从wp_post表中删除ID

Question

我使用此SQL查询为我获取所有没有照片的帖子，它向我显示2010年的帖子，但是使用SQL命令可以删除这些2010年的帖子

SELECT * FROM wp_posts LEFT JOIN wp_posts ON
(wp_posts.ID = wp_postmeta.post_id AND wp_postmeta.meta_key = '_thumbnail_id')
WHERE 1 = 1 AND (wp_postmeta.post_id IS NULL) AND wp_posts.post_type = 'post'
AND (wp_posts.post_status = 'publish' OR wp_posts.post_status = 'private')
GROUP BY wp_posts.ID ORDER BY wp_posts.post_date

Answer 1

一个选项将使用EXISTS：

DELETE FROM wp_posts 
 WHERE EXISTS 
    (
    SELECT 1
      FROM wp_posts wp1
      LEFT JOIN wp_postmeta wp2 ON wp1.ID = wp2.post_id AND wp2.meta_key = '_thumbnail_id'
     WHERE wp2.post_id IS NULL
       AND wp1.post_type = 'post'
       AND (wp1.post_status = 'publish' OR wp1.post_status = 'private')
       AND wp1.ID = wp_posts.ID
     GROUP BY wp1.ID
     )
