Wordpressは、重複する記事のSQLステートメントをすばやく削除します

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'
