删除重复的帖子在WordPress

Question

我想从我的WordPress网站 删除重复的职位选择重复的岗位工作currectlly

SELECT a.ID, a.post_title, a.post_type, a.post_status 
    FROM wp_posts AS a 
     INNER JOIN (
      SELECT post_title, MIN(id) AS min_id 
      FROM wp_posts 
      WHERE post_type = 'post' 
      AND post_status = 'publish' 
      GROUP BY post_title 
      HAVING COUNT(*) > 1 
     ) AS b ON b.post_title = a.post_title 
    AND b.min_id <> a.id 
    AND a.post_type = 'post' 
    AND a.post_status = 'publish' 

和

this query that i need has error 
    DELETE a.* 
    FROM wp_posts AS a 
     INNER JOIN (
      SELECT post_title, MIN(id) AS min_id 
      FROM wp_posts 
      WHERE post_type = 'post' 
      AND post_status = 'publish' 
      GROUP BY post_title 
      HAVING COUNT(*) > 1 
     ) AS b ON b.post_title = a.post_title 
    AND b.min_id <> a.id 
    AND a.post_type = 'post' 
    AND a.post_status = 'publish' 

这是错误消息：

意外标记（接近a）意外标记（接近。）意外标记 （接近*）

第一个SELECT发帖ID。然后使用DELETE声明与WHERE IN子句。

注意：在执行整个查询之前，测试IN()子句中的子查询是否返回正确的ID。

DELETE FROM wp_posts 
WHERE ID IN (
    SELECT a.ID 
    FROM wp_posts AS a 
     INNER JOIN (
      SELECT post_title, MIN(id) AS min_id 
      FROM wp_posts 
      WHERE post_type = 'post' 
      AND post_status = 'publish' 
      GROUP BY post_title 
      HAVING COUNT(*) > 1 
     ) AS b ON b.post_title = a.post_title 
    AND b.min_id <> a.id 
    AND a.post_type = 'post' 
    AND a.post_status = 'publish' 
)
