISTINCT)     | x       |        | x        | x        | x\n| UNION DISTINCT                |         | x      | x        | x        | x\n| UNION ALL                     | x       | x      | x        | x        | x\n| EXCEPT (implicit DISTINCT)    | x       |        | x        | x        | x\n| EXCEPT DISTINCT               |         | x      | x        | x        | x\n| EXCEPT ALL                    |         |        | x        | x        |\n\n\n### UNION DISTINCT\n\nFor UNION, these are equivalent:\n- a UNION DISTINCT b,\n- DISTINCT (a UNION ALL b)\n- DISTINCT (a UNION ALL (DISTINCT b))\n- DISTINCT ((DISTINCT a) UNION ALL b)\n- DISTINCT ((DISTINCT a) UNION ALL (DISTINCT b))\n\n\n### EXCEPT DISTINCT\n\nFor EXCEPT it makes a difference when DISTINCT is applied. Below is a test query to validate\nthe behavior. When applied before EXCEPT, the output should be [3] and when applied after EXCEPT,\nthe output should be [2, 3].\n\n```\nSELECT * FROM (SELECT 1 UNION ALL SELECT 2 UNION ALL SELECT 2 UNION ALL SELECT 3) t\nEXCEPT\nSELECT * FROM (SELECT 1 UNION ALL SELECT 2) t;\n```\n\nAll dialects seem to be applying *before*, but none seem to document that.\n\n\n### INTERSECT DISTINCT\n\nFor INTERSECT, it does not matter when DISTINCT is applied. BigQuery documentation does mention\nit is applied *after*, which makes me think there is a difference I'm not seeing.\n\nMy reasoning is that:\n- Distinct is equivalent to applying `group * (take 1)`.\n- In effect, this is a restriction that \"each group can have at most one value\".\n- If we apply DISTINCT to any input of INTERSECT ALL, this restriction on the input is retained\n  through the operation. That's because no group will not contain more values than it started with,\n  and no group that was present in both inputs, will be missing from the output.\n- Thus, applying distinct after INTERSECT ALL is equivalent to applying it to any of the inputs.\n\n*/\n"

    "content": "# PRQL test-databases\n\nTest PRQL queries against various SQL RDBMS.\n\n## In-process DBs\n\nTo run tests against DuckDB & SQLite, no additional setup is required; simply\nrun:\n\n```sh\ncargo test --features=test-dbs\n```\n\n## External DBs\n\nTo run tests against external databases — currently Postgres, MySQL, SQL Server,\nClickHouse and GlareDB are tested using `docker compose` to create the\ndatabases.\n\nThe steps are all covered by `task test-rust-external-dbs`; to run them\nmanually:\n\n1. Run `docker compose up` (may take a while on the first time):\n\n   ```sh\n   cd prqlc/prqlc/tests/integration/dbs && docker compose up -d\n   ```\n\n2. Run the tests:\n\n   ```sh\n   cargo test --features=test-dbs-external -- --nocapture\n   ```\n\n   (The `--no-capture` option isn't required, but shows all the dialects tested\n   per query.)\n\n3. After it's done, remove the containers:\n\n   ```sh\n   cd prqlc/prqlc/tests/integration/dbs && docker compose down\n   ```\n\nNote: on an M1, if the MSSQL docker container doesn't run, refer to\n[this comment](https://github.com/microsoft/mssql-docker/issues/668#issuecomment-1436802153)\n\n## Tested databases\n\nTests are by default run on all the DBs with `SupportLevel::Supported`.\n\nTo test on a DB that is not yet at this support level like `MSSQL`, simply add\n`# mssql:test` on top of the query. To ignore one of the supported DBs like\n`sqlite`, simply add `# sqlite:skip` on top of the query.\n\n## Data\n\nColumns are renamed to `snake_case`, so Postgres and DuckDb don't struggle with\nthem.\n\nFor optimal accessibility, portability between databases and file size, all\ntables are stored as CSV files. Their current size is 432kB, it could be gzip-ed\nto 112kB, but that would require a preprocessing step before running\n`cargo test`.\n\n## Queries\n\nFor databases like ClickHouse, where the order of results is ambiguous, please\nuse `sort` for test queries to to guarantee the order of rows across DBs.\n\nFor example, instead of the following query:\n\n```elm\nfrom albums\n```\n\nUse a query including `sort`:\n\n```elm\nfrom albums\nsort album_id\n```\n\n## Test organization\n\nWe follow the advice in\n<https://matklad.github.io/2021/02/27/delete-cargo-integration-tests.html>.\n"

Like SQL, it's readable, explicit and declarative. Unlike SQL,\nit forms a logical pipeline of transformations, and supports abstractions such\nas variables and functions. It can be used with any database that uses SQL,\nsince it compiles to SQL.\n\nThis book serves as a tutorial and reference guide on the language and the\nbroader project. It currently has three sections, navigated by links on the\nleft:\n\n- **Tutorial** — A friendly & accessible guide for learning PRQL. It has a\n  gradual increase of difficulty and requires only basic understanding of\n  programming languages. Knowledge of SQL is beneficial, because of many\n  comparisons to SQL, but not required.\n- **Reference** — In-depth information about the PRQL language. Includes\n  justifications for language design decisions and formal specifications for\n  parts of the language.\n- **Project** — General information about the project, tooling and development.\n\n---\n\n**Examples of PRQL** with a comparison to the generated SQL. PRQL queries can be\nas simple as:\n\n```prql\nfrom tracks\nfilter artist == \"Bob Marley\"  # Each line transforms the previous result\naggregate {                    # `aggregate` reduces each column to a value\n  plays    = sum plays,\n  longest  = max length,\n  shortest = min length,       # Trailing commas are allowed\n}\n```\n\n...and here's a larger example:\n\n```prql\nfrom employees\nfilter start_date > @2021-01-01            # Clear date syntax\nderive {                                   # `derive` adds columns / variables\n  gross_salary = salary + (tax ?? 0),      # Terse coalesce\n  gross_cost = gross_salary + benefits,    # Variables can use other variables\n}\nfilter gross_cost > 0\ngroup {title, country} (                   # `group` runs a pipeline over each group\n  aggregate {                              # `aggregate` reduces each group to a value\n    average gross_salary,\n    sum_gross_cost = sum gross_cost,       # `=` sets a column name\n  }\n)\nfilter sum_gross_cost > 100_000            # `filter` replaces both of SQL's `WHERE` & `HAVING`\nderive id = f\"{title}_{country}\"           # F-strings like Python\nderive country_code = s\"LEFT(country, 2)\"  # S-strings permit SQL as an escape hatch\nsort {sum_gross_cost, -country}            # `-country` means descending order\ntake 1..20                                 # Range expressions (also valid as `take 20`)\n```\n"

We're actively\nlooking for collaborators to lead that growth with us.\n\n## Areas for larger contributions\n\n### Compiler\n\nThe compiler is written in Rust, and there's enough to do such that any level of\nexperience with Rust is sufficient.\n\nWe try to keep a few onboarding issues on hand under the\n[\"good first issue\" label](https://github.com/PRQL/prql/labels/good%20first%20issue).\nThese have been screened to have sufficient context to get started (and we very\nmuch welcome questions where there's some context missing).\n\nTo get started, check out the docs on [Development](./development.md) and the\n[Compiler architecture](https://github.com/PRQL/prql/blob/main/prqlc/prqlc/ARCHITECTURE.md)\n\nAnd if you have questions, there are lots of friendly people on the Discord who\nwill patiently help you.\n\n### Bindings & integrations\n\nFor PRQL to be successful, it needs to be available for the languages & tools\nthat people already use.\n\n- We currently have bindings to the PRQL compiler in a few different languages;\n  many of these can be improved, documented, and packaged in a better way.\n- If you have experience with packaging in an ecosystem that doesn't currently\n  have bindings, then creating PRQL bindings for that language we don't\n  currently support would be valuable to the project.\n- If there's a tool that you use yourself to run data queries which you think\n  would benefit from a PRQL integration, suggest one to us or the tool. If it's\n  open-source, build & share a prototype.\n\nRelevant issues are labeled\n[Integrations](https://github.com/PRQL/prql/labels/integrations).\n\n### Language design\n\nWe decide on new language features in GitHub issues, usually under\n[\"language design\" label](https://github.com/PRQL/prql/issues?q=is%3Aopen+label%3Alanguage-design+sort%3Aupdated-desc).\n\nYou can also contribute by:\n\n- Finding instances where the compiler produces incorrect results, and post a\n  bug report — feel free to use the\n  [playground](https://prql-lang.org/playground).\n- Opening an issue / append to an existing issue with examples of queries that\n  are difficult to express in PRQL — especially if more difficult than SQL.\n\nWith sufficient examples, suggest a change to the language! (Though suggestions\n_without_ examples are difficult to engage with, so please do anchor suggestions\nin examples.)\n\n### Marketing\n\n- Improve our website. We have\n  [a few issues open](https://github.com/PRQL/prql/labels/web) on this front and\n  are looking for anyone with at least some design skills.\n- Contribute towards the docs. Anything from shaping a whole section of the\n  docs, to simply improving a confusing paragraph or fixing a typo.\n- Tell people about PRQL.\n- Find a group of users who would be interested in PRQL, help them get up to\n  speed, help the project understand what they need.\n\n## Core team\n\nIf you have any questions or feedback and don't receive a response on one of the\ngeneral channels such as GitHub or Discord, feel free to reach out to:\n\n- [**@aljazerzen**](https://github.com/aljazerzen) — Aljaž Mur Eržen\n- [**@max-sixty**](https://github.com/max-sixty) — Maximilian Roos\n- [**@eitsupi**](https://github.com/eitsupi) — SHIMA Tatsuya\n- [**@snth**](https://github.com/snth) — Tobias Brandt\n\n### Core team Emeritus\n\nThank you to those who have previously served on the core team:\n\n- **@charlie-sanders** — Charlie Sanders\n"

