mysql 根据 select 语句从同一个 table 中删除

Question

我真是绕轴了
我正在尝试从 table.
中删除一些记录这行不通...

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

...所以我选择了临时 table 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;

... 仅当运行作为 root 时才有效。如果我运行作为所需的用户，无论我给用户多少权限，我都会被拒绝访问。
我尝试添加 CREATE、DROP、INSERT、DELETE，SELECT，但仍然无法访问。
但是当我尝试为用户提供 CREATE TEMPORARY TABLES 访问权限时，我得到 ...

ERROR 1144 (42000): Illegal GRANT/REVOKE command

我在 Linux.MySQL 上安装了 MySQL 版本 5.5.14 运行ning 任何帮助将不胜感激！

您还可以将您的原始查询表述为 join:

DELETE t
FROM table t
JOIN (SELECT id FROM table WHERE ...) todelete ON t.id = todelete.id
