使用限制删除SQL查询

Question

我有这个查询

DELETE c FROM review_comments AS c 
LEFT JOIN users AS u 
ON u.user_id = c.user_id
WHERE c.comment = '{$comment}'
AND u.username = '{$user}'
LIMIT 1;

在我删除LIMIT 1;

之前，它无效

它说：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 'LIMIT 1' at line 6

在这种情况下，这是LIMIT 1的错误用法吗？我有一个相同的查询没有连接表，LIMIT 1工作得很好？

Answer 1

我认为LIMIT不能用于MySQL中的多表引用DELETE语句。