    "content": "# Development\n\n## Setting up an initial dev environment\n\nWe can set up a local development environment sufficient for navigating,\nediting, and testing PRQL's compiler code in two minutes:\n\n- Install\n  [`rustup` & `cargo`](https://doc.rust-lang.org/cargo/getting-started/installation.html).\n- [Optional but highly recommended] Install `cargo-insta`, our testing\n  framework:\n\n  ```sh\n  cargo install cargo-insta\n  ```\n\n- That's it! Running the unit tests for the `prqlc` crate after cloning the repo\n  should complete successfully:\n\n  ```sh\n  cargo test --package prqlc --lib\n  ```\n\n  ...or, to run tests and update the test snapshots:\n\n  ```sh\n  cargo insta test --accept --package prqlc --lib\n  ```\n\n  There's more context on our tests in [How we test](#how-we-test) below.\n\nThat's sufficient for making an initial contribution to the compiler.\n\n---\n\n## Setting up a full dev environment\n\n<!-- prettier-ignore -->\n> [!NOTE]\n> We really care about this process being easy, both because the project\n> benefits from more contributors like you, and to reciprocate your future\n> contribution. If something isn't easy, please let us know in a GitHub Issue.\n> We'll enthusiastically help you, and use your feedback to improve the scripts\n> & instructions.\n\nFor more advanced development; for example compiling for wasm or previewing the\nwebsite, we have two options:\n\n### Option 1: Use the project's `task`\n\n<!-- prettier-ignore -->\n> [!NOTE]\n> This is tested on macOS, should work on amd64 Linux, but won't work on\n> others (include Windows), since it relies on `brew`.\n\n- [Install Task](https://taskfile.dev/installation/).\n- Then run the `setup-dev` task. This runs commands from our\n  [Taskfile.yaml](https://github.com/PRQL/prql/blob/main/Taskfile.yaml),\n  installing dependencies with `cargo`, `brew`, `npm` & `uv`, and suggests some\n  VS Code extensions.\n\n  ```sh\n  task setup-dev\n  ```\n\n### Option 2: Install tools individually\n\n- We'll need `cargo-insta`, to update snapshot tests:\n\n  ```sh\n  cargo install cargo-insta\n  ```\n\n- We'll need Python, which most systems will have already. The easiest way to\n  check is to try running the full tests:\n\n  ```sh\n  cargo test\n  ```\n\n  ...and if that doesn't complete successfully, ensure we have Python >= 3.7, to\n  compile `prqlc-python`.\n\n- For more involved contributions, such as building the website, playground,\n  book, or some release artifacts, we'll need some additional tools. But we\n  won't need those immediately, and the error messages on what's missing should\n  be clear when we attempt those things. When we hit them, the\n  [Taskfile.yaml](https://github.com/PRQL/prql/blob/main/Taskfile.yaml) will be\n  a good source to copy & paste instructions from.\n\n### Option 3: Use a Dev Container\n\nThis project has a\n[devcontainer.json file](https://github.com/PRQL/prql/blob/main/.devcontainer/devcontainer.json)\nand a\n[pre-built dev container base Docker image](https://github.com/PRQL/prql/pkgs/container/prql-devcontainer-base).\nLearn more about Dev Containers at\n[https://containers.dev/](https://containers.dev/)\n\nCurrently, the tools for Rust are already installed in the pre-built image, and,\nNode.js, Python and others are configured to be installed when build the\ncontainer.\n\nWhile there are a variety of tools that support Dev Containers, the focus here\nis on developing with VS Code in a container by\n[GitHub Codespaces](https://docs.github.com/en/codespaces/overview) or\n[VS Code Dev Containers extension](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-containers).\n\nTo use a Dev Container on a local computer with VS Code, install the\n[VS Code Dev Containers extension](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-containers)\nand its system requirements. Then refer to the links above to get started.\n\n### Option 4: Use nix development environment\n\n<!-- prettier-ignore -->\n> [!NOTE]\n> This is used by a member of the core team on Linux, but doesn't\n> currently work on Mac. We're open to contributions to improve support.\n\nA [nix](https://nixos.org/) flake `flake.nix` provides 3 development\nenvironments:\n\n- **default**, for building the compiler\n- **web**, for the compiler and the website,\n- **full**, for the compiler, the website and the compiler bindings.\n\nTo load the shell:\n\n1. [Install nix (the package manager)](https://nixos.org/download). (only first\n   time)\n\n2. Enable flakes, which are a (pretty stable) experimental feature of nix. (only\n   first time)\n\n   For non-NixOS users:\n\n   ```sh\n   mkdir -p ~/.config/nix/\n   tee 'experimental-features = nix-command flakes' >> ~/.config/nix/nix.conf\n   ```\n\n   For NixOS users, follow instructions [here](https://nixos.wiki/wiki/Flakes).\n\n3. Run:\n\n   ```sh\n   nix develop\n   ```\n\n   To use the \"web\" or \"full\" shell, run:\n\n   ```sh\n   nix develop .#web\n   ```\n\nOptionally, you can install [direnv](https://direnv.net/), to automatically load\nthe shell when you enter this repo. The easiest way is to also install\n[direnv-nix](https://github.com/nix-community/nix-direnv) and configure your\n`.envrc` with:\n\n```sh\n# .envrc\nuse flake .#full\n```\n\n---\n\n## Contribution workflow\n\nWe're similar to most projects on GitHub — open a Pull Request with a suggested\nchange!\n\n### Commits\n\n- If a change is user-facing, please add a line in\n  [**`CHANGELOG.md`**](https://github.com/PRQL/prql/blob/main/CHANGELOG.md),\n  with `{message}, ({@contributor, #X})` where `X` is the PR number.\n  - If there's a missing entry, a follow-up PR containing just the changelog\n    entry is welcome.\n- We're using [Conventional Commits](https://www.conventionalcommits.org)\n  message format, enforced through\n  [action-semantic-pull-request](https://github.com/amannn/action-semantic-pull-request).\n\n### Merges\n\n- **We merge any code that makes PRQL better**\n- A PR doesn't need to be perfect to be merged; it doesn't need to solve a big\n  problem. It needs to:\n  - be in the right direction,\n  - make incremental progress,\n  - be explicit on its current state, so others can continue the progress.\n- That said, there are a few instances when we need to ensure we have some\n  consensus before merging code — for example non-trivial changes to the\n  language, or large refactorings to the library.\n- If you have merge permissions, and are reasonably confident that a PR is\n  suitable to merge (whether or not you're the author), feel free to merge.\n  - If you don't have merge permissions and have authored a few PRs, ask and ye\n    shall receive.\n- The primary way we ratchet the code quality is through automated tests.\n  - This means PRs almost always need a test to demonstrate incremental\n    progress.\n  - If a change breaks functionality without breaking tests, our tests were\n    probably insufficient.\n  - If a change breaks existing tests (for example, changing an external API),\n    that indicates we should be careful about merging a change, including\n    soliciting others' views.\n- We use PR reviews to give general context, offer specific assistance, and\n  collaborate on larger decisions.\n  - Reviews around 'nits' like code formatting / idioms / etc are very welcome.\n    But the norm is for them to be received as helpful advice, rather than as\n    mandatory tasks to complete. Adding automated tests & lints to automate\n    these suggestions is welcome.\n  - If you have merge permissions and would like a PR to be reviewed before it\n    merges, that's great — ask or assign a reviewer.\n  - If a PR hasn't received attention after a day, please feel free to ping the\n    pull request.\n- People may review a PR after it's merged. As part of the understanding that we\n  can merge quickly, contributors are expected to incorporate substantive\n  feedback into a future PR.\n- We should revert quickly if the impact of a PR turns out not to be consistent\n  with our expectations, or there isn't as much consensus on a decision as we\n  had hoped. It's very easy to revert code and then re-revert when we've\n  resolved the issue; it's a sign of moving quickly. Other options which resolve\n  issues immediately are also fine, such as commenting out an incorrect test or\n  adding a quick fix for the underlying issue.\n\n## Docs\n\nWe're very keen on contributions to improve our documentation.\n\nThis includes our docs in the book, on the website, in our code, or in a Readme.\nWe also appreciate issues pointing out that our documentation was confusing,\nincorrect, or stale — if it's confusing for you, it's probably confusing for\nothers.\n\nSome principles for ensuring our docs remain maintainable:\n\n- Docs should be as close as possible to the code. Doctests are ideal on this\n  dimension — they're literally very close to the code and they can't drift\n  apart since they're tested on every commit. Or, for example, it's better to\n  add text to a `--help` message, rather than write a paragraph in the Readme\n  explaining the CLI.\n- We should have some visualization of how to maintain docs when we add them.\n  Docs have a habit of falling out of date — the folks reading them are often\n  different from those writing them, they're sparse from the code, generally not\n  possible to test, and are rarely the by-product of other contributions. Docs\n  that are concise & specific are easier to maintain.\n- Docs should be specifically relevant to PRQL; anything else we can instead\n  link to.\n\nIf something doesn't fit into one of these categories, there are still lots of\nways of getting the word out there — a blog post / gist / etc. Let us know and\nwe're happy to link to it / tweet it.\n\n## How we test\n\nWe use a pyramid of tests — we have fast, focused tests at the bottom of the\npyramid, which give us low latency feedback when developing, and then slower,\nbroader tests which ensure that we don't miss anything as PRQL\ndevelops{{footnote: Our approach is very consistent with\n**[@matklad](https://github.com/matklad)**'s advice, in his excellent blog\npost [How to\nTest](https://matklad.github.io//2021/05/31/how-to-test.html).}}.\n\n<!-- markdownlint-disable MD053 -->\n\n<!-- prettier-ignore -->\n> [!NOTE]\n> If you're making your first contribution, you don't need to engage\n> with all this — it's fine to just make a change and push the results; the\n> tests that run in GitHub will point you towards any errors, which can be then\n> be run locally if needed. We're always around to help out.\n\nOur tests, from the bottom of the pyramid to the top:\n\n- **[Static checks](https://github.com/PRQL/prql/blob/main/.pre-commit-config.yaml)**\n  — we run a few static checks to ensure the code stays healthy and consistent.\n  They're defined in\n  [**`.pre-commit-config.yaml`**](https://github.com/PRQL/prql/blob/main/.pre-commit-config.yaml),\n  using [pre-commit](https://pre-commit.com). They can be run locally with\n\n  ```sh\n  task lint\n  # or\n  pre-commit run -a\n  ```\n\n  The tests fix most of the issues they find themselves. Most of them also run\n  on GitHub on every commit; any changes they make are added onto the branch\n  automatically in an additional commit.\n  - Checking by [MegaLinter](https://megalinter.io/latest/), which includes more\n    Linters, is also done automatically on GitHub. (experimental)\n\n- **Unit tests & inline insta snapshots** — we rely on unit tests to rapidly\n  check that our code basically works. We extensively use\n  [Insta](https://insta.rs/), a snapshot testing tool which writes out the\n  values generated by our code, making it fast & simple to write and modify\n  tests{{footnote:\n  [Here's an example of an insta test](https://github.com/PRQL/prql/blob/0.2.2/prql-compiler/src/parser.rs#L580-L605)\n  — note that only the initial line of each test is written by us; the\n  remainder is filled in by insta.}}\n\n  These are the fastest tests which run our code; they're designed to run on\n  every save while you're developing. We include a `task` which does this:\n\n  ```sh\n  task prqlc:test\n  # or\n  cargo insta test --accept --package prqlc --lib\n  ```\n\n<!--\nThis is the previous doc. It has the advantage that it explains what it's doing, and is\neasy to change (e.g. to run all packages). But because of\nhttps://github.com/watchexec/watchexec/issues/371, the ignore behavior is unfortunately quite\ninconsistent in watchexec. Let's revert back if it gets solved.\n\n[^2]: For example, this is a command I frequently run:\n\n    ```sh\n    RUST_BACKTRACE=1 watchexec -e rs,toml,md -cr --ignore='target/**' -- cargo -q insta test --accept -p prqlc --lib\n    ```\n\n    Breaking this down:\n\n    - `RUST_BACKTRACE=1` will print a full backtrace, including where an error\n      value was created, for Rust tests which return `Result`s.\n    - `watchexec -e rs,toml,md -cr --ignore='target/**' --` will run the\n      subsequent command on any change to files with extensions which we are\n      generally editing.\n    - `cargo insta test --accept --` runs tests with `insta`, a snapshot\n      library, and writes any results immediately. I rely on git to track\n      changes, so I run with `--accept`, but YMMV.\n    - `-p prqlc --lib` is passed to cargo by `insta`; `-p prqlc`\n      tells it to only run the tests for `prqlc` rather than the other\n      crates, and `--lib` to only run the unit tests rather than the integration\n      tests, which are slower.\n    - Note that we don't want to re-run on _any_ file changing, because we can\n      get into a loop of writing snapshot files, triggering a change, writing a\n      snapshot file, etc. -->\n\n- **[Documentation](https://github.com/PRQL/prql/tree/main/web/book/tests/documentation)**\n  — we compile all examples from our documentation in the Website, README, and\n  PRQL Book, to test that they produce the SQL we expect, and that changes to\n  our code don't cause any unexpected regressions. These are included in:\n\n  ```sh\n  cargo insta test --accept\n  ```\n\n- **[Database integration tests](https://github.com/PRQL/prql/tree/main/prqlc/prqlc/tests/integration/dbs)**\n  — we run tests with example queries against databases with actual data to\n  ensure we're producing correct SQL across our supported dialects. The\n  in-process tests can be run locally with:\n\n  ```sh\n  task prqlc:test-all\n  # or\n  cargo insta test --accept --features=default,test-dbs\n  ```\n\n  More details on running with external databases are in the\n  [Readme](https://github.com/PRQL/prql/tree/main/prqlc/prqlc/tests/integration/dbs).\n\n<!-- prettier-ignore -->\n> [!NOTE]\n> Integration tests use DuckDB, and so require a clang compiler to\n> compile [`duckdb-rs`](https://github.com/wangfenjin/duckdb-rs). Most\n> development systems will have one, but if the test command fails, install a\n> clang compiler with:\n>\n> - On macOS, install xcode with `xcode-select --install`\n> - On Debian Linux, `apt-get update && apt-get install clang`\n> - On Windows, `duckdb-rs` isn't supported, so these tests are excluded\n\n- **[GitHub Actions on every commit](https://github.com/PRQL/prql/blob/main/.github/workflows/tests.yaml)**\n  — we run tests relevant to a PR's changes in CI — for example changes to docs\n  will attempt to build docs, changes to a binding will run that binding's\n  tests. The vast majority of changes trigger tests which run in less than five\n  minutes, and we should be reassessing their scope if they take longer than\n  that. Once these pass, a pull request can be merged.\n\n- **[GitHub Actions on merge](https://github.com/PRQL/prql/blob/c042eef48709e2c1af577161554fd09f14e67e0f/.github/workflows/pull-request.yaml#L124)**\n  — we run a wider set tests on every merge to main. This includes testing\n  across OSs, all our language bindings, a measure of test code coverage, and\n  some performance benchmarks.\n\n  If these tests fail after merging, we should revert the commit before fixing\n  the test and then re-reverting.\n\n  Most of these will run locally with:\n\n  ```sh\n  task test-all\n  ```\n\n- **[GitHub Actions nightly](https://github.com/PRQL/prql/blob/main/.github/workflows/nightly.yaml)**\n  — every night, we run tests that take longer, are less likely to fail, or are\n  unrelated to code changes — such as security checks, bindings' tests on\n  multiple OSs, or expensive timing benchmarks.\n\n  We can run these tests before a merge by adding a label `pr-nightly` to the\n  PR.\n\nThe goal of our tests is to allow us to make changes quickly. If they're making\nit more difficult to make changes, or there are missing tests that would offer\nthe confidence to make changes faster, please raise an issue.\n\n---\n\n## Website\n\nThe website is published together with the book and the playground, and is\nautomatically built and released on any push to the `web` branch.\n\nThe `web` branch points to the latest release plus any website-specific fixes.\nThat way, the compiler behavior in the playground matches the latest release\nwhile allowing us to fix mistakes in the docs with a tighter loop than every\nrelease.\n\nFixes to the playground, book, or website should have a `pr-backport-web` label\nadded to their PR — a bot will then open & merge another PR onto the `web`\nbranch once the initial branch merges.\n\nThe website components will run locally with:\n\n```sh\n# Run the main website\ntask web:run-website\n# Run the PRQL online book\ntask web:run-book\n# Run the PRQL playground\ntask web:run-playground\n```\n\n## Bindings\n\nWe have a number of language bindings, as documented at\n<https://prql-lang.org/book/project/bindings/index.html>. Some of these are\nwithin our monorepo, some are in separate repos. Here's a provisional framework\nfor when we use the main prql repo vs separate repos for bindings:\n\n| Factor                                           | Rationale                                                                                  | Example                                                       |\n| ------------------------------------------------ | ------------------------------------------------------------------------------------------ | ------------------------------------------------------------- |\n| Does someone want to sign up to maintain a repo? | A different repo is harder for the core team to maintain                                   | `tree-sitter-prql` is well maintained                         |\n| Can it change independently from the compiler?   | If it's in a different repo, it can't be changed in lockstep with the compiler             | `prql-vscode` is fine to change \"behind\" the language         |\n| Would a separate repo invite new contributors?   | A monorepo with all the rust code can be less inviting for those familiar with other langs | `prql-vscode` had some JS-only contributors                   |\n| Is there an convention for a stand-alone repo?   | A small number of ecosystems require a separate repo                                       | `homebrew-prql` needs to be named that way for a Homebrew tap |\n\n---\n\n## Releasing\n\nCurrently we release in a semi-automated way:\n\n1. PR & merge an updated\n   [Changelog](https://github.com/PRQL/prql/blob/main/CHANGELOG.md). GitHub will\n   produce a draft version at <https://github.com/PRQL/prql/releases/new>,\n   including \"New Contributors\".\n\n   Use this script to generate a line introducing the enumerated changes:\n\n   ```sh\n   echo \"It has $(git rev-list --count $(git rev-list --tags --max-count=1)..) commits from $(git shortlog --summary $(git rev-list --tags --max-count=1).. | wc -l | tr -d '[:space:]') contributors. Selected changes:\"\n   ```\n\n   When a fix closes an issue reported by someone other than the PR author,\n   thank them in the changelog entry, e.g.\n   `(@pr-author, #5639; reported by @issue-reporter)`.\n\n2. If the current version is correct, then skip ahead. But if the version needs\n   to be changed — for example, we had planned on a patch release, but instead\n   require a minor release — then run\n   `cargo release version $version -x && cargo release replace -x && task prqlc:test-all`\n   to bump the version, and PR the resulting commit.\n\n3. Ensure all changes intended for the release are merged to `main`. Then create\n   the release (which creates the tag on the latest commit on `main`):\n\n   **Web UI:** Go to\n   [Draft a new release](https://github.com/PRQL/prql/releases/new){{footnote: Only\n       maintainers have access to this page.}},\n   copy the changelog entry into the release\n   description{{footnote: Unfortunately GitHub's markdown parser\n        interprets linebreaks as newlines. I haven't found a better way of\n        editing the markdown to look reasonable than manually editing the text\n        or asking LLM to help.}}, enter the tag to be created, and hit\n   \"Publish\".\n\n   **CLI:**\n\n   ```sh\n   gh release create $version --title \"$version\" --notes \"$(cat <<'EOF'\n   <paste changelog entry here>\n   EOF\n   )\"\n   ```\n\n4. From there, both the tag and release is created and all packages are\n   published automatically based on our\n   [release workflow](https://github.com/PRQL/prql/blob/main/.github/workflows/release.yaml).\n\n5. Run\n   `cargo release patch --no-publish --no-push --execute --no-verify --no-confirm --no-tag && task prqlc:test-all`\n   to bump the versions and add a new Changelog section; then PR the resulting\n   commit. Note this currently contains `task prqlc:test-all` to update snapshot\n   tests which contain the version.\n\n<!-- Note we used to have `cargo release version patch -x --no-confirm && cargo release replace -x --no-confirm && task prqlc:test-all`, which was simpler, but in order for `prev_version` to work, we can't separate the `patch` and `replace`, and we need `prev_version` for the prqlc version constraint (search for `prev_version` if unclear). If we moved back to upgrading the tags at the time of release rather than after, we could go back to that. -->\n\n6. Check whether there are [milestones](https://github.com/PRQL/prql/milestones)\n   that need to be pushed out.\n\n7. Review the **Current Status** on the README.md to ensure it reflects the\n   project state.\n\nWe may make this more automated in future; e.g. automatic changelog creation.\n"

This framework manages the interaction with\nPostgreSQL's internal APIs, type conversions, and other function hooks necessary\nto integrate PRQL with PostgreSQL.\n\n## Examples\n\nPL/PRQL functions are defined using the `plprql` language specifier:\n\n```sql\ncreate function match_stats(int) returns table(player text, kd_ratio float) as $$\n  from matches\n  filter match_id == $1\n  group player (\n    aggregate {\n      total_kills = sum kills,\n      total_deaths = sum deaths\n    }\n  )\n  filter total_deaths > 0\n  derive kd_ratio = total_kills / total_deaths\n  select { player, kd_ratio }\n$$ language plprql;\n\nselect * from match_stats(1001)\n\n player  | kd_ratio\n---------+----------\n Player1 |    0.625\n Player2 |      1.6\n(2 rows)\n```\n\nYou can also run PRQL code directly with the `prql` function which is useful for\ncustom SQL in ORMs:\n\n```sql\nselect prql('from matches | filter player == ''Player1''')\nas (id int, match_id int, round int, player text, kills int, deaths int)\nlimit 2;\n\n id | match_id | round | player  | kills | deaths\n----+----------+-------+---------+-------+--------\n  1 |     1001 |     1 | Player1 |     4 |      1\n  3 |     1001 |     2 | Player1 |     1 |      7\n(2 rows)\n\n-- Same as above without the need for the static types, but returns cursor\nselect prql('from matches | filter player == ''Player1''', 'player1_cursor');\nfetch 2 from player1_cursor;\n```\n\n## Getting Started\n\nFor installation instructions and more information on the extension, see the\n[PL/PRQL repository](https://github.com/kaspermarstal/plprql).\n"

The argument to the compiler takes precedence.\n\nFor example, the following shell example specifies `sql.generic` in the query\nand `sql.duckdb` in the `--target` option of the `prqlc compile` command. In\nthis case, `sql.duckdb` takes precedence and the SQL output is based on the\nDuckDB dialect.\n\n```sh\necho 'prql target:sql.generic\n      from foo' | prqlc compile --target sql.duckdb\n```\n\nTo use the target described in the query, a special target `sql.any` can be\nspecified in the compiler option.\n\n```sh\necho 'prql target:sql.generic\n      from foo' | prqlc compile --target sql.any\n```\n\n## Version\n\nPRQL allows specifying a version of the language in the PRQL header, like:\n\n```prql\nprql version:\"0.13.12\"\n\nfrom employees\n```\n\nThis has two roles, one of which is implemented:\n\n- The compiler will raise an error if the compiler is older than the query\n  version. This prevents confusing errors when queries use newer features of the\n  language but the compiler hasn't yet been upgraded.\n- The compiler will compile for the major version of the query. This allows the\n  language to evolve without breaking existing queries, or forcing multiple\n  installations of the compiler. This isn't yet implemented, but is a gating\n  feature for PRQL 1.0.\n\nThe version of the compiler currently in use can be called using the special\nfunction `std.prql.version` in PRQL.\n\n```prql\n[{version = prql.version}]\n```\n\n<!-- prettier-ignore -->\n> [!NOTE]\n> This function was renamed from `std.prql_version` to `prql.version` in\n> PRQL 0.11.1. `std.prql_version` will be removed in PRQL 0.12.0.\n"

This\ncan be quite verbose in SQL.\n\nPRQL offers two approaches — array literals, and a `from_text` transform.\n\n## Array literals\n\nBecause relations (aka a table) in PRQL are just arrays of tuples, they can be\nexpressed with array and tuple syntax:\n\n```prql\nfrom [\n  {a=5, b=false},\n  {a=6, b=true},\n]\nfilter b == true\nselect a\n```\n\n```prql\nlet my_artists = [\n  {artist=\"Miles Davis\"},\n  {artist=\"Marvin Gaye\"},\n  {artist=\"James Brown\"},\n]\n\nfrom artists\njoin my_artists (==artist)\njoin albums (==artist_id)\nselect {artists.artist_id, albums.title}\n```\n\n## `from_text`\n\n`from_text` takes a string in a common format, and converts it to table. It\naccepts a few formats:\n\n- `format:csv` parses CSV (default),\n\n- `format:json` parses either:\n  - an array of objects each of which represents a row, or\n\n  - an object with fields `columns` & `data`, where `columns` take an array of\n    column names and `data` takes an array of arrays.\n\n```prql\nfrom_text \"\"\"\na,b,c\n1,2,3\n4,5,6\n\"\"\"\nderive {\n    d = b + c,\n    answer = 20 * 2 + 2,\n}\n```\n\n```prql\nfrom_text format:json \"\"\"\n[\n    {\"a\": 1, \"m\": \"5\"},\n    {\"a\": 4, \"n\": \"6\"}\n]\n\"\"\"\n```\n\n```prql\nfrom_text format:json \"\"\"\n{\n    \"columns\": [\"a\", \"b\", \"c\"],\n    \"data\": [\n        [1, \"x\", false],\n        [4, \"y\", null]\n    ]\n}\n\"\"\"\n```\n\n## See also\n\n- [How do I: read files?](./read-files.md)\n"

