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特定的吗?
最佳答案
您可以这样使用SQL:
DELETE FROM ContactHostCommand
USING `contact_hostcommands_relation` AS ContactHostCommand
WHERE (ContactHostCommand.`chr_id` = 999999)
LIMIT 1
