First SELECT
post IDs. Then Use DELETE
statement with WHERE IN
clause.
NOTE: Before executing whole query, test whether sub query in IN()
clause returns correct ids.
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'
)
