Question

我的MySql函数继续给我语法错误消息：

SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in 
 your SQL syntax; check the manual that corresponds to your MySQL server version 
 for the right syntax to use near 'SELECT SUM(sell_rate) FROM (SELECT 
 COUNT(stock_id)*stock_rate sell_rate 
 FRO' at line 2 (SQL: select 
 SELECT SUM(sell_rate) FROM (SELECT COUNT(stock_id)*stock_rate sell_rate 
 FROM tbl_stock st 
 INNER JOIN tbl_product pdt ON pdt.product_id = st.produck_id 
 WHERE produck_name = 'product_id' lIMIT 6
 GROUP BY stock_id)

  from `tbl_stock`)

我已经检查了所有括号并且它们都已关闭我甚至在MySQL工作台上执行了它并且它很好但是在Laravel它给了我这个错误这是我的功能

private function totalprice( $product_id)
   {
   $selltotal = DB::table('tbl_stock')
   ->select(DB::raw("
    SELECT SUM(sell_rate) FROM (SELECT COUNT(stock_id)*stock_rate sell_rate 
    FROM tbl_stock st 
    INNER JOIN tbl_product pdt ON pdt.product_id = st.produck_id 
        WHERE produck_name = 'product_id' lIMIT 6
    GROUP BY stock_id)

    "))->get();
  return $selltotal;
   }

Answer 1

尝试DB::selet()：

$selltotal = DB::select("SELECT SUM(sell_rate) FROM (SELECT COUNT(stock_id)*stock_rate sell_rate 
FROM tbl_stock st 
INNER JOIN tbl_product pdt ON pdt.product_id = st.produck_id 
  WHERE produck_name = 'product_id' lIMIT 6)
GROUP BY stock_id");

Answer 2

不要使用SELECT，只需尝试DB ::语句。您还缺少应在LIMIT 6

之后的右括号

$selltotal = DB::statement("SELECT SUM(sell_rate)
      FROM
          (SELECT COUNT(stock_id) * stock_rate sell_rate
           FROM tbl_stock st
             INNER JOIN tbl_product pdt ON pdt.product_id = st.produck_id
           WHERE produck_name = 'product_id'
           LIMIT 6)
        GROUP BY stock_id");
