The tuple of SID=5 doesnot statisfy the condition as given in the question hence I am unclear with the required output. However, here is my answer that lists the tuples with the salesamount > Avg(salesamount) A bit complex, but lets go step by step: Step1: Fetch all the saleids and sids from the sale table SELECT S1.SID, S1.SALEID FROM SALE S1 ORDER BY SID Step 2: Lets fetch the prodid and quantity corresponding to every saleid SELECT S1.SID, S1.SALEID, S2.PRODID, S2.QUANTITY FROM SALE S1, SALEDETAIL S2 WHERE S1.SALEID=S2.SALEID ORDER BY S1.SID Step 3: Now lets calculate the amount generated with every sale SELECT S1.SID, S1.SALEID, S2.PRODID, S2.QUANTITY,(P.PRICE*S2.QUANTITY) AMOUNT FROM SALE S1, SALEDETAIL S2, PRODUCT P WHERE S1.SALEID=S2.SALEID AND S2.PRODID = P.PRODID ORDER BY S1.SID Step 4: Similarly lets also calculate the discount amount SELECT S1.SID, S1.SALEID, S2.PRODID, S2.QUANTITY,(P.PRICE*S2.QUANTITY) AMOUNT, ((P.PRICE*S2.QUANTITY)*(P.DISCOUNT/100)) DISCOUNT FROM SALE S1, SALEDETAIL S2, PRODUCT P WHERE S1.SALEID=S2.SALEID AND S2.PRODID = P.PRODID ORDER BY S1.SID Step 4: Now lets replace the amount and discount columns with a single 'Total amount' column SELECT S1.SID, S1.SALEID, S2.PRODID, S2.QUANTITY,((P.PRICE*S2.QUANTITY)*((100-P.DISCOUNT)/100)) TOTALAMOUNT FROM SALE S1, SALEDETAIL S2, PRODUCT P WHERE S1.SALEID=S2.SALEID AND S2.PRODID = P.PRODID ORDER BY S1.SID Step 5: Now we will calculate the total sum of amount generated by EVERY salesman. To do it, we will "group by" SID and calculate the sum of total amount generated in the previous step. SELECT S1.SID, SUM(((P.PRICE*S2.QUANTITY)*((100-P.DISCOUNT)/100))) TOTALAMOUNT FROM SALE S1, SALEDETAIL S2, PRODUCT P WHERE S1.SALEID=S2.SALEID AND S2.PRODID = P.PRODID GROUP BY S1.SID ORDER BY S1.SID Step 6: Now lets calculate the average sales amount of all sales made We will use AVG Function on TOTAL AMOUNT calculated in Step 5 Incorrect Query: SELECT AVG(((P.PRICE*S2.QUANTITY)*((100-P.DISCOUNT)/100))) AVGAMOUNT FROM SALE S1, SALEDETAIL S2, PRODUCT P WHERE S1.SALEID=S2.SALEID AND S2.PRODID = P.PRODID Incorrect Query: SELECT AVG(SUM(((P.PRICE*S2.QUANTITY)*((100-P.DISCOUNT)/100)))) TOTALAMOUNT FROM SALE S1, SALEDETAIL S2, PRODUCT P WHERE S1.SALEID=S2.SALEID AND S2.PRODID = P.PRODID GROUP BY S1.SID Actual Correct Way to calculate average: SELECT SUM(SUM(((P.PRICE*S2.QUANTITY)*((100-P.DISCOUNT)/100)))/SUM(S2.QUANTITY)) TOTALAMOUNT FROM SALE S1, SALEDETAIL S2, PRODUCT P WHERE S1.SALEID=S2.SALEID AND S2.PRODID = P.PRODID GROUP BY S1.SID Step 7: Now we will only select those SID's that have a total amount > Average To do this, we will have to combine query in Step 6 with step 7 SELECT SID, SNAME, LOCATION FROM SALESMAN WHERE SID IN (SELECT SID FROM (SELECT S1.SID, SUM(((P.PRICE*S2.QUANTITY)*((100-P.DISCOUNT)/100))) TOTALAMOUNT FROM SALE S1, SALEDETAIL S2, PRODUCT P WHERE S1.SALEID=S2.SALEID AND S2.PRODID = P.PRODID GROUP BY S1.SID ORDER BY S1.SID) WHERE TOTALAMOUNT> (SELECT SUM(SUM(((P.PRICE*S2.QUANTITY)*((100-P.DISCOUNT)/100)))/SUM(S2.QUANTITY)) TOTALAMOUNT FROM SALE S1, SALEDETAIL S2, PRODUCT P WHERE S1.SALEID=S2.SALEID AND S2.PRODID = P.PRODID GROUP BY S1.SID) ) ================================================ FILE: DBMS/Day-6/Exercise-63.txt ================================================ SELECT P.PRODID, P.CATEGORY, P.PDESC, P.PRICE FROM PRODUCT P WHERE PRICE = (SELECT MAX(PRICE) FROM PRODUCT WHERE CATEGORY=P.CATEGORY); ================================================ FILE: DBMS/Day-6/Exercise-64.txt ================================================ SELECT SNAME FROM SALESMAN S WHERE NOT EXISTS(SELECT SID FROM SALE S1 WHERE S1.SID=S.SID) ================================================ FILE: DBMS/Day-6/Exercise-65.txt ================================================ SELECT SNAME FROM SALESMAN S WHERE EXISTS (SELECT * FROM SALE S1 WHERE S.SID=S1.SID AND TO_CHAR(S1.SLDATE, 'MM-YY')='06-15') ================================================ FILE: DBMS/Day-6/Exercise-66.txt ================================================ Display SId, SName and Location -> SELECT S.SID, S.SNAME, S.LOCATION of those salesmen -> FROM SALESMAN S WHERE S.SID IN () who have total sales amount -> SUM(individual salesamount) greater than -> '>' average total sales amount -> SUM(individual-salesamount)/SUM(total-quantity) of their location -> location-wise 'GROUP BY location' calculated per salesman.

It was amazingly useful for quick revision during my Power Programmer Interview Preparation. ___ ```Hey there everyone!``` Glad to have you here. Looking for resources for InfyTQ? Well, you are at the right place. I am Omkar Deshpande and this is my github repo consisting of all the solutions to InfyTQ. I prepared this while I was preparing for InfyTQ exam back in June 2019. I always had to go back and check my solutions for revision, so instead thought to make a github repo, which is mobile handy and can also be used by others looking for a reference. I would soon be uploading a blog on how I was able to ***crack the Power Programmer Interview*** and got selected for a Power Programmer Role at Infosys. I would mention all the resources used. Remember, the best resource available is your will-power! Donot rely on any paid courses or online services, and work on yourself every single day with consistency, and I am sure you would land at your dream job! Further, I request you to please also update me the changes/incorrect/updations in this Solutions Repository. I would love to include your solutions/alternatives within this repo. Lets make this repo more and more generalised for the students preparing on InfyTQ platform. ###### General Information on InfyTQ InfyTQ is a free platform open to all engineering students in their third and fourth year across India. The platform encourages holistic development by imparting technical as well as professional skills and help them become industry ready. I started this course on **June 15th 2019**. The platform consists of various assignments with rising difficulty levels. I am presenting my solutions to all the assignments in the InfyTQ platform. So go ahead and **fork** this repo and include your efficient solutions! https://infytq.infosys.com - automatic! [InfyTQ](https://infytq.infosys.com) #### Would love to include your solutions into this repo! _Happy reviewing! :octocat:_ ================================================ FILE: _config.yml ================================================ theme: jekyll-theme-cayman