    "content": "# Functions\n\n<!--\nTODOs:\n- Examples are a bit artificial — the interp is just \"divide by 100\" in one case!  -->\n\nFunctions have two types of parameters:\n\n1. Positional parameters, which require an argument.\n2. Named parameters, which optionally take an argument, otherwise using their\n   default value.\n\nSo this function is named `fahrenheit_to_celsius` and has one parameter `temp`:\n\n```prql\nlet fahrenheit_to_celsius = temp -> (temp - 32) / 1.8\n\nfrom cities\nderive temp_c = (fahrenheit_to_celsius temp_f)\n```\n\nThe function below is named `interp`, and has two positional parameters named\n`high` and `x`, and one named parameter named `low` which takes a default\nargument of `0`. It calculates the proportion of the distance that `x` is\nbetween `low` and `high`.\n\n```prql\nlet interp = low:0 high x -> (x - low) / (high - low)\n\nfrom students\nderive {\n  sat_proportion_1 = (interp 1600 sat_score),\n  sat_proportion_2 = (interp low:0 1600 sat_score),\n}\n```\n\n## Other examples\n\n```prql\nlet is_adult = col -> col >= 18\nlet writes_code = col -> (col | in [\"PRQL\", \"Rust\"])\nlet square = col -> (col | math.pow 2)\nlet starts_with_a = col -> (col | text.lower | text.starts_with(\"a\"))\n\nfrom employees\nselect {\n    first_name,\n    last_name,\n    hobby,\n    adult = is_adult age,\n    age_squared = square age,\n}\nfilter ((starts_with_a last_name) && (writes_code hobby))\n```\n\n## Piping values into functions\n\nConsistent with the principles of PRQL, it's possible to pipe values into\nfunctions, which makes composing many functions more readable. When piping a\nvalue into a function, the value is passed as an argument to the final\npositional parameter of the function. Here's the same result as the examples\nabove with an alternative construction:\n\n```prql\nlet interp = low:0 high x -> (x - low) / (high - low)\n\nfrom students\nderive {\n  sat_proportion_1 = (sat_score | interp 1600),\n  sat_proportion_2 = (sat_score | interp low:0 1600),\n}\n```\n\nand\n\n```prql\nlet fahrenheit_to_celsius = temp -> (temp - 32) / 1.8\n\nfrom cities\nderive temp_c = (temp_f | fahrenheit_to_celsius)\n```\n\nWe can combine a chain of functions, which makes logic more readable:\n\n```prql\nlet fahrenheit_to_celsius = temp -> (temp - 32) / 1.8\nlet interp = low:0 high x -> (x - low) / (high - low)\n\nfrom kettles\nderive boiling_proportion = (temp_c | fahrenheit_to_celsius | interp 100)\n```\n\n### Late binding\n\nFunctions can bind to any variable that is in scope when the function is\nexecuted. For example, here `cost_total` refers to the column that's introduced\nin the `from`.\n\n```prql\nlet cost_share = cost -> cost / cost_total\n\nfrom costs\nselect {materials, labor, overhead, cost_total}\nderive {\n  materials_share = (cost_share materials),\n  labor_share = (cost_share labor),\n  overhead_share = (cost_share overhead),\n}\n```\n\n## Partial application\n\nFunctions can be partially applied, which is useful for creating reusable\ntransform wrappers. When a function returns a partially-applied transform, the\nmissing parameters are automatically propagated.\n\nFor example, we can create a `top_n` function that wraps `take`:\n\n```prql\nlet top_n = n -> take n\n\nfrom invoices\ntop_n 10\n```\n\nThis works because `take` requires two arguments (the count and the relation),\nbut `top_n` only provides one. The relation parameter is automatically filled in\nfrom the pipeline.\n\nWe can also compose multiple partial applications:\n\n```prql\nlet top_n = n -> take n\nlet add_constant = x -> derive {constant = x}\n\nlet my_pipeline = (top_n 5 | add_constant 42)\n\nfrom invoices\nmy_pipeline\n```\n\nOr store a fully-configured transform for reuse:\n\n```prql\nlet top_n = n -> take n\nlet top_5 = top_n 5\n\nfrom invoices\ntop_5\n```\n"

This page documents our\n> understanding of the way the final PRQL compiler will likely work. The PRQL\n> compiler currently uses these techniques to compile the `std`, `date`, `text`,\n> and `math` modules into the language.\n>\n> However, at this time (Spring 2024), the `module` facility does not work\n> within a PRQL query itself. That is, a `module` statement in a query cannot\n> import files from the local file system.\n\nDesign goals for **modules**:\n\n1. Allow importing declarations from other files.\n\n2. Have namespaces for things like `std`.\n\n3. Have a hierarchical structure so we can represent files in directories.\n\n4. Have an unambiguous module structure within a project.\n\n## Definition\n\nA module is a namespace that contains declarations. A module is itself a\ndeclaration, which means that it can contain nested child modules.\n\nThis means that modules form a\n[tree graph](<https://en.wikipedia.org/wiki/Tree_(graph_theory)>), which we call\n\"the module structure\".\n\nFor the sake of this document, we will express the module structure with\n`module` keyword and a code block encased in curly braces:\n\n```\nmodule my_playlists {\n    let bangers = ... # a declaration\n\n    module soundtracks {\n        let movie_albums = ... # another declaration\n    }\n}\n```\n\n> The syntax `module name { ...decls... }` is not part of PRQL language, with\n> the objection that it is unnecessary as it only adds more ways of defining\n> modules. If a significant upside of this syntax is found, it may be added in\n> the future.\n\n## Name resolution\n\nAny declarations within a module can be referenced from the outside of the\nmodule:\n\n```prql no-eval\n# using module structure declared above\nmodule my_playlists\n\nlet great_tracks = my_playlists.bangers\n\nlet movie_scores = my_playlists.soundtracks.movie_albums\n```\n\nIdentifiers are resolved relative to current module.\n\n```prql no-eval\nmodule my_playlists {\n    module soundtracks {\n        let movie_albums = (from albums | filter id == 3)\n    }\n\n    from soundtracks.movie_albums\n}\nfrom my_playlists.soundtracks.movie_albums\n```\n\nIf an identifier cannot be resolved relative to the current module, it tries to\nresolve relative to the parent module. This is repeated, stepping up the module\nhierarchy until a match is found or root of the module structure is reached.\n\n```prql no-eval\nmodule my_playlists {\n    let decl_1 = ...\n\n    module soundtracks {\n        let decl_2 = ...\n    }\n\n    module upbeat_rock {\n        let decl_3 = ...\n\n        from decl_1 | join soundtracks.decl2 | join decl_3\n    }\n}\n```\n\n## Main var declaration\n\nThe final variable declaration in a module can omit the leading `let main =` and\nacquire an implicit name main.\n\n```\nmodule my_playlists {\n    let bangers = (from tracks | take 10)\n\n    from playlists | take 10\n}\n\nlet album_titles = my_playlists.main\n```\n\nWhen a module is referenced as a value, the `main` variable is used instead.\nThis is especially useful when referring to a module which is to be compiled to\nRQ (and later SQL).\n\n```\n# last line from previous example could thus be shortened to:\nlet album_titles = my_playlists\n```\n\n## File importing\n\n<!-- prettier-ignore -->\n> [!WARNING]\n> The examples below do **not** work. At this time (Spring 2024), the\n> `module` facility does not work within a PRQL query itself. That is, a\n> `module` statement in a query cannot import files from the local file system.\n\nTo include PRQL source code from other files, we can use the following syntax:\n\n```\nmodule my_playlists\n```\n\nThis loads either `./my_playlists.prql` (a leaf module) or\n`./my_playlists/_my_playlists.prql` (a directory module) and uses its contents\nas module `my_playlists`. If none or both of the files are present, a\ncompilation error is raised.\n\nOnly directory modules can contain module declarations. If a leaf module\ncontains a module declaration, a compilation error is raised, suggesting the\nleaf module to be converted into a directory module. This is a step toward any\nmodule structure having a single \"normalized\" representation in the file system.\nSuch normalization is desired because it restrains the possible file system\nlayouts to a comprehensible and predictable layout, while not sacrificing any\nfunctionality.\n\nDescribed importing rules don't achieve this \"single normalized representation\"\nin full, since any leaf modules could be replaced by a directory module with\nzero submodules, without any semantic changes. Restricting directory modules to\nhave at least one sub-module would not improve approachability enough to justify\nadding this restriction.\n\nFor example, the following module structure is annotated with files names in\nwhich the modules would reside:\n\n```prql no-eval\n\nmodule my_project {\n    # _my_project.prql\n\n    module sales {\n        # sales.prql\n    }\n\n    module projections {\n        # projections/_projections.prql\n\n        module year_2023 {\n            # projections/year_2023.prql\n        }\n\n        module year_2024 {\n            # projections/year_2024.prql\n        }\n    }\n}\n```\n\nIf module `my_project.sales` wants to add a submodule `util`, it has to be\nconverted to a directory modules. This means that it has to be moved to\n`sales/_sales.prql`. The new module would reside in `sales/util.prql`.\n\nThe annotated layout is not the only possible layout for this module structure,\nsince any of the modules `sales`, `year_2023` or `year_2024` could be converted\ninto a directory module with zero sub-modules.\n\nPoint 4 of design goals means that each declaration within a project has a\nsingle fully-qualified name within this project. This is ensured by strict rules\nregarding importing files and the fact that the module structure is a tree.\n\n## Declaration order\n\nThe order of declarations in a module holds no semantic value, except the \"last\n`main` variable\".\n\nReferences between modules can be cyclic.\n\n```\nmodule mod_a {\n    let decl_a_1 = ...\n    let decl_a_2 = (from mod_b.decl_b | take 10)\n}\nmodule mod_b {\n    let decl_b = (from mod_a.decl_a | take 10)\n}\n```\n\nReferences between variable declarations cannot be cyclic.\n\n```\nlet decl_a = (from decl_b)\nlet decl_b = (from decl_a) # error: cyclic reference\n```\n\n```\nmodule mod_a {\n    let decl_a = (from mod_b.decl_b)\n}\nmodule mod_b {\n    let decl_b = (from mod_a.decl_a) # error: cyclic reference\n}\n```\n\n## Compiler interface\n\n`prqlc` provides two interfaces for compiling files.\n\n**Multi-file interface** requires three arguments:\n\n- path to the file containing the module which is the root of the module\n  structure,\n- identifier of the pipeline that should be compiled to RQ (this can also be an\n  identifier of a module that has a `main` pipeline) and,\n- a \"file loader\", which can load files on-demand.\n\nThe path to the root module can be automatically detected by searching for\n`.prql` files starting with `_` in the current working directory.\n\nExample prqlc usage:\n\n```\n$ prqlc compile _project.prql sales.projections.orders_2024\n$ prqlc compile sales.projections.orders_2024\n```\n\n**Single-file interface** requires a single argument; the PRQL source. Any\nattempts to load modules in this mode result in compilation errors. This\ninterface is needed, for example, when integrating the compiler with a database\nconnector (i.e. JDBC) where no other files can be loaded.\n\n## Built-in module structure\n\n> As noted above, this facility is in discussion.\n\n```\n# root module of every project\nmodule project {\n\tmodule std {\n\t\tlet sum = a -> ...\n\t\tlet mean = a -> ...\n\t}\n\n\tmodule default_db {\n\t\t# all inferred tables and defined CTEs\n\t}\n\n\tlet main = (\n\t\tfrom t = tracks\n\t\tselect [track_id, title]\n\t)\n}\n```\n\n## Example\n\n<!-- prettier-ignore -->\n> [!WARNING]\n> The examples below do **not** work. At this time (Spring 2024), the\n> `module` facility does not work within a PRQL query itself. That is, a\n> `module` statement in a query cannot import files from the local file system.\n\nThis is an example project, where each of code block is a separate file.\n\n```\n# _project.prql\n\nmodule employees\nmodule sales\nmodule util\n```\n\n```\n# employees.prql\n\nlet employees = (...)\n\nlet salaries = (...)\n\nlet departments = (...)\n```\n\n```\n# sales/_sales.prql\n\nmodule orders\nmodule projections\n\nlet revenue_by_source = (...)\n```\n\n```\n# sales/orders.prql\n\nlet current_year = (...)\n\nlet archived = (...)\n\nlet by_employee = (from orders | join employees.employees ...)\n```\n\n```\n# sales/projections.prql\n\nlet orders_2023 = (from orders.current_year | append orders.archived)\n\nlet orders_2024 = (...)\n```\n\n```\n# util.prql\n\nlet pretty_print_num = col -> (...)\n```\n\n---\n\nSources:\n\n- [Notes On Module System](https://matklad.github.io/2021/11/27/notes-on-module-system.html),\n  by @matklad.\n"

    "content": "# Name resolution\n\nBecause PRQL primarily handles relational data, it has specialized scoping rules\nfor referencing columns.\n\n## Scopes\n\nIn PRQL's compiler, a scope is the collection of all names one can reference\nfrom a specific point in the program.\n\nIn PRQL, names in the scope are composed from namespace and variable name which\nare separated by a dot, similar to SQL. Namespaces can contain many dots, but\nvariable names cannot.\n\n<!-- prettier-ignore -->\n> [!NOTE]\n> For example, name `my_table.some_column` is a variable `some_column`\n> from namespace `my_table`.\n>\n> Name `foo.bar.baz` is a variable `baz` from namespace `foo.bar`.\n\nWhen processing a query, a scope is maintained and updated for each point in the\nquery.\n\nIt start with only namespace `std`, which is the standard library. It contains\ncommon functions like `sum` or `count`, along with all transform functions such\nas `derive` and `group`.\n\nIn pipelines (or rather in transform functions), scope is also injected with\nnamespaces of tables which may have been referenced with `from` or `join`\ntransforms. These namespaces contain simply all the columns of the table and\npossibly a wildcard variable, which matches any variable (see the algorithm\nbelow). Within transforms, there is also a special namespace that does not have\na name. It is called a _\"frame\"_ and it contains columns of the current table\nthe transform is operating on.\n\n## Resolving\n\nFor each ident we want to resolve, we search the scope's items in order. One of\nthree things can happen:\n\n- Scope contains an exact match, e.g. a name that matches in namespace and the\n  variable name.\n\n- Scope does not contain an exact match, but the ident did not specify a\n  namespace, so we can match a namespace that contains a `*` wildcard. If\n  there's a single namespace, the matched namespace is also updated to contain\n  this new variable name.\n\n- Otherwise, the nothing is matched and an error is raised.\n\n## Translating to SQL\n\nWhen translating into an SQL statement which references only one table, there is\nno need to reference column names with table prefix.\n\n```prql\nfrom employees\nselect first_name\n```\n\nBut when there are multiple tables and we don't have complete knowledge of all\ntable columns, a column without a prefix (i.e. `first_name`) may actually reside\nin multiple tables. Because of this, we have to use table prefixes for all\ncolumn names.\n\n```prql\nfrom employees\nderive {first_name, dept_id}\njoin d=departments (==dept_id)\nselect {first_name, d.title}\n```\n\nAs you can see, `employees.first_name` now needs table prefix, to prevent\nconflicts with potential column with the same name in `departments` table.\nSimilarly, `d.title` needs the table prefix.\n"

