Rebuild user post counts (query) 1.x

This will recalculate and update the post counts for all users at once. This is a large query that may take a while to finish.

Code:

UPDATE xf_user AS user
SET message_count = (
	SELECT COUNT(*)
	FROM xf_post AS post
	LEFT JOIN xf_thread AS thread ON (thread.thread_id = post.thread_id)
	WHERE post.user_id = user.user_id
	AND post.message_state = 'visible' AND thread.discussion_state = 'visible'
	GROUP BY post.user_id
);

If you have forums you wish to exclude from the count then use this query, where 1,2,3 is a comma-list of node_ids that are excluded from the count:

Code:

UPDATE xf_user AS user
SET message_count = (
	SELECT COUNT(*)
	FROM xf_post AS post
	LEFT JOIN xf_thread AS thread ON (thread.thread_id = post.thread_id)
	WHERE post.user_id = user.user_id
	AND thread.node_id NOT IN (1,2,3)
	AND post.message_state = 'visible' AND thread.discussion_state = 'visible'
	GROUP BY post.user_id
);

Backup first.

Because this query is so large you may encounter errors relating to these MySQL settings:

wait_timeout
innodb_lock_wait_timeout

You need to ask your host or server person to increase these settings if you encounter such errors.
