MYSQL语法不正确[重复]

【中文标题】MYSQL语法不正确[重复]

【英文标题】：MYSQL Syntax incorrect [duplicate]

【发布时间】：2016-01-26 10:40:50

【问题描述】：

我在下面的语句中得到了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 'c JOIN campaignsFroms f ON f.id = c.id JOIN campaignsRaw r ON r.' at line 2的错误

我缺少什么语法？

代码：

DELETE 
    FROM campaigns c
    JOIN campaignsFroms f      ON f.id = c.id
    JOIN campaignsRaw r        ON r.id = c.id
    JOIN campaignsSubjects s   ON s.id = c.id
    JOIN campaignIPTracking ip ON ip.id = c.id
    JOIN campaignTracking ct   ON ct.id = c.id
    WHERE c.id = '1582'

【问题讨论】：

你试过重新输入c JOIN campaignsFroms f ON f.id = c.id JOIN campaignsRaw r ON r.吗？

另一个问题的摘录：a）您不能对主表使用别名（因此必须删除别名c）。 b) 您必须在多表删除中指定要从哪个表中删除，因此该语句应以DELETE campaigns FROM campaigns 开头。

【参考方案1】：

 DELETE c
FROM campaigns c
JOIN campaignsFroms f      ON f.id = c.id
JOIN campaignsRaw r        ON r.id = c.id
JOIN campaignsSubjects s   ON s.id = c.id
JOIN campaignIPTracking ip ON ip.id = c.id
JOIN campaignTracking ct   ON ct.id = c.id
WHERE c.id = '1582'                                 

【讨论】：

你可以使用连接删除吗？？

为什么要投反对票？使用 JOIN 删除的语法是正确的。