    "path": "web/book/src/reference/spec/type-system.md",
    "content": "# Type system\n\n> Status: under development\n\n> The type system determines the allowed values of a term.\n\n## Purpose\n\nEach of the SQL DBMSs has their own type system. Thanks to the SQL standard,\nthey are very similar, but have key differences regardless. For example, SQLite\ndoes not have a type for date or time or timestamps, but it has functions for\nhandling date and time that take ISO 8601 strings or integers that represent\nUnix timestamps. So it does support most of what is possible to do with dates in\nother dialects, even though it stores data with a different physical layout and\nuses different functions to achieve that.\n\nPRQL's task is to define it's own description of _data formats_, just as how it\nalready defines common _data transformations_.\n\nThis is done in two steps:\n\n1. Define PRQL's Type System (PTS), following principles we think a relational\n   language should have (and not fixate on what existing SQL DBMSs have).\n\n2. Define a mapping between SQL Type System (STS) and PTS, for each of the\n   DBMSs. Ideally we'd want that to be a bijection, so each type in PTS would be\n   represented by a single type in STS and vice-versa. Unfortunately this is not\n   entirely possible, as shown below.\n\nIn practical terms, we want for a user to be able to:\n\n- ... express types of their database with PRQL (map their STS into PTS). In\n  some cases, we can allow to say \"your database is not representable with PRQL,\n  change it or use only a subset of it\". An example of what we don't want to\n  support are arrays with arbitrary indexes in Postgres (i.e. 2-based index for\n  arrays).\n\n  This task of mapping to PTS could be automated by LSP server, by introspecting\n  user's SQL database and generating PRQL source.\n\n- ... express their SQL queries in PRQL. Again, using mapping from STS to PTS,\n  one should be able to express any SQL operation in PRQL.\n\n  For example, translate MSSQL `DATEDIFF` to subtraction operator `-` in PRQL.\n\n  For now, this mapping is manual, but should be documented and may be\n  automated.\n\n- ... use any PRQL feature in their database. Here we are mapping from PTS into\n  an arbitrary STS.\n\n  For example, translate PRQL's datetime operations to use TEXT in SQLite.\n\n  As of now, prqlc already does a good job of automatically doing this mapping.\n\nExample of the mapping between PTS and two STSs:\n\n| PTS       | STS Postgres | STS SQLite |\n| --------- | ------------ | ---------- |\n| int32     | integer      | INTEGER    |\n| int64     | bigint       | INTEGER    |\n| timestamp | timestamp    | TEXT       |\n\n## Principles\n\n**Algebraic types** - have a way of expressing sum and product types. In Rust,\nsum would be an enum and product would be tuple or a struct. In SQL, product\nwould be a row, since it can contain different types, all at once. Sum would be\nharder to express, see\n[this post](https://www.parsonsmatt.org/2019/03/19/sum_types_in_sql.html).\n\nThe value proposition here is that algebraic types give a lot modeling\nflexibility, all while being conceptually simple.\n\n**Composable** - as with transformation, we'd want types to compose together.\n\nUsing Python, JavaScript, C++ or Rust, one could define many different data\nstructures that would correspond to our idea of \"relation\". Most of them would\nbe an object/struct that has column names and types and then a generic array of\narrays for rows.\n\nPRQL's type system should also be able to express relations as composed from\nprimitive types, but have only one idiomatic way of doing so.\n\nIn practice, this means that builtin types include only primitives (int, text,\nbool, float), tuple (for product), enum (for sum) and array (for repeating). An\nSQL row translates to a tuple, and a relation translates to an array of tuples.\n\nComposability also leads to a minimal type system, which does not differentiate\nbetween tuples, objects and structs. A single product type is enough.\n\n**No subtyping** - avoid super types and inheritance.\n\nSubtyping is a natural extension to a type system, where a type can be a super\ntype of some other type. This is base mechanism for Object Oriented Programming,\nbut is also present in most dynamically types languages. For example, a type\n`number` might be super type of `int` and `float`.\n\nPTS does not have subtyping, because it requires dynamic dispatch and because it\nadds unnecessary complexity to generic type arguments.\n\nDynamic dispatch, is a mechanism that would be able, for example, to call\nappropriate `to_string` function for each element of an array of `number`. This\narray contains both elements of type `int` and type `float`, with different\n`to_string` implementations.\n\n<!--\n> This segment was part of initial type system proposal.\n> I still do believe it would be useful and possible to implement,\n> but it should be updated to latest TS changes.\n\n**Type constraints** - constrain a type with a predicate. For example, have a\ntype of `int64`s that are equal or greater than 10. Postgres\n[does support this](https://news.ycombinator.com/item?id=34835063). The primary\nvalue of using constrained types would not be validation (as it is used in\nlinked article), but when matching the type.\n\nSay, for example, that we have a pipeline like this:\n\n```\nderive color = switch [x => 'red', true => 'green']\nderive is_red = switch [color == 'red' => true, color == 'green' => false]\n```\n\nIt should be possible to infer that `color` is of type `text`, but only when\nequal to `'red'` or `'green'`. This means that the second switch covers all\npossible cases and `is_red` cannot be `null`.\n-->\n\n## Definition\n\n> For any undefined terms used in this section, refer to set theory and\n> mathematical definitions in general.\n\nA \"type of a variable\" is a \"set of all possible values of that variable\".\n\n### Primitives\n\nAt the moment of writing, PRQL defines following primitive types: `int`,\n`float`, `bool`, `text`, `date`, `time` and `timestamp`. New primitive types\nwill be added in the future and some of existing types might be split into\nsmaller subsets (see section \"Splitting primitives\").\n\n### Tuples\n\nTuple type is a product type.\n\nIt contains n ordered fields, where n is known at compile-time. Each field has a\ntype itself and an optional name. Fields are not necessarily of the same type.\n\nIn other languages, similar constructs are named record, struct, tuple, named\ntuple or (data)class.\n\n```\ntype my_row = {id = int, bool, name = str}\n```\n\n### Arrays\n\nArray is a container type that contains n ordered fields, where n is not known\nat compile-time. All fields are of the same type and cannot be named.\n\n```\ntype array_of_int = [int]\n```\n\n### Functions\n\n```\ntype floor_signature = func float -> int\n```\n\n### Union\n\n```\ntype status = (\n  paid = () ||\n  unpaid = float ||\n  {reason = text, cancelled_at = timestamp} ||\n)\n```\n\nThis is \"a sum type\".\n\n## Type annotations\n\nVariable annotations and function parameters may specify type annotations:\n\n```\nlet a <t> = x\n```\n\nThe value of `x` (and thus `a`) must be an element of `t`.\n\n```\nlet my_func = func x <t> -> y\n```\n\nThe value of argument supplied to `x` must be an element of `t`.\n\n```\nlet my_func = func x -> <t> y\n```\n\nThe value of function body `y` must be an element of `t`.\n\n## Physical layout\n\n_Logical type_ is user-facing the notion of a type that is the building block of\nthe type system.\n\n_Physical layout_ is the underlying memory layout of the data represented by a\nvariable.\n\nIn many programming languages, physical layout of a logical type is dependent on\nthe target platform. Similarly, physical layout of a PRQL logical type is\ndependent on representation of that type in the target STS.\n\n```\nPTS logical type  --->  STS logical type  ---> STS physical layout\n```\n\nNote that not all STS types do not have a single physical layout. Postgres has a\nlogical (pseudo)type `anyelement`, which is a super type of any data type. It\ncan be used as a function parameter type, but does not have a single physical\nlayout so it cannot be used in a column declaration.\n\nFor now, PRQL does not define physical layouts of any type. It is not needed\nsince PRQL is not used for DDL (see section \"Splitting primitives\") or does not\nsupport raw access to underlying memory.\n\nAs a consequence, results of a PRQL query cannot be robustly compared across\nDBMSs, since the physical layout of the result will vary.\n\nIn the future, PRQL may define a common physical layout of types, probably using\nApache Arrow.\n\n## Examples\n\n```\ntype my_relation = [{\n\tid = int,\n\ttitle = text,\n\tage = int\n}]\n\ntype invoices = [{\n    invoice_id = int64,\n    issued_at = timestamp,\n    labels = [text]\n\n    #[repr(json)]\n    items = [{\n        article_id = int64,\n        count = int16 where x -> x >= 1,\n    }],\n    paid_by_user_id = (int64 || null),\n}]\n```\n\n## Appendix\n\n### Splitting primitives\n\nThis document mentions `int32` and `int64` as distinct types, but there is no\nneed for that in the initial implementation. The built-in `int` can associate\nwith all operations on integers and translate PRQL to valid SQL regardless of\nthe size of the integer. Later, `int` cam be replaced by `int8`, `int16`,\n`int32`, `int64`.\n\nThe general rule for \"when to make a distinction between types\" would be \"as\nsoon as the types carry different information and we find an operation that\nwould be expressed differently\". In this example, that would require some\noperation on `int32` to have different syntax than same operation over `int64`.\n\nWe can have such relaxed rule because PRQL is not aiming to be a Data Definition\nLanguage and does not have to bother with exact physical layout of types.\n\n### Type representations\n\nThere are cases where a PTS type has multiple possible and valid representations\nin some STSs.\n\nFor such cases, we'd want to support the use of alternative representations for\nstoring data, but also application of any function that is defined for the\noriginal type.\n\nUsing SQLite as an example again, users may have some temporal data stored as\nINTEGER unix timestamp and some as TEXT that contains ISO 8601 without timezone.\nFrom the user's perspective, both of these types are `timestamp`s and should be\ndeclared as such. But when compiling operations over these types to SQL, the\ncompiler should consider their different representations in STS. For example a\ndifference between two timestamps `timestamp - timestamp` can be translated to a\nnormal int subtraction for INTEGER repr, but must apply SQLite's function\n`unixepoch` when dealing with TEXT repr.\n\nTable declarations should therefore support annotations that give hints about\nwhich representation is used:\n\n```\ntable foo {\n    #[repr(text)]\n    created_at: timestamp,\n}\n```\n\nA similar example is an \"array of strings type\" in PTS that could be represented\nby a `text[]` (if DBMS supports arrays) or `json` or it's variant `jsonb` in\nPostgres. Again, the representation would affect operators: in Postgres, arrays\nwould be accessed with `my_array[1]` and json arrays would use\n`my_json_array -> 1`. This example may not be applicable, if we decide that we\nwant a separate JSON type in PST.\n\n### RQ functions, targets and reprs\n\n> This part is talks about technical implementations, not the language itself\n\n#### Idea\n\nRQ contains a single node kind for expressing operations and functions:\nBuiltInFunction (may be renamed in the future).\n\nIt is a bottleneck that we can leverage when trying to affect how an operator or\na function interacts with different type representations on different targets.\n\nIdea is to implement the BuiltInFunction multiple times and annotate it with it\nintended target and parameter representation. Then we can teach the compiler to\npick the appropriate function implementation that suit current repr and\ncompilation target.\n\n#### Specifics\n\nRQ specification is an interface that contains functions, identified by name\n(i.e. `std.int8.add`). These functions have typed parameters and a return value.\nIf an RQ function call does not match the function declaration in number or in\ntypes of the parameters, this is considered an invalid RQ AST.\n\nWe provide multiple implementations for each RQ function. They are annotated\nwith a target (i.e. `#[target(sql.sqlite)]`) and have their params annotated\nwith type reprs (i.e. `#[repr(int)]`).\n\n```\n# using a made-up syntax\n\n#[target(sql.sqlite)]\nfunc std.int8.add\n    #[repr(int8)] x\n    #[repr(int8)] y\n    -> s\"{x} + {y}\"\n```\n\nEach RQ type has one canonical repr that serves as the reference implementation\nfor other reprs and indicates the amount of contained data (i.e. 1 bit, 8 bits,\n64 bits).\n\n#### Example\n\nLet's say for example, that we'd want to support 8bit integer arithmetic, and\nthat we'd want the result of `127 + 1` to be `-128` (ideally we'd handle this\nbetter, but bear with me for the sake of the example). Because some RDBMSs don't\nsupport 8bit numbers and do all their integer computation with 64bit numbers\n(SQLite), we need to implement an alternative type representation for that\ntarget.\n\nThe logical type `int8` could have the following two reprs:\n\n- canonical `repr_int8` that contains 8 bits in two's complement, covering\n  integer values in range -128 to 127 (inclusive),\n- `repr_int64` that contains 64 bits of data, but is using only the values that\n  are also covered by `repr_int8`.\n\nNow we'd implement function `std.int8.add` for each of the reprs. Let's assume\nthat the `int8` implementation is straightforward and that databases don't just\nchange the data type when a number overflows. The impl for `int64` requires a\nCASE statement that checks if the value would overflow and subtact 256 in that\ncase.\n\nThe goal here is that the results of the two impls are equivalent. To validate\nthat, we also need a way to convert between the reprs, or another `to_string`\nfunction, implemented for both reprs.\n"

It supports two\n  additional features:\n  - _Names [`this` & `that`](../../syntax/keywords.md#this--that)_: Along name\n    `this`, which refers to the first input relation, `condition` can use name\n    `that`, which refers to the second input relation.\n  - _Self equality operator_: If the condition is an equality comparison between\n    two columns with the same name (i.e. `(this.col == that.col)`), it can be\n    expressed with only `(==col)`.\n\n## Examples\n\n```prql\nfrom employees\njoin side:left positions (employees.id==positions.employee_id)\n```\n\n---\n\n```prql\nfrom employees\njoin side:left p=positions (employees.id==p.employee_id)\n```\n\n---\n\n```prql\nfrom tracks\njoin side:left artists (\n  # This adds a `country` condition, as an alternative to filtering\n  artists.id==tracks.artist_id && artists.country=='UK'\n)\n```\n\n---\n\nIn SQL, CROSS JOIN is a join that returns each row from first relation matched\nwith all rows from the second relation. To accomplish this, we can use condition\n`true`, which will return all rows of the cartesian product of the input\nrelations:\n\n```\nfrom shirts\njoin hats true\n```\n\n---\n\n[`this` & `that`](../../syntax/keywords.md#this--that) can be used to refer to\nthe current & other table respectively:\n\n```prql\nfrom tracks\njoin side:inner artists (\n  this.id==that.artist_id\n)\n```\n\n---\n\nIf the join conditions are of form `left.x == right.x`, we can use \"self\nequality operator\":\n\n```prql\nfrom employees\njoin positions (==emp_no)\n```\n"

This can operate in two ways:\n\n- We use `SELECT * EXCLUDE` / `SELECT * EXCEPT` for the columns supplied to\n  `select !{}` in dialects which support it.\n- Otherwise, the columns must have been defined prior in the query (unless all\n  of a table's columns are excluded); for example in another `select` or a\n  `group` transform. In this case, we evaluate and specify the columns that\n  should be included in the output SQL.\n\nSome examples:\n\n```prql\nprql target:sql.bigquery\nfrom tracks\nselect !{milliseconds, bytes}\n```\n\n```prql\nfrom tracks\nselect {track_id, title, composer, bytes}\nselect !{title, composer}\n```\n\n```prql\nfrom artists\nderive nick = name\nselect !{artists.*}\n```\n\nNote that `!` is also the `NOT` operator, so without the tuple it has a\ndifferent meaning:\n\n```prql\nprql target:sql.bigquery\nfrom tracks\nselect !is_compilation\n```\n"

(Otherwise, `sort -foo` is parsed as a subtraction between `sort`\n  and `foo`.)\n\n## Examples\n\n```prql\nfrom employees\nsort age\n```\n\n```prql\nfrom employees\nsort {-age}\n```\n\n```prql\nfrom employees\nsort {age, -tenure, +salary}\n```\n\nWe can also use expressions:\n\n```prql\nfrom employees\nsort {s\"substr({first_name}, 2, 5)\"}\n```\n\n## Ordering guarantees\n\nOrdering is persistent through a pipeline in PRQL. For example:\n\n```prql\nfrom employees\nsort tenure\njoin locations (==employee_id)\n```\n\nHere, PRQL pushes the `sort` down the pipeline, compiling the `ORDER BY` to the\n_end_ of the query. Consequently, most relation transforms retain the row order.\n\nThe explicit semantics are:\n\n- `sort` introduces a new order,\n- `group` resets the order,\n- `join` retains the order of the left relation,\n- database tables don't have a known order.\n\nComparatively, in SQL, relations possess no order, being orderable solely within\nthe context of the query result, `LIMIT` statement, or window function. The lack\nof inherent order can result in an unexpected reshuffling of a previously\nordered relation from a `JOIN` or windowing operation.\n\n<!-- prettier-ignore -->\n> [!NOTE]\n> To be precise — in PRQL, a relation is an _array of tuples_ and not a\n> set or a bag. The persistent nature of this order remains intact through\n> sub-queries and intermediate table definitions.\n\nFor instance, an SQL query such as:\n\n```sql\nWITH albums_sorted AS (\n  SELECT *\n  FROM albums\n  ORDER BY title\n)\nSELECT *\nFROM albums_sorted\nJOIN artists USING (artist_id)\n```\n\n...doesn't guarantee any row order (indeed — even without the `JOIN`, the SQL\nstandard doesn't guarantee an order, although most implementations will respect\nit).\n\n<!-- We rolling this back. Waiting on the outcome of https://github.com/PRQL/prql/issues/2622 -->\n\n<!-- ## Nulls\n\nPRQL defaults to `NULLS LAST` when compiling to SQL. Because databases have\ndifferent defaults, the compiler emits this for all targets for which it's not a\ndefault{{footnote: except for MSSQL, which doesn't support this}}.\n\nThe main benefit of this approach is that `take 42` will select non-null values\nfor both ascending and descending sorts, which is generally what is wanted.\n\nThere isn't currently a way to change this for a query, but if that would be\nhelpful, please raise an issue.\n\nNote how DuckDB doesn't require a `NULLS LAST`, unlike the generic targets\nabove:\n\n```prql\nprql target:sql.duckdb\n\nfrom artists\nsort artist_id\ntake 42\n```\n\n```admonish info\nCheck out [DuckDB #7174](https://github.com/duckdb/duckdb/pull/7174) for a survey of various databases' implementations.\n``` -->\n"

It consists of the function name followed by arguments separated by\nwhitespace.\n\n```prql no-eval\nfunction_name arg1 arg2 arg3\n```\n\nIf one of the arguments is also a function call, it must be encased in\nparentheses, so we know where arguments of inner function end and the arguments\nof outer function start.\n\n```prql no-eval\nouter_func arg_1 (inner_func arg_a, arg_b) arg_2\n```\n\nThe function name must refer to a function variable, which has either\n[been declared](../declarations/functions.md) in the\n[standard library](../stdlib/) or some other module.\n\nFunction calls can also specify named parameters using `:` notation:\n\n```prql no-eval\nfunction_name arg1 named_param:arg2 arg3\n```\n\n## Pipeline\n\nThere is a alternative way of calling functions: using a pipeline. Regardless of\nwhether the pipeline is delimited by pipe symbol `|` or a new line, the pipeline\nis equivalent to applying each of functions as the last argument of the next\nfunction.\n\n```prql no-eval\na | foo 3 | bar 'hello' 'world' | baz\n```\n\n... is equivalent to ...\n\n```prql no-eval\nbaz (bar 'hello' 'world' (foo 3 a))\n```\n\n<!--\nTODO: this should be a part of the tutorial\n\n\nAs you may have noticed, transforms are regular functions too!\n\n```prql\nfrom employees\nfilter age > 50\nsort name\n```\n\n... is equivalent to ...\n\n```prql\nfrom employees | filter age > 50 | sort name\n```\n\n... is equivalent to ...\n\n```prql\nfilter age > 50 (from employees) | sort name\n```\n\n... is equivalent to ...\n\n```prql\nsort name (filter age > 50 (from employees))\n```\n\nAs you can see, the first example with pipeline notation is much easier to\ncomprehend, compared to the last one with the regular function call notation.\nThis is why it is recommended to use pipelines for nested function calls that\nare 3 or more levels deep.\n\n-->\n"

For example, currently\nusing a bare `time` as a column name will fail, because it's also a type:\n\n```prql error no-fmt\nfrom invoices\nderive t = time\n```\n\nBut with `this.time`, we can remove the ambiguity:\n\n```prql\nfrom invoices\nderive t = this.time\n```\n\n## Quoting\n\nTo use characters that would be otherwise invalid, identifiers can be surrounded\nby with backticks.\n\nWhen compiling to SQL, these identifiers will use dialect-specific quotes and\nquoting rules.\n\n```prql\nprql target:sql.mysql\nfrom employees\nselect `first name`\n```\n\n```prql\nprql target:sql.postgres\nfrom employees\nselect `first name`\n```\n\n```prql\nprql target:sql.bigquery\n\nfrom `project-foo.dataset.table`\njoin `project-bar.dataset.table` (==col_bax)\n```\n\n## Schemas & database names\n\nIdentifiers of database tables can be prefixed with schema and databases names.\n\n```prql\nfrom my_database.chinook.albums\n```\n\nNote that all of following identifiers will be treated as separate table\ndefinitions: `tracks`, `public.tracks`, `my_database.public.tracks`.\n\n## Keywords\n\nPRQL uses following keywords:\n\n- **`prql`** - query header [_more..._](../../project/target.md)\n- **`let`** - variable definition [_more..._](../declarations/variables.md)\n- **`into`** - variable definition [_more..._](../declarations/variables.md)\n- **`case`** - flow control [_more..._](../syntax/case.md)\n- **`type`** - type declaration\n- **`func`** - explicit function declaration\n  [_more..._](../declarations/functions.md)\n- **`module`** - used internally\n- **`internal`** - used internally\n- **`true`** - boolean [_more..._](./literals.md#booleans)\n- **`false`** - boolean [_more..._](./literals.md#booleans)\n- **`null`** - NULL [_more..._](./literals.md#null)\n\nKeywords can be used as identifiers (of columns or variables) when encased in\nbackticks: `` `case` ``.\n\nTransforms are normal functions within the `std` namespace, not keywords.

