从mysql表中删除值不相似的行

Question

我有一张有测试结果的表格 它看起来像：

Test    | Result
Math    | Pass
Science | Fail
History | cancelled
French  | Absent

该表名为table1。我想删除表格中列值结果不是"Pass"或"fail"

的行

类似的东西：

Delete from table1
where result not in (Pass, Fail);

结果表格如下：

Test    | Result
Math    | Pass
Science | Fail

Answer 1

试试这个：

DELETE FROM table1 WHERE result NOT IN ('Pass', 'Fail');

Answer 2

您的示例通过在Pass和Fail周围添加引号为我工作。

delete from table1
where result not in ('Pass', 'Fail')
