刪除重複的帖子在WordPress

Question

我想從我的WordPress網站 刪除重複的職位選擇重複的崗位工作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' 

這是錯誤消息：

意外標記（接近a）意外標記（接近。）意外標記 （接近*）

第一個SELECT發帖ID。然後使用DELETE聲明與WHERE IN子句。

注意：在執行整個查詢之前，測試IN()子句中的子查詢是否返回正確的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' 
)