For example, a Python\nf-string of `f\"average({col})\"` would produce `\"average(salary)\"`, with quotes;\nwhile in PRQL, `s\"average({col})\"` produces `average(salary)`, without quotes.\n\nNote that interpolations can only contain plain variable names and not whole\nexpression like Python.\n\nWe can also use s-strings to produce a full table:\n\n```prql\nfrom s\"SELECT DISTINCT ON first_name, id, age FROM employees ORDER BY age ASC\"\njoin s = s\"SELECT * FROM salaries\" (==id)\n```\n\n<!-- prettier-ignore -->\n> [!NOTE]\n> S-strings in user code are intended as an escape hatch for an\n> unimplemented feature. If we often need s-strings to express something, that's\n> a sign we should implement it in PRQL or PRQL's stdlib. If you often require\n> an s-string,\n> [submit an issue with your use case](https://github.com/PRQL/prql/issues/new/choose).\n\n## Braces\n\nTo output braces from an s-string, use double braces:\n\n```prql\nfrom employees\nderive {\n  has_valid_title = s\"regexp_contains(title, '([a-z0-9]*-){{2,}}')\"\n}\n```\n\n## Precedence within s-strings\n\nVariables in s-strings are inserted into the SQL source as-is, which means we\nmay get surprising behavior when the variable has multiple terms and the\ns-string isn't parenthesized.\n\nIn this toy example, the expression `salary + benefits / 365` gets precedence\nwrong. The generated SQL code is as if we had written\n`salary + (benefits / 365)`.\n\n```prql\nfrom employees\nderive {\n  gross_salary = salary + benefits,\n  daily_rate = s\"{gross_salary} / 365\"\n}\n```\n\nInstead, the numerator `{gross_salary}` must be encased in parentheses:\n\n```prql\nfrom employees\nderive {\n  gross_salary = salary + benefits,\n  daily_rate = s\"({gross_salary}) / 365\"\n}\n```\n"

    "content": "# Aggregation\n\nA key feature of analytics is reducing many values down to a summary. This act\nis called \"aggregation\" and always includes a function &mdash; for example,\n`average` or `sum` &mdash; that reduces values in the table to a single row.\n\n### `aggregate` transform\n\nThe `aggregate` transform takes a tuple to create one or more new columns that\n\"distill down\" data from all the rows.\n\n```prql no-eval\nfrom invoices\naggregate { sum_of_orders = sum total }\n```\n\nThe query above computes the sum of the `total` column of all rows of the\n`invoices` table to produce a single value.\n\n`aggregate` can produce multiple summaries at once when one or more aggregation\nexpressions are contained in a tuple. `aggregate` discards all columns that are\nnot present in the tuple.\n\n```prql no-eval\nfrom invoices\naggregate {\n    num_orders = count this,\n    sum_of_orders = sum total,\n}\n```\n\nIn the example above, the result is a single row with two columns. The `count`\nfunction displays the number of rows in the table that was passed in; the `sum`\nfunction adds up the values of the `total` column of all rows.\n\n## Grouping\n\nSuppose we want to produce summaries of invoices _for each city_ in the table.\nWe could create a query for each city, and aggregate its rows:\n\n```prql no-eval\nfrom invoices\nfilter billing_city == \"Oslo\"\naggregate { sum_of_orders = sum total }\n```\n\nBut we would need to do it for each city: `London`, `Frankfurt`, etc. Of course\nthis is repetitive (and boring) and error prone (because we would need to type\neach `billing_city` by hand). Moreover, we would need to create a list of each\n`billing_city` before we started.\n\n### `group` transform\n\nThe `group` transform separates the table into groups (say, those having the\nsame city) using information that's already in the table. It then applies a\ntransform to each group, and combines the results back together:\n\n```prql no-eval\nfrom invoices\ngroup billing_city (\n    aggregate {\n        num_orders = count this,\n        sum_of_orders = sum total,\n    }\n)\n```\n\nThose familiar with SQL have probably noticed that we just decoupled aggregation\nfrom grouping.\n\nAlthough these operations are connected in SQL, PRQL makes it straightforward to\nuse `group` and `aggregate` separate from each other, while combining with other\ntransform functions, such as:\n\n```prql no-eval\nfrom invoices\ngroup billing_city (\n    take 2\n)\n```\n\nThis code collects the first two rows for each city's `group`.\n"

    "path": "web/book/src/tutorial/relations.md",
    "content": "# Relations\n\nPRQL is designed on top of _relational algebra_, which is the established data\nmodel used by modern SQL databases. A _relation_ has a rigid mathematical\ndefinition, which can be simplified to \"a table of data\". For example, the\n`invoices` table from the Chinook database\n([https://github.com/lerocha/chinook-database](https://github.com/lerocha/chinook-database))\nlooks like this:\n\n| invoice_id | customer_id | billing_city | _other columns_ | total |\n| ---------- | ----------- | ------------ | :-------------: | ----- |\n| 1          | 2           | Stuttgart    |       ...       | 1.98  |\n| 2          | 4           | Oslo         |       ...       | 3.96  |\n| 3          | 8           | Brussels     |       ...       | 5.94  |\n| 4          | 14          | Edmonton     |       ...       | 8.91  |\n| 5          | 23          | Boston       |       ...       | 13.86 |\n| 6          | 37          | Frankfurt    |       ...       | 0.99  |\n\nA relation is composed of rows. Each row in a relation contains a value for each\nof the relation's columns. Each column in a relation has a unique name and a\ndesignated data type. The table above is a relation, and has columns named\n`invoice_id`and `customer_id` each with a data type of \"integer number\", a\n`billing_city` column with a data type of \"text\", several other columns, and a\n`total` column that contains floating-point numbers.\n\n## Queries\n\nThe main purpose of PRQL is to build queries that combine and transform data\nfrom relations such as the `invoices` table above. Here is the most basic query:\n\n```prql no-eval\nfrom invoices\n```\n\n<!-- prettier-ignore -->\n> [!NOTE]\n> Try each of these examples here in the\n> [Playground.](https://prql-lang.org/playground/) Enter the query on the\n> left-hand side, and click the **Query Results** tab on the right-hand side to\n> see the result.\n\nThe result of the query above is not terribly interesting, it's just the same\nrelation as before.\n\n### `select` transform\n\nThe `select` function picks the columns to pass through based on a list and\ndiscards all others. Formally, that list is a _tuple_ of comma-separated\nexpressions wrapped in `{ ... }`.\n\nSuppose we only need the `order_id` and `total` columns. Use `select` to choose\nthe columns to pass through. _(Try it in the\n[Playground.](https://prql-lang.org/playground/))_\n\n```prql no-eval\nfrom invoices\nselect { order_id, total }\n```\n\nWe can write the items in the tuple on one or several lines: trailing commas are\nignored. In addition, we can assign any of the expressions to a _variable_ that\nbecomes the name of the resulting column in the SQL output.\n\n```prql no-eval\nfrom invoices\nselect {\n  OrderID = invoice_id,\n  Total = total,\n}\n```\n\nThis is the same query as above, rewritten on multiple lines, and assigning\n`OrderID` and `Total` names to the columns.\n\nOnce we `select` certain columns, subsequent transforms will have access only to\nthose columns named in the tuple.\n\n### `derive` transform\n\nTo add columns to a relation, we can use the `derive` function. Let's define a\nnew column for Value Added Tax, set at 19% of the invoice total.\n\n```prql no-eval\nfrom invoices\nderive { VAT = total * 0.19 }\n```\n\n<!-- todo: make sure that the new column is unnamed -->\n\nThe value of the new column can be a constant (such as a number or a string), or\ncan be computed from the value of an existing column. Note that the value of the\nnew column is assigned the name `VAT`.\n\n### `join` transform\n\nThe `join` transform also adds columns to the relation by combining the rows\nfrom two relations \"side by side\". To determine which rows from each relation\nshould be joined, `join` has match criteria, written in `( ... )`.\n\n```prql no-eval\nfrom invoices\njoin customers ( ==customer_id )\n```\n\nThis example \"connects\" the customer information from the `customers` relation\nwith the information from the `invoices` relation, using identical values of the\n`customer_id` column from each relation to match the rows.\n\nIt is frequently useful to assign an alias to both relations being joined\ntogether so that each relation's columns can be referred to uniquely.\n\n```prql no-eval\nfrom inv=invoices\njoin cust=customers ( ==customer_id )\n```\n\nIn the example above, the alias `inv` represents the `invoices` relation and\n`cust` represents the `customers` relation. It then becomes possible to refer to\n`inv.billing_city` and `cust.last_name` unambiguously.\n\n### Summary\n\nPRQL manipulates relations (tables) of data. The `derive`, `select`, and `join`\ntransforms change the number of columns in a table. The first two never affect\nthe number of rows in a table. `join` may change the number of rows, depending\non the chosen type of join.\n\nThis final example combines the above into a single query. It illustrates _a\npipeline_ - the fundamental basis of PRQL. We simply add new lines (transforms)\nat the end of the query. Each transform modifies the relation produced by the\nstatement above to produce the desired result.\n\n```prql no-eval\nfrom inv=invoices\njoin cust=customers (==customer_id)\nderive { VAT = inv.total * 0.19 }\nselect {\n  OrderID = inv.invoice_id,\n  CustomerName = cust.last_name,\n  Total = inv.total,\n  VAT,\n}\n```\n\n<!-- PRQL uses the data from... _Where does our data come from? Do we use some canonical version?_ -->\n"

    "content": "---\ntitle: \"FAQ\"\n---\n\nHere are some of the most common questions we hear. Have something else you'd\nlike to ask? Pop by our [Discord](https://discord.com/invite/eQcfaCmsNc) and ask\naway!\n\n{{< faq \"Cool story Hansel, but what can I actually do with PRQL _now_?\" >}}\n\nPRQL is ready to use by the intrepid, either with our supported integrations, or\nwithin your own tools, using one of our supported language bindings. The easiest\nway is with our integrations:\n\n- **Prototype your PRQL queries** in the\n  [Playground](https://prql-lang.org/playground/) or the\n  [VS Code extension](https://marketplace.visualstudio.com/items?itemName=PRQL-lang.prql-vscode)\n  and copy/paste the resulting SQL into your database. It's not the perfect\n  workflow, but it's easy to get started.\n- **[Jupyter](https://pyprql.readthedocs.io/en/latest/magic_readme.html)**\n  allows writing PRQL in a Jupyter notebook or IPython repl, with a `%%prql`\n  magic. As well as connecting to existing DBs, our integration with DuckDB\n  enables querying pandas dataframes, CSVs & Parquet files, and writing the\n  output to a dataframe.\n- **[DuckDB extension](https://github.com/ywelsch/duckdb-prql)** — is a DuckDB\n  extension which allows querying a DuckDB instance with PRQL.\n\nIt's also possible to query PRQL from your code with our [bindings](/#bindings)\nfor R, Rust, Python & JS. For an example of using PRQL with DuckDB, check out\n[Querying with PRQL](https://eitsupi.github.io/querying-with-prql/).\n\n{{</ faq >}}\n\n{{< faq \"Something here reminds me of another project, did you take the idea from them?\" >}}\n\nYes, probably. We're standing on the shoulders of giants:\n\n- [dplyr](https://dplyr.tidyverse.org/) is a beautiful language for manipulating\n  data, in R. It's very similar to PRQL. It only works on in-memory R data.\n  - There's also [dbplyr](https://dbplyr.tidyverse.org/) which compiles a subset\n    of dplyr to SQL, though requires an R runtime.\n- [Kusto](https://learn.microsoft.com/en-us/kusto/query/tutorials/learn-common-operators?view=azure-data-explorer&preserve-view=true&pivots=azuredataexplorer)\n  is also a beautiful pipelined language, similar to PRQL. But it can only use\n  Kusto-compatible DBs.\n  <!-- We can add more articles by linking from works in the \"There are other similar piecs out there\" sentence -->\n- [Against SQL](https://www.scattered-thoughts.net/writing/against-sql/) gives a\n  fairly complete description of SQL's weaknesses, both for analytical and\n  transactional queries. [**@jamii**](https://github.com/jamii) consistently\n  writes insightful pieces, and it's worth sponsoring him for his updates. There\n  are\n  [other](https://buttondown.email/jaffray/archive/sql-scoping-is-surprisingly-subtle-and-semantic/)\n  similar pieces out there.\n- Julia's [DataPipes.jl](https://gitlab.com/aplavin/DataPipes.jl) &\n  [Chain.jl](https://github.com/jkrumbiegel/Chain.jl) demonstrate how effective\n  point-free pipelines can be, and how line breaks can work as pipes.\n- [OCaml](https://ocaml.org/)'s elegant and simple syntax serves as inspiration.\n\nAnd there are many projects similar to PRQL:\n\n- [Ecto](https://hexdocs.pm/ecto/Ecto.html#module-query) is a sophisticated ORM\n  library in Elixir which has pipelined queries as well as more traditional ORM\n  features.\n- [Morel](https://www.thestrangeloop.com/2021/morel-a-functional-query-language.html)\n  is a functional language for data, also with a pipeline concept. It doesn't\n  compile to SQL but states that it can access external data.\n- [Malloy](https://github.com/looker-open-source/malloy) from Looker &\n  [**@lloydtabb**](https://github.com/lloydtabb) in a new language which\n  combines a declarative syntax for querying with a modelling layer.\n- [EdgeDB](https://www.edgedb.com/) is an alternative to SQL focused on\n  traditional transactional workloads (as opposed to PRQL's focus on analytical\n  workloads). Their post\n  [We can do better than SQL](https://www.edgedb.com/blog/we-can-do-better-than-sql)\n  contains many of the criticisms of SQL that inspired PRQL.\n- [FunSQL.jl](https://github.com/MechanicalRabbit/FunSQL.jl) is a library in\n  Julia which compiles a nice query syntax to SQL. It requires a Julia runtime.\n- [LINQ](https://learn.microsoft.com/en-us/dotnet/csharp/linq/get-started/write-linq-queries),\n  is a pipelined language for the `.NET` ecosystem which can (mostly) compile to\n  SQL. It was one of the first languages to take this approach.\n- [Sift](https://github.com/RCHowell/Sift) is an experimental language which\n  heavily uses pipes and relational algebra.\n\n> If any of these descriptions can be improved, please feel free to PR changes.\n\n{{</ faq >}}\n\n{{< faq \"How is PRQL different from all the projects that SQL has defeated?\" >}}\n\nMany languages have attempted to replace SQL, and yet SQL has massively _grown_\nin usage and importance in the past decade. There are lots\n[of](https://twitter.com/seldo/status/1513599841355526145)\n[reasonable](https://benn.substack.com/p/has-sql-gone-too-far?s=r#footnote-anchor-2)\n[critiques](https://erikbern.com/2018/08/30/i-dont-want-to-learn-your-garbage-query-language.html)\non these attempts. So a reasonable question is \"Why are y'all building something\nthat many others have failed at?\". Some thoughts:\n\n- PRQL is open. It's not designed for a specific database. PRQL will always be\n  fully open-source. There will never be a commercial product. We'll never have\n  to balance profitability against compatibility, or try and expand up the stack\n  to justify a valuation. Whether someone is building a new tool or writing a\n  simple query — PRQL can be _more_ compatible across DBs than SQL.\n- PRQL is analytical. The biggest growth in SQL usage over the past decade has\n  been from querying large amounts of data, often from analytical DBs that are\n  specifically designed for this — with columnar storage and wide denormalized\n  tables. SQL carries a lot of unrelated baggage, and focusing on the analytical\n  use-case lets us make a better language.\n- PRQL is simple. There's often a tradeoff between power and accessibility\n  — e.g. rust is powerful vs. Excel is accessible — but there are also instances\n  where we can expand the frontier. PRQL's orthogonality is an example of\n  synthesizing this tradeoff — have a single `filter` rather than `WHERE` &\n  `HAVING` & `QUALIFY` brings both more power _and_ more accessibility.\n\nIn the same way that \"SQL was invented in the 1970s and therefore must be bad\"\nis questionable logic, \"`n` languages have tried and failed so therefore SQL\ncannot be improved.\" suffers a similar fallacy. SQL isn't bad because it's old.\nIt's bad because — in some cases — it's bad.\n\n{{</ faq >}}\n\n{{< faq \"Which databases does PRQL work with?\" >}}\n\nPRQL compiles to SQL, so it's compatible with any database that accepts SQL.\n\nA query's dialect can be explicitly specified, allowing for dialect-specific SQL\nto be generated. See the\n[Dialect docs](https://prql-lang.org/book/project/target.html) for more info;\nnote that there is currently very limited implementation of this, and most\ndialects' implementation are identical to a generic implementation.\n\n{{</ faq >}}\n\n{{< faq \"What's this `aggregate` function?\" >}}\n\n**...and why not just use `SELECT` & `GROUP BY`?**\n\nSQL uses `SELECT` for all of these:\n\n- Selecting or computing columns, without changing the shape of the data:\n\n  ```sql\n  SELECT x * 2 FROM y as two_x\n  ```\n\n- Reducing a column into a single row, with a reduction function:\n\n  ```sql\n  SELECT SUM(x) FROM y\n  ```\n\n- Reducing a column into groups, with a reduction function and a `GROUP BY`\n  function:\n\n  ```sql\n  SELECT SUM(x) FROM y GROUP BY z\n  ```\n\nThese are not orthogonal — `SELECT` does lots of different things depending on\nthe context. It's difficult for both people and machines to evaluate the shape\nof the output. It's easy to mix meanings and raise an error (e.g.\n`SELECT x, MIN(y) FROM z`).\n\nPRQL clearly delineates two operations with two transforms:\n\n- `select` — picking & calculating columns. These calculations always produce\n  exactly one output row for every input row.\n\n  ```prql\n  from employees\n  select name = f\"{first_name} {last_name}\"\n  ```\n\n- `aggregate` — reducing multiple rows to a single row, with a reduction\n  function like `sum` or `min`.\n\n  ```prql\n  from employees\n  aggregate [total_salary = sum salary]\n  ```\n\n`aggregate` can then be used in a `group` transform, where it has exactly the\nsame semantics on the group as it would on a whole table — another example of\nPRQL's orthogonality.\n\n```prql\nfrom employees\ngroup department (\n  aggregate [total_salary = sum salary]\n)\n```\n\nWhile you should be skeptical of new claims from new entrants\n[Hadley Wickham](https://twitter.com/hadleywickham), the developer of\n[Tidyverse](https://www.tidyverse.org/)\n[commented](https://news.ycombinator.com/item?id=30067406) in a discussion on\nPRQL:\n\n> FWIW the separate `group_by()` is one of my greatest design regrets with dplyr\n> — I wish I had made `by` a parameter of `summarise()`, `mutate()`, `filter()`\n> etc.\n\nFor more detail, check out the docs in the\n[PRQL Book](https://prql-lang.org/book/reference/stdlib/transforms/aggregate.html).\n\n{{</ faq >}}\n\n{{< faq \"Can PRQL write to databases?\" >}}\n\nPRQL is focused on analytical queries, so we don't currently support writing or\nmodifying data in databases. However, PRQL queries can be used to generate SQL\nstatements that write to databases. For example, surround the SQL output of a\nPRQL query in `CREATE OR REPLACE TABLE foo AS (...)`.\n\n{{</ faq >}}\n\n{{< faq \"Is it 'PRQL' or 'prql' or 'Prql'?\" >}}\n\nIt's `PRQL`, since it's a backronym! We name the repo and some libraries `prql`\nbecause of a strong convention around lowercase, but everywhere else we use\n`PRQL`.\n\n{{</ faq >}}\n\n{{< faq \"Where can I find the logos?\" >}}\n\nSee our [press materials](https://github.com/PRQL/prql-brand).\n\n{{</ faq >}}\n"

