mysql - 如果该行具有特定值，则从 MYSQL 中删除该行

Question

如果行中的两列在其列中具有最大值，我将尝试删除行。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。我尝试从上面的查询中执行的操作是，如果第二个和第三个在其列中具有最大值，则尝试删除行。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);
