# EsParser
php的操作类库，通过写sql来转化dsl来查询elasticsearch
### composer使用
    {
        "require": {
            "qieangel2013/esparser": "dev-master"
        }
    }
    composer install
    require __DIR__.'/vendor/autoload.php';
    //$sql = 'select * from alp_dish_sales_saas where sid in(994,290) limit 1,10';
    //$sql='update alp_dish_sales_saas set mid=3  where adsid=15125110';
    //$sql='delete from alp_dish_sales_saas where adsid=15546509';
    //$sql="select *,concat_ws('_',category_name.keyword,dish_name.keyword,sku_name.keyword) as dfg from alp_dish_sales_saas where sale_date>'2017-01-01' and sale_date<'2017-09-02' group by dfg order by total_count desc";
    //$sql = 'select *,DATE_FORMAT(sale_date,"%Y-%m-%d") as days from alp_dish_sales_saas group by days ';
    $sql="insert into test(`id`,`name`)values(9,'zz')";
    $sql2="insert into test(`id`,`name`)values(9,'zz')";
    $es_config=array(
	    'index' =>"alp_dish_sales_saas",
	    'type'  =>"alp_dish_sales_saas",
	    'url'   =>"http://127.0.0.1:9200",
        'version' =>"5.x" //1.x 2.x 5.x 6.x 7.x,可以不配置，系统会请求获取版本，这样会多一次请求,建议配置一下
	 );
    $parser = new EsParser($sql, true,$es_config);//第三个参数是es的配置参数，一定要配置
    print_r($parser->build());//打印结果
    print_r($parser->setSql($sql2)->build());//打印结果
    $result=$parser->scroll();//深度分页初始化会返回第一条
    $result=json_decode($result,true);
    print_r($result);//打印深度分页结果
    $result1=$parser->scroll($result['scrollid']);//深度分页下一页
    print_r(json_decode($result1,true));//打印深度分页结果
    $result2=$parser->scroll($result['scrollid']);//深度分页下一页
    print_r(json_decode($result2,true));//打印深度分页结果
    $result3=$parser->scroll($result['scrollid']);//深度分页下一页
    print_r(json_decode($result3,true));//打印深度分页结果
    //print_r($parser->explain());//打印dsl

    	);
	$parser = new EsParser($sql, true,$es_config);//第三个参数是es的配置参数，一定要配置
	print_r($parser->build());//打印结果
