Laravel多表原始查询到Eloquent

Question

SELECT * FROM 
    (
    SELECT t1.personId 
    FROM 
     (
     SELECT * FROM `skills` 
     WHERE `title` = 'SaaS' 
     GROUP BY `personId` 
    ) t1 
     INNER JOIN 
     (
     SELECT * FROM `languages` 
     WHERE `title` = 'English' 
     GROUP BY `personId` 
    ) t2 
     INNER JOIN 
     (
     SELECT * FROM `education` 
     WHERE `title` = 'Louisiana State University' 
     GROUP BY `personId` 
    ) t3 ON t1.personId = t2.personId AND t2.personId = t3.personId 
) tr 
    LEFT JOIN `people` ON people.id = tr.personId 

如何将此Sql字符串转换为Laravel Eloquert或DB查询？

Answer 1

不是测试，但尝试，让看看怎么回事

DB::table('tr')->select("tr.*") 
->from("(
    SELECT t1.personId 
    FROM 
     (
     SELECT * FROM `skills` 
     WHERE `title` = 'SaaS' 
     GROUP BY `personId` 
    ) t1 
     INNER JOIN 
     (
     SELECT * FROM `languages` 
     WHERE `title` = 'English' 
     GROUP BY `personId` 
    ) t2 
     INNER JOIN 
     (
     SELECT * FROM `education` 
     WHERE `title` = 'Louisiana State University' 
     GROUP BY `personId` 
    ) t3 ON t1.personId = t2.personId AND t2.personId = t3.personId 
) as tr") 
->leftJoin('people','people.id','=','tr.personId') 
->get();

我实现了这样的事情和工作..

   $this->SalesGroup_model->select('sales_group.id','sales_group.name','sales_group.from_weight','sales_group.to_weight','sales_group.amount',DB::raw("sum(sales_item.net_weight) as total_sales")) 
        ->leftJoin('sales_item',function($join){ 
         $join->on('sales_item.net_weight','>=','sales_group.from_weight'); 
         $join->on('sales_item.deleted','=',DB::raw('"0"')); 
        }) 
        ->groupBy('sales_group.id'); 
       $object = DB::table(DB::raw("({$sub->toSql()}) as one")) 
       ->mergeBindings($sub->getQuery()) 
       ->join(DB::raw('(SELECT sales_group.id, 
        count(mysales.employee_id) AS "total_person" 
         FROM `sales_group` 
         LEFT JOIN 
          (SELECT sales_item.net_weight, 
          sales_challan.employee_id 
          FROM sales_item 
          INNER JOIN sales_challan ON sales_challan.id=sales_item.challans_id 
          GROUP BY sales_item.challans_id, 
          sales_challan.employee_id) mysales ON mysales.net_weight>=sales_group.from_weight 
          AND mysales.net_weight<=sales_group.to_weight 
          GROUP BY sales_group.id) two'),function($join){ 
          $join->on('two.id','=','one.id'); 
       })->get();
