I had orphaned comments too (and didn't know to)</p>Andrea OlivatoThu, 19 Nov 2009 05:08:00 -0000http://blog.andreaolivato.net/wordpress/clean-wordpress-database-removing-empty-categories.html#comment-23521815<p>Thanks so MUCH for this post. I had a stack of tags get autogenerated by a plugin gone nuts, and ended up with over 5000 tags.. made WP sooooo slow. This fixed it for me.. I probably COULD have worked it out but Google found you first!</p><p>A favour in return: I had a stack of comments laying around from posts that I had deleted. The following SQL allows you to find orphaned comments</p><p>SELECT * FROM `wp__comments` <br>WHERE NOT EXISTS (SELECT ID from wp_posts where wp_comments.comment_post_ID = wp_posts.ID)</p><p></p>Steve "The IT Juggler" OllisThu, 19 Nov 2009 05:05:54 -0000
