用WordPress做采集站的朋友，遇到最大的问题就是文章会重复，这时，我们就需要将重复的文章进行去重处理，如何能方便快捷的一次性删除WordPress重复标题的文章呢？下面小牛云站长就给大家介绍两种一次性去除标题重复文章方法：

使用方法：

只需将下面的SQL语句，放到自己网站数据库的 SQL框里，然后执行就可以了。

1、去除重复文章，只保留一篇

CREATE TABLE my_tmp AS SELECT MIN(ID) AS col1 FROM wp_posts GROUP BY post_title; DELETE FROM wp_posts WHERE ID NOT IN (SELECT col1 FROM my_tmp); DROP TABLE my_tmp;

2、去除重复文章，一片都不保留

CREATE TABLE my_tmp AS Select ID AS col1 From wp_posts Where post_title In (Select post_title From wp_posts Group By post_title Having Count(*)>2); DELETE FROM wp_posts WHERE ID IN (SELECT col1 FROM my_tmp); DROP TABLE my_tmp;