The repetition in the `WHERE` clause\n  obfuscates the meaning of the expression.\n- Functions have multiple operators — `HAVING` & `WHERE` are fundamentally\n  similar operations applied at different stages of the pipeline, but SQL's lack\n  of pipeline-based precedence requires it to have two different operators.\n- Operators have multiple functions — the `SELECT` operator both creates new\n  aggregations, and selects which columns to include.\n- Awkward syntax — when developing the query, commenting out the final line of\n  the `SELECT` list causes a syntax error because of how commas are handled, and\n  we need to repeat the columns in the `GROUP BY` clause in the `SELECT` list.\n\nHere's the same query with PRQL:\n\n```prql\nfrom employees                                # Each line transforms the previous result.\nfilter start_date > @2021-01-01               # Clear date syntax.\nderive {                                      # `derive` adds columns / variables.\n  gross_salary = salary + payroll_tax,\n  gross_cost = gross_salary + benefits_cost   # Variables can use other variables.\n}\nfilter gross_cost > 0\ngroup {title, country} (                      # `group` runs a pipeline over each group.\n  aggregate {                                 # `aggregate` reduces a column to a row.\n    average salary,\n    sum     salary,\n    average gross_salary,\n    sum     gross_salary,\n    average gross_cost,\n    sum_gross_cost = sum gross_cost,          # `=` sets a column name.\n    ct = count this,\n  }\n)\nsort {sum_gross_cost, -country}               # `-country` means descending order.\nfilter ct > 2_000\ntake 20\n```\n\nAs well as using variables to reduce unnecessary repetition, the query is also\nmore readable — it flows from top to bottom, each line representing a\ntransformation of the previous line's result. For example, `TOP 20` / `take 20`\nmodify the final result in both queries — but only PRQL represents it as the\nfinal transformation. And context is localized — the `aggregate` transform is\nimmediately wrapped in a `group` transform containing the columns to group by.\n\nWhile PRQL is designed for reading & writing by people, it's also much simpler\nfor code to construct or edit PRQL queries. In SQL, adding a filter to a query\ninvolves parsing the query to find and then modify the `WHERE` statement, or\nwrapping the existing query in a CTE. In PRQL, adding a filter just involves\nappending a `filter` transformation to the query.\n\nFor more examples, check out the [PRQL Book](https://prql-lang.org/book/).\n\n<!--\n\nTODO: This was a nice example for the proposal, but until we get functions which can contain column names,\nit doesn't compile, and so is confusing. When we get that working, we can re-enable it.\n\n## A more complex example\n\nHere's another SQL query, which calculates returns from prices on days with\nvalid prices.\n\n> The implemented version of PRQL supports some but not all these features.\n\n```sql\nWITH total_returns AS (\n  SELECT\n    date,\n    sec_id,\n    -- Can't use a `WHERE` clause, as it would affect the row that the `LAG` function referenced.\n    IF(is_valid_price, price_adjusted / LAG(price_adjusted, 1) OVER\n      (PARTITION BY sec_id ORDER BY date) - 1 + dividend_return, NULL) AS return_total,\n    IF(is_valid_price, price_adjusted_usd / LAG(price_adjusted_usd, 1) OVER\n      (PARTITION BY sec_id ORDER BY date) - 1 + dividend_return, NULL) AS return_usd,\n    IF(is_valid_price, price_adjusted / LAG(price_adjusted, 1) OVER\n      (PARTITION BY sec_id ORDER BY date) - 1 + dividend_return, NULL)\n      - interest_rate / 252 AS return_excess,\n    IF(is_valid_price, price_adjusted_usd / LAG(price_adjusted_usd, 1) OVER\n      (PARTITION BY sec_id ORDER BY date) - 1 + dividend_return, NULL)\n      - interest_rate / 252 AS return_usd_excess\n  FROM prices\n)\nSELECT\n  *,\n  return_total - (interest_rate / 252) AS return_excess,\n  EXP(SUM(LN(GREATEST(1 + return_total - (interest_rate / 252), 0.01))) OVER (ORDER BY date)) AS return_excess_index\nFROM total_returns\nJOIN interest_rates USING (date)\n```\n\n> This might seem like a convoluted example, but it's taken from a real query.\n> Indeed, it's also simpler and smaller than the full logic — note that it\n> starts from `price_adjusted`, whose logic had to be split into a previous\n> query to avoid the SQL becoming even less readable.\n\nHere's the same query with PRQL:\n\n```prql\nprql version:0.3 db:snowflake                         # PRQL version & database name.\n\nfunc excess x -> (x - interest_rate) / 252            # Functions are clean and simple.\nfunc if_valid x -> is_valid_price ? x : null\nfunc lag_day x -> group sec_id (                      # `group` is used for window partitions too\n  sort date\n  window (                                            # `window` runs a pipeline over each window\n    lag 1 x                                           # `lag 1 x` lags the `x` col by 1\n  )\n)\n\nfunc ret x -> x / (x | lag_day) - 1 + dividend_return\n\nfrom prices\njoin interest_rates (==date)\nselect [                                              # `select` only includes unnamed columns, unlike `derive`\n  return_total =      prices_adj   | ret | if_valid   # `|` can be used rather than newlines\n  return_usd =        prices_usd   | ret | if_valid\n  return_excess =     return_total | excess\n  return_usd_excess = return_usd   | excess\n  return_index = (                                    # No need for a CTE\n    return_total + 1\n    excess\n    greatest 0.01\n    ln\n    group sec_id (                                    # Complicated logic remains clear(er)\n      sort date\n      window ..current (                              # Rolling sum\n        sum\n      )\n    )\n    exp\n  )\n]\n```\n\nBecause we define the functions once rather than copying & pasting the code, we\nget all the benefits of encapsulation and extensibility — we have reliable &\ntested functions, whose purpose is explicit, which we can share across queries\nand between colleagues.\n\nWe needed a CTE in the SQL query, because the lack of variables would have\nrequired a nested window clause, which isn't allowed. With PRQL, our logic isn't\nconstrained by these arbitrary constraints — and is more compressed as a result.\n\nThe larger query demonstrates PRQL orthogonality. PRQL has fewer keywords\nthan SQL, and each of them does something specific and composable; for example:\n\n- `group` maps a pipeline over groups; whether in a table context — `GROUP BY`\n  in SQL — or within a `window` — `PARTITION BY` in SQL.\n- A transform in context of a `group` does the same transformation to the group\n  as it would to the table — for example finding the rolling sum of a column.\n  For more on this equivalence, check out [`group`'s\n  documentation](https://prql-lang.org/book/reference/transforms/group.html)\n- `filter` filters out rows which don't meet a condition. That can be before an\n  aggregate — `WHERE` in SQL — after an aggregate — `HAVING` in SQL — or within\n  a `window` — `QUALIFY` in SQL. -->\n"

    "content": "---\ntitle: A functional approach to relational queries\ndate: 2023-01-07\nauthors: [\"Aljaž Mur Eržen\"]\nlayout: article\ntoc: true\nurl: functional-relations\n---\n\nI believe that many of the ideas from functional programming are very suitable\nfor a query language. To make a case for it, I'll briefly explain a few\nfeatures, adapt their syntax, and show how they are used in PRQL.\n\n## Fancy functional features\n\nFunctional programming is an old-school programming paradigm that is gradually\ngaining traction within a few common languages that are designed with procedural\nparadigm in mind.\n\nThe many aspects of the paradigm have been discussed extensively, so I'll try to\nbe brief. If you've already read them all, I suggest you skip to the next\nsection.\n\n### Pure functions\n\nThis is the core aspect that allows us to do most of the magic later. When we\nsay \"pure function\", we just mean the mathematical function and not \"a\nprocedure\" or \"a method\". To be more precise:\n\n- Pure functions have no side effects. This means that no global state is\n  altered. The function result is the only output that the function produces.\n- Pure functions produce the same output given the same args. The output does\n  not depend on any external information; for example the current time or a\n  random number generator.\n\nThe most obvious effect is that for a pure function `my_function`, this:\n\n```js\nres1 = my_function(arg);\nres2 = my_function(arg);\nres3 = my_function(arg);\n```\n\n... is equivalent to:\n\n```js\nres1 = my_function(arg);\nres2 = res1;\nres3 = res2;\n```\n\nBecause `my_function` is guaranteed to return the same result when given `arg`,\nwe can skip calling `my_function` for the second and the third time because we\nalready know what the output will be.\n\nThis may seem like a minor point, but we're just getting started.\n\n### First-class citizens\n\nFunctions being \"first-class citizens\" means that they are treated the same as\nany other value; they can be stored in a variable, they can be passed to another\nfunction as an argument or even be used in binary operations.\n\n```js\nfunction double(x) {\n  return 2 * x;\n}\n\nlet preprocess = double;\n\nmy_array = [4, 5, 6];\n\nmy_array.map(preprocess);\n// yields [8, 10, 12]\n```\n\nHere, we've stored function `double` in variable `preprocess` and then passed\nthat to method `Array.map`, which applies a given function to each of the array\nelements.\n\n### Currying\n\nNamed after Haskell Curry, currying is an implicit act of converting a function\ncall with missing arguments into a new function.\n\n```js\nfunction add(x, y) {\n  return x + y;\n}\nlet add_one = add(1);\n```\n\nBecause we didn't specify `y` parameter of `add` function, the result is a new\nfunction that is still waiting for the last argument. It is equivalent to\ndefining add_one like this:\n\n```js\nfunction add_one(y) {\n  return add(1, y);\n}\n```\n\n### Implicit function call\n\nLet's suppose that we have a pure function that doesn't take any arguments:\n\n```js\nfunction my_function() {\n  return 42;\n}\n```\n\nBecause it is a pure function, it cannot depend on anything other than its\nnon-existing arguments. Another way to phrase it, this is a constant expression.\n\nAnd as such, it might as well be defined as one:\n\n```js\nlet my_var = 42;\n```\n\nIn conventional programming languages[^1], there is a difference between using\n`my_function()` and `my_var`. The first one evaluates the expression at the call\nsite, while the second one evaluates it at the declaration site. It is also\npossible to express just `my_function`, a reference to a function that can be\ncalled without arguments.\n\nBut if all functions are pure, we generalize by saying that all three cases are\nequivalent.\n\nTo make this work, let's say that `my_function` is \"implicitly invoked\" just as\nit would have been expressed as `my_function()`.\n\nAlso, if we declare all functions to be pure it doesn't matter exactly _when_\nthey are evaluated. So let's give the compiler the authority to make an informed\nguess about _when_ and make `my_var` and `my_function()` semantically\nequivalent.\n\n[^1]:\n    Let's say that conventional languages are the first 15 from this list:\n    <https://survey.stackoverflow.co/2022/#most-popular-technologies-language-prof>\n\n## Syntax, surly shinier\n\nFirst of all, let's change the function call to this:\n\n```prql\n(my_function arg1 arg2 arg3)\n```\n\nIt may look strange because the function name is within the parenthesis and\nthere are no commas between arguments. But there are benefits to this syntax.\n\nFirstly, when the call has no arguments, the parenthesis can be omitted:\n\n```prql\n(my_function) == my_function\n```\n\nwhich feels very natural because of the similar behavior with expressions. As\nintended, a function call with no argument and a plain reference to the function\nare expressed with the same syntax.\n\nLet's extend this behavior and allow bare function calls in a few places where\nthey won't become ambiguous:\n\n```prql\n# a list:\n[my_function arg1 arg2 arg3, my_function arg4 arg5 arg6]\n# a declaration:\nlet res = my_function arg1 arg2 arg3\n```\n\nSecondly, I'd argue that currying looks natural.\n\n```prql\nlet curry = my_function arg1 arg2\nlet res = curry arg3\n\n# or inline:\nlet res = (my_function arg1 arg2) arg3\n```\n\nNow let's go one step further and introduce a \"pipe\" operator. It applies its\nleft operand as an argument to the right operand:\n\n```prql\narg3 | my_function arg1 arg2\n```\n\nThis is especially useful for chaining function calls. If we declare `div`,\n`floor` and `mul` as common arithmetic functions, the function call syntax\nstarts to make sense:\n\n```prql\n12 | div 5 | floor | mul 5\n```\n\n## Running real relations\n\nUp to this point, we've discussed language design in the abstract, without\nknowing what it will be used for. Designing for the sake of \"language being\ncool\" is fine, but we do have a use for it, which means that the language must\nbe designed to be the right tool for the job.\n\nThe job, in the case of PRQL, is querying databases.\n\nThe core unit of data here is a \"relation\": an ordered set of rows, each of\nwhich contains entries for each of the columns. (More people are likely to be\nfamiliar with a \"table\", which is a relation stored in a DB.)\n\nQueries operate in a static environment that contains references to database\ntables and a library of standard functions. The important keyword here is\n\"static\" by which I mean \"global immutable variables\" that can be referenced\nfrom pure functions [^2].\n\nPRQL currently supports most of the features described in previous sections,\nfocused on the innovative function call syntax.\n\n[^2]:\n    Many functions in SQL are not pure, and we don't have a plan on\n    [how to deal with that](https://github.com/PRQL/prql/issues/1111).\n\n### Basics\n\nA basic operation on a relation would be:\n\n```prql\n(take 3 albums)\n# or with a pipeline:\n(albums | take 3)\n```\n\n... where `take` is a function and `albums` is a static relation. This does\nexactly what it sounds like: it limits the result to the first n rows. One could\nsay it selects the top n rows.\n\nIn actual PRQL queries, we have some rules regarding references to tables, which\nI'll talk about it some other time. For now, let's just say that for referencing\ntables (i.e. static relations) use the function `from`. It has the bonus that it\nmakes queries look a lot more like SQL:\n\n```prql\n(from albums | take 3)\n```\n\nTo make querying easier, we have some neat name resolution rules that allow\nfunction arguments to refer to each other. In practice, it allows referring to\ncolumns of a relation in function calls:\n\n```prql\n(select [title, artist_id] default_db.albums)\n# and with a pipeline:\n(from albums | select {title, artist_id})\n```\n\nAll these queries can be simplified to an expression of relations and scalars.\nIn PRQL, we call such expressions \"Relational Queries\" or RQ for short. It is an\nintermediate representation of prqlc and can be translated to SQL and executed\non basically any relational database.\n\nThis is the gist of how to express SQL queries with a functional language. At\nthis stage a curious reader might ask \"can PRQL express any SQL query?\" to which\nI'd say: almost. Another might be wondering \"but is it less cumbersome and more\nconsistent?\" and I'd reply \"very much, yes\", but it depends on whom you ask. And\nsomeone might say \"why functional?\" to which I say \"exactly the question I was\nwaiting for!\".\n\nThere are a few quick benefits I want to get out of the way:\n\n- Pipelines make the flow of the query \"top-to-bottom\". An earlier part of a the\n  pipeline will always be a valid query, regardless of what follows.\n- Functions on relations (transforms) are designed to be orthogonal. Each of\n  them has as few effects as possible and can be used at any point in the\n  pipeline (except for `from`).\n\nBut there is more.\n\n### Aggregate\n\nAt this point, I have to introduce `aggregate`. It takes a relation and produces\na single row using some aggregation function:\n\n```prql\n(from albums | aggregate {n_albums = count})\n```\n\nWhat happens if we don't specify the leading relation?\n\n```prql\n(aggregate {n_albums = count})\n```\n\nBecause `aggregate` is missing an argument, currying kicks in, and the whole\nexpression evaluates to a function that is still waiting for a relation.\n\nIn SQL it is common to use GROUP BY when aggregating. If you think about it, it\nessentially separates the relation into groups using some criteria and then\napplies `aggregate` to each of the groups. This is exactly how PRQL expressed\nit:\n\n```prql\nfrom albums | group artist_id (aggregate {n_albums = count})\n```\n\nThis is a lot for one line, so let's unveil new syntactic conveniences: a new\nline is a pipe operator and the top-level pipeline does not need parenthesis.\nI'll also add a new transform at the back, don't worry about it.\n\n```prql\nfrom albums\ngroup artist_id (\n    aggregate {n_albums = count}\n)\nfilter n_albums > 3\n```\n\nNotice how `group` operates on the whole relation it gets from `from` and that\n`aggregate` is passed to `group` as a function to be applied to each of the\ngroups. `aggregate` then converts each of the groups into a single row and\nreturns that to `group` that composes these rows back together. This can now be\npassed on to `filter`, which will remove any rows that don't match its\ncondition.\n\nIn SQL, a similar expression would have these four parts:\n\n- projection in SELECT,\n- an aggregation function that implicitly triggers aggregation,\n- GROUP BY clause,\n- HAVING clause.\n\nThese parts are entangled syntactically and semantically into one feature we\nunderstand as GROUPING.\n\nThe beautiful realization is that these are 3 different operations that are\nhappening and that when separated they don't need to be associated with each\nother. For example `filter` is more commonly expressed as WHERE and `group` has\nother uses than `aggregate`.\n\nBut to separate these core relational operations, we need a way to express\naggregate as a function. This is why the functional paradigm fits the relational\ndata model.\n\n### Distinct\n\nA common question when learning SQL is \"how do I select the row where column x\nis smallest?\". It has many variations, but there are two ways of doing it:\n\n```sql\n-- option 1\nSELECT x, y, z FROM tab ORDER BY x LIMIT 1\n\n-- option 2\nSELECT x, y, z FROM tab WHERE x = (SELECT min(x) FROM tab)\n```\n\n[A follow-up question](https://stackoverflow.com/questions/3800551/select-first-row-in-each-group-by-group)\nwould be \"how do I select the row where column x is smallest, for each group\nover y?\". This seems like a similar problem but the solution in SQL is\nsurprisingly different:\n\n```sql\n-- option 1 (unsupported in some dialects)\nSELECT DISTINCT ON (y) x, y, z FROM tab ORDER BY y, x, z;\n\n-- option 2  (supported by most dialects)\nWITH summary AS (\n    SELECT x, y, z,\n        ROW_NUMBER() OVER(PARTITION BY y ORDER BY x) AS rank\n    FROM tab)\nSELECT * FROM summary WHERE rank = 1\n```\n\nNow break the query down into core operations. Essentially we want to do the\nsame thing we did before, but performed in groups by `y`. Before we used SQL\nthat can be expressed as `sort x | take 1` (which evaluates to a function), so\nnow surely this should work:\n\n```prql\nfrom tab\ngroup y (sort x | take 1)\n```\n\nAnd it does. You can go and test this out in the\n[PRQL playground](https://prql-lang.org/playground/).\n\nAnother variation of the question would be \"how do I select a row, for each\ngroup over all columns?\". If you phrase it differently \"group by all columns and\nthen take one row from each group\". Or another way: \"select distinct values of\nall columns\".\n\n```prql\nfrom tab\ngroup tab.* (take 1)\n```\n\nAs you can see, our language has many shortcuts for expressing operations such\nas DISTINCT. This is convenient for us humans, but it's not a good base for a\nrelational query language.\n\nI hope my point is clear: relational query language benefits a lot by separating\noperations into orthogonal transforms[^3]. These transforms are in most cases\npure functions that are easiest to express in a functional language.\n\n<!-- SQL, on the other hand, uses many keywords and syntactic constructs to\nexpress the most commonly used combinations of these transforms. This falls short\nwhen trying to express uncommon operations while not providing significantly\nshorter queries. -->\n\nIf you want to see more of what PRQL is capable of, come and check out\n[the project](https://github.com/PRQL/prql). It may not have monads (yet), but\nit's probably better than what you are forced to use now.\n\n[^3]:\n    Transforms in PRQL are not completely orthogonal. `select`, `derive`,\n    `aggregate` and `join` all manipulate relation columns. So in a sense, they\n    are much closer to each other than they are to `take`.\n\n## Appendix\n\n### PRQL support\n\nPRQL is a work in progress. It does not yet support all the features presented\nhere, namely:\n\n- `let` syntax for variable declarations,\n- inline currying - function call must start with a function name,\n- syntax for declaring tables.\n\nWe focused on the core features and left these out because they can be worked\naround.\n\nAlso, PRQL may not ever get all of these features, because the ideas in this\narticle are only my own and not necessarily of the whole PRQL core team.\n\n### In math, function call syntax is ambiguous\n\nIf you think about it, the function call syntax from math is kind of ambiguous.\nFor example, what does this mean:\n\n```math\na(b + 1)\n```\n\nIt could either be a call of function a, or it could be just multiplication\nwhere we omitted `*`. This is not a problem in conventional programming\nlanguages because they don't allow omitting the `*`.\n"

