Thank you!

Very useful post.

Although I couldn´t get this query to work

SELECT * From wp_terms wt
INNER JOIN wp_term_taxonomy wtt ON wt.term_id=wtt.term_id WHERE wtt.taxonomy='post_tag' AND wtt.count=0;

MySQL returns nothing ( it should )

Do you know a query to reset WP data to it's original form, this includes removing all dummy content and postmetas?

Several of these queries are awesome for post host transfer updates. I know you change the URL via admin before moving it etc, but these are nice too! Thanks!

Hello All.
Came across the site from google and though it has a lot of queries, I still can't find the one I'm looking for and i'm hoping someone might help.
What I'm trying to do, is delete a user and all posts related to that user. I ran "DELETE FROM `impactra_wrdpn`.`wp_users` WHERE `wp_users`.`ID` = theuserid" though user got deleted, the posts were still on the site. I know I could do it from admin backend but my allocation is not allowing me and these are all spam posts :(
Please advice and Thanks in advance
Samuel

I have used your queries before many times but only when moving wordpress sites/databases around on external hotsing not to my Ubuntu server which is what I want to do now. Normally goes well - just create a new site and database - import the old sql file to create the tables and then run the queries - in this case primarily changing http://www.myoldhostname.co.uk to http://localhost.
In the past when I have run the site for the first time with the new structure it goes straight in but this time I am being given the WordPress Welcome screen. Any thoughts. wp-config is correct becasue I delete all the newly created tables before importing the old sql file.
