well you could use that query to select the user id's then use two delete
queries one for user table based off the id, one for user meta based off of
user id. So exactly simple single query but it works. Also if you intend
to use this in a plugin on not directly on the database you could use
wp_delete_user() which deletes the user and user meta for the user id, you