At the time of\nwriting it supports duckdb and datafusion, but we can also connect to many other\nengines through these two.\n\nBut I don't need that today, plain duckdb will do:\n\n```\n$ pq --backend=duckdb \\\n     --from \"tt=~/time-tracking.csv\" \\\n     '{here comes the PRQL query below}'\n```\n\n```prql\n# function declaration that is a wrapper for substr SQL function\nlet substr = text start len -> s\"substr({text}, {start}, {len})\"\n\n\n# start of the pipeline\nfrom tt  # as declared in --from\n\n# compute a few new columns\nderive [\n    date = substr time 0 11,    # call the substr function to\n                                # extract date from column `time`\n    prev_action = lag 1 action, # lag column `action`\n    prev_time = lag 1 time,     # lag column `time`\n]\n\n# pick only rows that correspond to intervals that I want to track\nfilter action == \"stop\" and prev_action == \"start\"\n\n# for each date\ngroup date (\n    # sum durations of those intervals\n    aggregate [sec = sum s\"EXTRACT(EPOCH FROM {time - prev_time})\"]\n)\n\n# compute more columns\nderive [\n    hours = substr f\"00{sec / (60 * 60)}\" 0-2 2,\n    minutes = substr f\"00{(sec / 60) % 60}\" 0-2 2,\n    seconds = substr f\"00{sec % 60}\" 0-2 2,\n]\n\n# expose only date and pretty-printed duration\nselect [\n    date,\n    duration = f\"{hours}:{minutes}:{seconds}\"\n]\n```\n\nWhen run on the file above, prql-query produces this pretty table:\n\n```\n+------------+----------+\n| date       | duration |\n+------------+----------+\n| 2023-01-27 | 03:04:20 |\n+------------+----------+\n```\n\nThe full script implementation adds some conveniences like error handling and\nbetter output formatting, but the core concept remains: simple CSV logging that\ncan be queried with PRQL.\n"

    "content": "---\ntitle: Format pretty reports\ndate: 2023-01-28\nauthors: [\"richb-hanover\"]\nlayout: article\ntoc: false\n---\n\n> I can no longer bring myself to write bare SQL - PRQL makes building queries\n> so easy. So here's how I use PRQL _functions_ and _aliases_ for naming\n> variables to \"pretty up\" a SQL report.\n\nI have an SQLite database with a table named `PropertyData` and I want to show\nthe change of column `App_Total2020` and `App_Total2021` across years,\ndisplaying their values along with their percent change.\n\n## Functions\n\nOf course, property values are in dollars. So I could simply display them as\n`450000`. But they are more compelling if they're written as `$450,000`. Writing\nthe SQL code and format strings for each column would be tedious and\nerror-prone. PRQL allows me to create a `dollars` function and then use it\nmultiple times:\n\n```prql\n# dollars displays a numeric value as whole dollars with commas\nlet dollars = d -> s\"\"\"printf(\"$%,d\",{d})\"\"\"\n\nselect {\n    (dollars App_Total2020),\n    (dollars App_Total2021),\n}\n```\n\nI also want to compute the percent change between values. It's easy to create a\n`percent_diff` function:\n\n```prql\n# percent_diff computes the amount (percent) the new differs from old\nlet percent_diff = old new -> 100.0*( new - old ) / old\n```\n\nOne final function: the `percent_diff` function returns a floating point number\nwith many digits after the decimal place. I only want to display one place in my\nresults, with a trailing `%`. So I wrote a `format_percent` function that uses a\n`printf()` to format the value.\n\n```prql\n# format_percent prints a floating point number with \"%\"\nlet format_percent = v -> s'printf(\"%1.1f%\", {v})'\n```\n\n## Column Headings\n\nUse a PRQL _alias_ to assign each column a nice name. This becomes its column\nheading. The examples above might be:\n\n```prql\nselect {\n    Appraisal2020 = (dollars App_Total2020),\n   `Appraisal 2021` = (dollars App_Total2021),\n}\n```\n\nNote how the second example puts the column heading in backticks to preserve\nspaces.\n\n## Excluding certain columns\n\nI want to sort results by the (numeric) percent change, but I don't want to\ndisplay that percentage value (with multiple decimal places) in the final table.\nSo I split the query into pieces: the first `select` collects all the necessary\ncolumns, adding a new column using `percent_diff`. The query then sorts the\nvalues and passes those results to a second `select` that's responsible for\nformatting the column headings and contents (using aliases and\n`format_percent`).\n\n## Putting it all together\n\nHere is my workflow for a typical query using the tools listed below: [^1]\n\n- Enter the PRQL query in the VS Code editor. Use a `.prql` suffix for the file.\n- Open the PRQL VS Code extension (Ctl-Shift-P, or Cmd-Shift-P on Mac). It'll\n  appear and display the compiled SQL in a second pane on the right.\n- Copy the SQL from the right pane and paste it into the DBM program. Run the\n  query. That's it!\n\nHere's the PRQL for this example, followed by the result from my database.\n_Note:_ Paste the PRQL query below into the\n[Playground](https://prql-lang.org/playground/) to see what the PRQL compiler\nproduces.\n\n```prql\n# dollars displays a numeric value as dollars with commas\nlet dollars = d -> s\"\"\"printf('$%,d',{d})\"\"\"\n\n# percent_diff computes the amount (percent) the new differs from old\nlet percent_diff = old new -> 100.0*( new - old ) / old\n\n# format_percent prints a floating point number with \"%\"\nlet format_percent = v -> s\"printf('%1.1f%', {v})\"\n\n# Step 1: First calculate important columns\nfrom PropertyData\nselect {\n    Map, Lot,\n    App_Total2020,\n    App_Total2021,\n    pct_change = (percent_diff App_Total2020 App_Total2021),\n}\n\n# Step 2: Sort the resulting table by pct_change\nsort {-pct_change}\n\n# Step 3: Format the column headings and contents\nselect {\n    Map, Lot,\n    Appraisal2020 = (dollars App_Total2020),\n   `Appraisal 2021` = (dollars App_Total2021),\n   `Percent Change` = (format_percent pct_change),\n}\ntake 20\n```\n\nThe image below shows the result of that query:\n\n- the column headings match the _aliases_ of the second `select` statement,\n- the `dollars` function formats values with `$` and `,` as expected,\n- the `percent_diff` function computes the percent change between the _old_ and\n  _new_ values,\n- the `format_percent` function formats the value with a single decimal place\n  and appends a `%`.\n\n![First rows](./query_result.png)\n\n[^1]:\n    **My Tools:** I use [Visual Studio Code](https://code.visualstudio.com/) to\n    maintain a folder of PRQL queries for re-use. I use the\n    [PRQL VS Code extension](https://marketplace.visualstudio.com/items?itemName=PRQL-lang.prql-vscode)\n    to compile PRQL into SQL.

It immediately sparked the interest of many people dealing with\ndata. The project grew a community of people who are now developing the\nlanguage, tooling, and the idea of a modern relational language. Since then\nwe've opened 1577 issues & PRs on [our main repo](https://github.com/PRQL/prql),\nsubmitted 4211 comments, and made 1176 commits.\n\nThe number of stars is skyrocketing every time the project appears on Hacker\nNews, which we believe to be an indicator that people are eager to adopt the\nlanguage if the tooling is made accessible enough.\n\n![](FQ9QSOo.png)\n\n## Where are we?\n\nLanguage design & development in the last year have been focused on these areas:\n\n- design of basic\n  [transforms](https://prql-lang.org/book/reference/stdlib/transforms/) and\n  their [interactions](https://github.com/PRQL/prql/issues/300),\n\n- fundamentals of how [functions](https://github.com/PRQL/prql/issues/444) and\n  pipelines are [evaluated](#define-functional-semantics).\n\n- small quality-of-life language features (e.g. syntax for\n  [f-strings, dates, coalesce operator](https://prql-lang.org/book/reference/syntax/),\n  [case](https://github.com/PRQL/prql/issues/504)),\n\nPRQL is now in a state where it can greatly improve the developer experience for\nwriting complex analytical queries, but it does require a bit of fiddling to set\nup in your environment.\n\nIn the coming year, we are aiming to improve that by providing a dbt plugin and\nintegrations for tools like Rill-developer, Metabase, and DataGrip. Read more\nabout our plans and ambitions in [the roadmap](https://prql-lang.org/roadmap/).\n\n## How are people using it?\n\nFor data analytics at [SuperSimple](https://gosupersimple.com/):\n\n> We've been using PRQL under the hood to power complex analytics workflows at\n> Supersimple for more than 6 months now.

In the summary of the year, we\nwant to fix that and put a spotlight on the amazing work that was done.\n\n### Playground\n\nWe have a [Playground](https://prql-lang.org/playground/) that can compile and\nexecute PRQL queries in-browser. It's using prqlc and DuckDB, both compiled to\nWASM modules.\n\n![PRQL Playground](URpCf29.png)\n\nCurrently, this is the best way to see how the relation is manipulated instantly\nas you type the query.\n\n### VS Code extension\n\nExtension that provides syntax highlighting and compiled SQL within your editor.\n\n![VS Code extension](7cpDySb.png)\n\n### prql-query\n\nCLI tool that uses DuckDB and DataFusion to execute PRQL queries from your\nterminal. Useful for wrangling your CSV and parquet files on the go.\n\n![pq](ncVXken.png)\n\n### Define functional semantics\n\nGiven the initial proposal of the language, we constructed consistent semantics\nof how functions in PRQL work, what they can express and how can they be abused.\n\nTo keep this post brief, we'll expose a single snippet of what's possible and\ninvite you to read more in\n[a recent post](https://prql-lang.org/functional-relations/).\n\n```prql\nlet take_oldest = n rel -> (\n    rel\n    sort [-invoice_date]\n    take n\n)\n\nfrom invoices\ntake_oldest 3\n```\n\n> Function `take_oldest` is used in the main pipeline, just any other regular\n> transform.\n\n### Relational Query\n\nThe design of prqlc strives to have a complexity bottleneck with an intermediate\nrepresentation named\n[Relation Query](https://docs.rs/prqlc/latest/prqlc/ir/rq/index.html) or RQ for\nshort. Think of it as equivalent to a [Substrait plan](https://substrait.io/).\n\nIts goal is the ability to express any operation possible in SQL while\ncontaining as few constructs as possible. This makes it easy to implement\nbackends that compile RQ to SQL or any other language or library dealing with\nrelations or dataframes.\n\n![](GXLvoXn.png)\n\n> Note how prqlc inferred the structure of the table we are selecting from.

