如果该行具有特定的值，从MYSQL删除行

Question

我想删除行，如果两行的列在其列中有最大值。或者它同时具有MIN列和MAX列。

BEGIN 
DELETE FROM scores WHERE (second, third) 
IN ((MAX(second),MAX(third))); 
select * from scores; 
END 

我有三列第一，第二和第三。我试图从上面查询，我试图删除行，如果第二和第三有最大值的列。它给了我一个错误。

ERROR 1111 (HY000) at line 70: Invalid use of group function 

我该如何解决这个问题？

您需要单独写两个条件，试试这个：

DELETE s.* FROM scores s 
WHERE second = (SELECT second FROM (SELECT MAX(second) AS second FROM scores) a) 
AND third = (SELECT third FROM (SELECT MAX(third) AS third FROM scores) b);
