mysql - #1064 在 wordpress 中删除重复行时出错

Question

我正在尝试从 wordpress 表中删除重复的行，但出现 sql 错误

#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 'a, wp_posts b WHERE a.ID > b.ID AND a.post_title = b.post_title' at line 1

像这样，我的查询是

DELETE FROM wp_posts a, wp_posts b WHERE a.ID > b.ID AND a.post_title = b.post_title

谁能帮我解决这个问题。

先感谢您。

Answer 1

Delete 以不同的方式执行 Alias。

DELETE FROM a USING wp_posts a, wp_posts b 
WHERE a.ID > b.ID AND a.post_title = b.post_title

为回答我的问题感到内疚。反正我发现了一个错误，

我的查询应该是，

DELETE a FROM  wp_posts a, wp_posts b WHERE a.ID > b.ID AND a.post_title = b.post_title;

像这样。