One of its goals is to simplify working with data wherever\nyou can currently use SQL. As such it compiles to SQL while making available\nmodern ergonomics such as\n[f-strings](https://prql-lang.org/book/reference/syntax/f-strings.html), as well\nas not so modern features such as\n[functions](https://prql-lang.org/book/reference/declarations/functions.html).\n\nGiven that the underlying semantics of Recursive CTEs are really about iteration\nor \"looping\", we have called this feature `loop` in PRQL.\n\n## Introducing `loop`\n\nRecursive CTEs in SQL consist of two parts, an `initial_query` and an\n`update_query`. First the `initial_query` is executed and then the rows produced\nare fed to `update_query` which is applied to the result set. The `update_query`\nis then iteratively applied to the rows produced in the last iteration until no\nmore rows are produced, at which point iteration stops. (For a great review of\nthis as well as some interesting proposals to extend the semantics of Recursive\nCTEs in SQL, see the paper\n[\"A Fix for the Fixation on Fixpoints\" by Denis Hirn and Torsten Grust](https://www.cidrdb.org/cidr2023/papers/p14-hirn.pdf).)\n\nThis behavior can be expressed with following pseudo-code:\n\n```python\ndef loop(step, initial_query):\n    result = []\n    current = initial_query()\n    while current is not empty:\n        result = append(result, current)\n        current = update_query(current)\n\n    return result\n```\n\nThe minimal `loop` example from the documentation in the\n[PRQL book](https://prql-lang.org/book/reference/stdlib/transforms/loop.html)\nis:\n\n```prql\nfrom_text format:json '[{\"n\": 1 }]'\nloop (\n    select n = n+1\n    filter n<=3\n)\n```\n\nHere we use a PRQL utility function `from_text` to conveniently turn a JSON\nrepresentation of some example data into a SQL table (`from_text` currently also\naccepts CSV input).\n\nInitially a row with `{\"n\":1}` is fed in. Then the update query is applied to\nthis which in this case just increments `n` by one and filters the result set to\nonly the rows where `n` is less than or equal to three. This produces `{\"n\":2}`\nin the next step and `{\"n\":3}` after that. On the next iteration `{\"n\":4}` is\nproduced but that is eliminated by the filter condition. Since that leaves no\nnew rows, iteration stops.\n\nIf you try the query above in the\n[PRQL Playground](https://prql-lang.org/playground), the result set you get (in\nthe \"output.arrow\" tab) is:\n\n| n   |\n| --- |\n| 1   |\n| 2   |\n| 3   |\n\n## Fibonacci Numbers\n\nInspired by this, let's try to calculate Fibonacci numbers which are often one\nof the first examples when recursion is introduced:\n\n```elm=\nfrom_text format:json '[{\"a\":1, \"b\":1}]'\nloop (\n    derive b_new = a + b\n    select [a=b, b=b_new]\n)\ntake 7\n```\n\nwhich produces the first 7 Fibonacci numbers.\n\n| a   |\n| --- |\n| 1   |\n| 1   |\n| 2   |\n| 3   |\n| 5   |\n| 8   |\n| 13  |\n\nYou might have noticed that we didn't actually include a `filter` in our loop\nthis time. Instead we relied on the fact that DuckDB produces results lazily and\nsince we only took 7 numbers it only produced what we needed.\n\nNow, let's set ourselves a bigger challenge.\n\n## Calculating the digits of pi\n\nMarch 14th is written on American calendars as 3/14 which reminds us of the\nfirst three digits of Pi=3.1415926535... . Therefore this day is commonly known\nas Pi day. In order to celebrate Pi Day 2023 and the recent release of `loop` in\nPRQL 0.6, why don't we try to calculate the digits of Pi in PRQL!\n\nFor our query engine we will use [DuckDB](https://duckdb.org/) because it is\nreally fast and has many modern features that make it ideally suited for the\nkinds of analytical queries that PRQL is targeting. There is even a\n[duckdb-prql](https://github.com/ywelsch/duckdb-prql) extension which allows you\nto write PRQL queries right inside DuckDB!\n\nWe follow the algorithms in the paper\n[\"Unbounded Spigot Algorithms for the Digits of Pi\" by Jeremy Gibbons](https://www.cs.ox.ac.uk/people/jeremy.gibbons/publications/spigot.pdf),\nin particular Rabinowitz and Wagon's Spigot Algorithm. While it is not the most\nefficient algorithm presented in the paper, it has the advantage that it uses\nonly standard data types while the more efficient algorithms rely on unbounded\ninteger types which are not available in many database systems.\n\nFor my implementation, I adapted the Python implementation by John Burkardt\nfound\n[here](https://people.sc.fsu.edu/~jburkardt/py_src/pi_spigot/pi_spigot.py). A\nbit of care had to be taken in porting the implementation to PRQL, as PRQL like\nSQL, is stateless so I introduced another state variable `k` to track the\nposition inside the body of the loop. In order to ensure that all values of `k`\nare handled in the query we define a PRQL function called `loop_steps`. The\nability to define functions in PRQL is one of its key features and I feel the\nquery below really shows the power that the composability of functions brings to\nPRQL. PRQL is a functional language with features such as currying. For more\ndetails see our previous post\n[A functional approach to relational queries](https://prql-lang.org/functional-relations/).\n\nThe resulting PRQL query is the following:\n\n```prql\nprql target:sql.duckdb\n\nlet config = (\n    from_text format:json '[{\"num_digits\":50}]'\n    derive {\n        array_len = (10*num_digits)/3,\n        calc_len = 1+4,\n        loop_len = array_len + calc_len,\n    }\n)\n\nlet loop_steps = step_0 step_i step_1 step_2 step_3 other -> case [\n    k==0 => step_0,\n    1 <= k and k <= array_len => step_i,\n    k==array_len+1 => step_1,\n    k==array_len+2 => step_2,\n    k==array_len+3 => step_3,\n    true => other,\n]\n\nlet q_steps = step_q9 step_q10 step_j2 step_jg2 other -> case [\n    q==9 => step_q9,\n    q==10 => step_q10,\n    j==2 => step_j2,\n    j>2 => step_jg2,\n    true => other,\n]\n\n\nfrom config\nselect [\n    num_digits,\n    array_len,\n    loop_len,\n    j = 0,\n    k = 0,\n    q = 0,\n    a = s\"[2 for i in range({array_len})]\",\n    nines = 0,\n    predigit = 0,\n    output = '',\n]\nloop (\n    filter j < num_digits + 1\n    derive [\n      j_new = case [k==0 => j+1, true => j],\n      k_new = (k+1) % loop_len,\n      q_step_i = (10*s\"{a}[{k}]\"+q*(array_len-k+1))/(2*(array_len-k)+1),\n      q_new = loop_steps 0 q_step_i (q/10) q q q,\n\n      a_step_i = s\"[CASE WHEN i=={k} THEN (10*{a}[i]+{q}*({array_len}-i+1))%(2*({array_len}-i)+1) ELSE {a}[i] END for i in generate_series(1,{array_len})]\",\n      a_step_1 = s\"[CASE WHEN i=={array_len} THEN {q}%10 ELSE {a}[i] END for i in generate_series(1,{array_len})]\",\n      a_new = loop_steps a a_step_i a_step_1 a a a,\n\n      nines_new = loop_steps nines nines nines (q_steps (nines+1) 0 nines nines nines) (case [q!=9 and q!=10 and nines!=0 => 0, true => nines]) nines,\n      predigit_new = loop_steps predigit predigit predigit (q_steps predigit 0 q q q) predigit predigit,\n\n      output_step_2 = (q_steps '' s\"({predigit}+1)::string || repeat('0', {nines})\" s\"{predigit}::string || '.'\" s\"{predigit}::string\" ''),\n      output_step_3 = (case [q!=9 and q!=10 and nines!=0 => s\"repeat('9', {nines})\", true => '']),\n      output_new = loop_steps '' '' '' output_step_2 output_step_3 '',\n    ]\n    select {\n        num_digits,\n        array_len,\n        loop_len,\n        j = j_new,\n        k = k_new,\n        q = q_new,\n        a = a_new,\n        nines = nines_new,\n        predigit = predigit_new,\n        output = output_new,\n    }\n)\naggregate [pi=s\"string_agg({output}, '')\"]\n```\n\nGo ahead and run this query right now in your browser with our\n[Online PRQL Playground](https://www.prql-lang.org/playground)! There you can\nalso see the SQL that is produced in the `output.sql` tab (for you convenience\nreproduced in the Appendix below) as well as the result of the calculation in\nthe `output.arrow` tab.\n\nThe output you see will be something like the following:\n\n```\n┌────────────────────────────────────────────────────┐\n│                         pi                         │\n│                      varchar                       │\n├────────────────────────────────────────────────────┤\n│ 3.141592653589793238462643383279502884197169399375 │\n└────────────────────────────────────────────────────┘\n```\n\nWhy don't you play around with the `num_digits` parameter to try and see how\nmany digits you can get on your laptop? (Unfortunately this algorithm is quite a\nbit more inefficient than the equivalent Python implementation as Recursive CTEs\ncurrently don't allow for state to be kept outside of the result set.)\n\nSomething you might have noticed is that there are some expressions surrounded\nby `s\"\"`. This is called an\n[s-string](https://prql-lang.org/book/reference/syntax/s-strings.html) (s for\nSQL) and allows us to include raw SQL inside our PRQL queries. We use this to\ninclude features from DuckDB that haven't made it into PRQL yet, such as the\nPythonesque\n[list comprehensions](https://duckdb.org/docs/sql/functions/nested.html#list-comprehension).\n\nThe `loop` functionality in PRQL is brand new and is marked as _experimental_\nand we will be working to stabilise the feature and iterate on the design to\nmake it as easy and useful as possible. We felt that it was exciting enough to\nshare it at this stage (and in time for Pi Day) and make it available for you to\ntry out and play around with. PRQL is developed completely in the open so let us\nknow your use cases so that we can make PRQL the best tool for the data\nchallenges that you face.\n\n## Conclusion\n\nRecursive CTEs in SQL make SQL Turing Complete and the same should hold for PRQL\nnow that `loop` is included. As we saw above, not all algorithms are easily\nexpressed in this paradigm, so while theoretically they could be, whether they\nshould be is another question. However I hope this example demonstrates that\n`loop` brings great power to PRQL and in follow up posts I will demonstrate how\nwe can use this to do tree and graph traversals which do come up in practice in\nthe kind of analytical data work that PRQL is made for. After that I will also\nlook at online algorithms such as moving averages an online gradient descent, so\nbe sure to come back for those!\n\n## Appendix\n\nThe following is the SQL query that was produced and run in DuckDB:\n\n```sql\nWITH table_0 AS (\n  SELECT\n    50 AS num_digits\n),\nconfig AS (\n  SELECT\n    num_digits,\n    10 * num_digits / 3 AS array_len,\n    5 AS calc_len,\n    10 * num_digits / 3 + 5 AS loop_len\n  FROM\n    table_0 AS table_1\n),\ntable_6 AS (\n  WITH RECURSIVE loop AS (\n    SELECT\n      num_digits,\n      array_len,\n      loop_len,\n      0 AS _expr_0,\n      0 AS _expr_1,\n      0 AS _expr_2,\n      [2 for i in range(array_len)] AS _expr_3,\n      0 AS _expr_4,\n      0 AS _expr_5,\n      '' AS _expr_6\n    FROM\n      config\n    UNION\n    ALL\n    SELECT\n      num_digits,\n      array_len,\n      loop_len,\n      _expr_12 AS _expr_15,\n      _expr_11 AS _expr_16,\n      _expr_10 AS _expr_17,\n      _expr_9 AS _expr_18,\n      _expr_8 AS _expr_19,\n      _expr_7 AS _expr_20,\n      CASE\n        WHEN _expr_1 = 0 THEN ''\n        WHEN 1 <= _expr_1\n        AND _expr_1 <= array_len THEN ''\n        WHEN _expr_1 = array_len + 1 THEN ''\n        WHEN _expr_1 = array_len + 2 THEN _expr_13\n        WHEN _expr_1 = array_len + 3 THEN _expr_14\n        ELSE ''\n      END\n    FROM\n      (\n        SELECT\n          num_digits,\n          array_len,\n          loop_len,\n          CASE\n            WHEN _expr_1 = 0 THEN _expr_5\n            WHEN 1 <= _expr_1\n            AND _expr_1 <= array_len THEN _expr_5\n            WHEN _expr_1 = array_len + 1 THEN _expr_5\n            WHEN _expr_1 = array_len + 2 THEN CASE\n              WHEN _expr_2 = 9 THEN _expr_5\n              WHEN _expr_2 = 10 THEN 0\n              WHEN _expr_0 = 2 THEN _expr_2\n              WHEN _expr_0 > 2 THEN _expr_2\n              ELSE _expr_2\n            END\n            WHEN _expr_1 = array_len + 3 THEN _expr_5\n            ELSE _expr_5\n          END AS _expr_7,\n          CASE\n            WHEN _expr_1 = 0 THEN _expr_4\n            WHEN 1 <= _expr_1\n            AND _expr_1 <= array_len THEN _expr_4\n            WHEN _expr_1 = array_len + 1 THEN _expr_4\n            WHEN _expr_1 = array_len + 2 THEN CASE\n              WHEN _expr_2 = 9 THEN _expr_4 + 1\n              WHEN _expr_2 = 10 THEN 0\n              WHEN _expr_0 = 2 THEN _expr_4\n              WHEN _expr_0 > 2 THEN _expr_4\n              ELSE _expr_4\n            END\n            WHEN _expr_1 = array_len + 3 THEN CASE\n              WHEN _expr_2 <> 9\n              AND _expr_2 <> 10\n              AND _expr_4 <> 0 THEN 0\n              ELSE _expr_4\n            END\n            ELSE _expr_4\n          END AS _expr_8,\n          CASE\n            WHEN _expr_1 = 0 THEN _expr_3\n            WHEN 1 <= _expr_1\n            AND _expr_1 <= array_len THEN [CASE WHEN i==_expr_1 THEN (10*_expr_3[i] + _expr_2 *(array_len - i + 1)\n          ) %(2 *(array_len - i) + 1)\n          ELSE _expr_3 [i]\n      END for i in generate_series(1, array_len) ]\n      WHEN _expr_1 = array_len + 1 THEN [CASE WHEN i==array_len THEN _expr_2%10 ELSE _expr_3[i]\n  END for i in generate_series(1, array_len) ]\n  WHEN _expr_1 = array_len + 2 THEN _expr_3\n  WHEN _expr_1 = array_len + 3 THEN _expr_3\n  ELSE _expr_3\nEND AS _expr_9,\nCASE\n  WHEN _expr_1 = 0 THEN 0\n  WHEN 1 <= _expr_1\n  AND _expr_1 <= array_len THEN (\n    10 * _expr_3 [_expr_1] + _expr_2 * (array_len - _expr_1 + 1)\n  ) / (2 * (array_len - _expr_1) + 1)\n  WHEN _expr_1 = array_len + 1 THEN _expr_2 / 10\n  WHEN _expr_1 = array_len + 2 THEN _expr_2\n  WHEN _expr_1 = array_len + 3 THEN _expr_2\n  ELSE _expr_2\nEND AS _expr_10,\n(_expr_1 + 1) % loop_len AS _expr_11,\nCASE\n  WHEN _expr_1 = 0 THEN _expr_0 + 1\n  ELSE _expr_0\nEND AS _expr_12,\n_expr_1,\nCASE\n  WHEN _expr_2 = 9 THEN ''\n  WHEN _expr_2 = 10 THEN (_expr_5 + 1) :: string || repeat('0', _expr_4)\n  WHEN _expr_0 = 2 THEN _expr_5 :: string || '.'\n  WHEN _expr_0 > 2 THEN _expr_5 :: string\n  ELSE ''\nEND AS _expr_13,\nCASE\n  WHEN _expr_2 <> 9\n  AND _expr_2 <> 10\n  AND _expr_4 <> 0 THEN repeat('9', _expr_4)\n  ELSE ''\nEND AS _expr_14,\n_expr_2,\n_expr_4\nFROM\n  loop AS table_2\nWHERE\n  _expr_0 < num_digits + 1\n) AS table_3\n)\nSELECT\n  *\nFROM\n  loop\n)\nSELECT\n  string_agg(_expr_6, '') AS pi\nFROM\n  table_6 AS table_5\n\n-- Generated by PRQL compiler version:0.6.1 (https://prql-lang.org)\n```\n"

    "content": "---\ntitle: \"Roadmap\"\nurl: roadmap\n---\n\n> We're excited and inspired by the level of enthusiasm behind the project, both\n> from individual contributors and the broader community of users who are\n> unsatisfied with SQL. We currently have an working version for the intrepid\n> users.\n>\n> We're hoping we can build a beautiful language, integrations that are\n> approachable & powerful, and a vibrant community. Many projects have reached\n> the current stage and fallen, so this requires compounding on what we've done\n> so far.\n>\n> -- {{< cite >}}PRQL Developers{{< /cite >}}\n\n## Medium term\n\n{{< columns >}}\n\n#### Integrations\n\nPRQL is focused at the language layer, which means we can easily integrate with\nexisting tools & apps. Integrations will be the primary way that people can\nstart using PRQL day-to-day. At first, the most impactful initial integrations\nwill be tools that engineers use to build data pipelines, like\n[`dbt-prql`](https://github.com/PRQL/prql/issues/375).\n\n#### Standard library\n\nCurrently, the standard library is\n[quite limited](https://github.com/PRQL/prql/blob/main/prqlc/prqlc/src/semantic/std.prql).\nIt contains only basic arithmetic functions (`AVERAGE`, `SUM`) and lacks\nfunctions for string manipulation, date handling and many math functions. We're\nlooking to gradually introduce these as needed, and reduce the need for\ns-strings.\n\nOne challenge here is the variety of functionalities and syntax of target DBMSs;\ne.g. there's no standard regex function.\n\n#### Type system\n\nBecause PRQL is meant to be the querying interface of the database, a type\nsystem that can describe database schema as well as all intermediate results of\nthe queries is needed. We want it to provide clear distinctions between\ndifferent nullable and non-nullable values, and different kinds of containers\n(e.g. scalars vs. columns).\n\nCurrently PRQL compiles into SQL with no understanding of the underlying tables.\nWe plan to introduce database schema declarations into the language, so PRQL\ncompiler and tooling can enrich the developer experience with autocomplete and\nearly error messages.\n\nThe goal here is to catch all errors at PRQL compile time, instead of at the\ndatabase's PREPARE stage.\n\n<--->\n\n#### Friendliness\n\nCurrently the compiler output's friendliness is variable — sometimes it produces\nmuch better error messages than SQL, but sometimes they can be confusing.\n\nBoth bug reports of unfriendliness, and code contributions to improve them are\nwelcome; there's a\n[friendliness label.](https://github.com/PRQL/prql/issues?q=is%3Aissue+label%3Afriendliness+is%3Aopen)\n\n#### Developer ergonomics — LSP\n\nThe PRQL language can offer a vastly improved developer experience over SQL,\nboth when exploring data and building robust data pipelines. We'd like to offer\nautocomplete both for PRQL itself and for columns of the underlying database,\nbecause fast iteration cycle can drastically decrease frustrations caused by\nbanal misspellings.\n\nThis requires development across multiple dimensions — writing an\n[LSP server](https://langserver.org/), better support for typing in the\ncompiler, and possibly database cohesion.\n\nWhile PRQL compiler will never depend on a database to compile queries, an LSP\nserver could greatly help with generating type definitions from the information\nschema of a database.\n\n#### Query transparency\n\nPRQL's compiler already contains structured data about the query. We'd like to\noffer transparency to tools which use PRQL, so they can offer lineage\ninformation, such as which tables are queried, and a DAG of transformations for\neach column.\n\n{{< /columns >}}\n\n## Long term\n\n{{< columns >}}\n\n#### SQL-to-PRQL conversion\n\nWhile PRQL already allows for a gradual on-ramp — there's no need to switch\neverything to PRQL right away — it would also be useful to be able to convert\nexisting SQL queries to PRQL, rather than having to rewrite them manually. For\nmany queries, this should be fairly easy. (For some it will be very difficult,\nbut we can start with the easy ones...)\n\n#### Language\n\nWhile the core semantics and syntax of the language are now fairly stable, we\nare planning\n[a few major features](https://github.com/PRQL/prql/issues?q=is%3Aopen+is%3Aissue+label%3Amajor-feature+label%3Alanguage-design)\nthat will give PRQL the feeling of a real programming language and elevate it in\n[the chomsky hierarchy](https://en.wikipedia.org/wiki/Chomsky_hierarchy).\nHonorable mentions here are recursive CTEs (or rather functions), algebraic type\nsystem, pre-specified join conditions and regex.\n\nNote that these features will probably inflict breaking changes with each minor\nrelease before we stabilize the 1.0, the first indefinitely supported language\nedition.\n\n<--->\n\n#### Alternative backends\n\nCurrently, PRQL only transpiles into SQL, using connectors such as DuckDB to\naccess other formats, such as Pandas dataframes. But PRQL can be much more\ngeneral than SQL — we could directly compile to any relational backend, offering\nmore flexibility and performance — and a consistent experience for those who use\nmultiple tools.\n\nFor example, we could compile PRQL to RQ (Relational Query intermediate\nrepresentation) and then use that to apply the transformations to an in-memory\ndataframe of a performance-optimized library (such as\n[Polars](https://www.pola.rs/)) or a Google Sheets spreadsheet. Alternatively,\nwe could even convert RQ to [Substrait](https://substrait.io/).\n\n### PRQL IDE\n\nWe'd like to make it easier to try PRQL. We currently have the playground, which\ncompiles PRQL and runs queries with a DuckDB wasm module, but there's much more\nwe could do. Could we support for importing arbitrary CSV and parquet input\nfiles and then exporting the results? Could it integrate an LSP?\n\nWe can balance this against building integrations with existing tools.\n\n{{< /columns >}}\n\n## Not in focus\n\nWe should focus on solving a distinct problem really well. PRQL's goal is to\nmake reading and writing analytical queries easier, and so for the moment that\nmeans putting some things out of scope:\n\n- Building infrastructure outside of queries, like lineage. dbt is excellent at\n  that! ([#13](https://github.com/PRQL/prql/issues/13)).\n- Writing DDL / index / schema manipulation / inserting data\n  ([#16](https://github.com/PRQL/prql/issues/16)).\n"
