mysql - 从mysql表中删除值不喜欢的行

Question

我有一张包含测试结果的表格。
看起来像：

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

该表名为 table1。我想删除表中列结果的值不是的行"Pass"或"fail"

就像是：

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

结果表如下所示：

Test    | Result
Math    | Pass
Science | Fail

Pass您的示例通过在and周围添加引号对我有用Fail。

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