mysql - #1064 在 WordPress 中删除重复行时出错

Question

我正在尝试从 WordPress 表中删除重复行，但收到​​ 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

任何人都可以帮我解决这个问题吗？

提前谢谢您。

删除 Alias 以不同的方式进行。

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