从“表”中删除为“别名” ...在“别名。列”中...为什么语法错误?

mysql

我尝试使用MySQL:

DELETE FROM `contact_hostcommands_relation` AS `ContactHostCommand` WHERE (`ContactHostCommand`.`chr_id` = 999999) LIMIT 1

我得到这个:

#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'WHERE (`ContactHostCommand`.`chr_id` = 999999) LIMIT 1' at line 1

注意: 此查询是自动生成的,条件基于表别名。

为什么会出现此错误?

有什么方法可以在where子句中使用表别名?

这是MySQL特有的吗?

您可以这样使用SQL:

DELETE FROM ContactHostCommand 
USING `contact_hostcommands_relation` AS ContactHostCommand 
WHERE (ContactHostCommand.`chr_id` = 999999) 
LIMIT 1
