Question

我真的缠在轴上。
我试图从表中删除一些记录这不起作用......

delete from table where id in (select id from table where ...

...因为我得到了可怕的......

ERROR 1093 (HY000) at line 1: You can't specify target table for update in FROM clause

...所以我去了临时表选项......

create temporary table idTemp (idt bigint(20) unsigned); insert into idTemp select id from table where [...]; delete from table where id in (select idt from idTemp); drop table idTemp;

...仅在以root身份运行时才有效。如果我作为所需的用户运行，无论我给用户多少特权，我都会获得ACCESS DENIED 我尝试添加CREATE，DROP，INSERT，DELETE，SELECT并仍然获得ACCESS DENIED 但是当我尝试给用户CREATE TEMPORARY TABLES访问时，我得到了......

ERROR 1144 (42000): Illegal GRANT/REVOKE command

我在Linux上运行MySQL版本5.5.14 任何帮助将不胜感激！

Answer 2

您还可以将原始查询标记为join：

delete t
    from table t join
         (select id from table where ...
         ) todelete
         on t.id = todelete.id;

mysql基于select语句从同一个表中删除
