为什么当我放入 Laravel 时，我的 sql 查询会出现此错误

问题描述

 $personalSale = DB::select(DB::raw("SELECT *
        FROM purchases a
        WHERE a.purchase_status IN (3001,3002,3003,4000,4001,4002,4003) AND 
        a.purchase_date LIKE "%12/2020" AND
        (a.user_id = 50 OR a.user_id in (SELECT b.user_id
        FROM user_infos b
        WHERE b.referrer_id = 1911000140))
        ORDER BY a.purchase_amount DESC
        LIMIT 10;
        "));

错误： 语法错误，意外的 '" AND ' (T_CONSTANT_ENCAPSED_STRING)，需要 ',' 或 ')'

解决方法

LIKE "%12/2020" 尝试将 " 替换为 '
