如果该行具有特定值，则从MYSQL中删除行

Question

如果行中的两列有最大值，我试图删除Rows。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，第二和第三列。我试图从上面的查询做的，我试图删除行，如果第二个和第三个从其列具有最大值。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？

Answer 1

你需要分别写两个条件，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);
