I'm pretty sure it can be done with a single query, using joins and an embedded select. I just haven't played around with it much yet. Just wondering if anyone else had anything similar.

EDIT: Got it worked out.

This worked for me to update all the old post titles to "Re: [thread title]" if they were currently blank. If you have a lot of posts this can take a while to execute. I have about 365k posts and it took about 10 minutes.

The query:

Code:

UPDATE post SET post.title = concat("Re: ",(SELECT thread.title FROM thread WHERE thread.threadid = post.threadid)) WHERE post.title = ""
