SQL query to find/repalce post text in a specific forum

Hello,

I am trying use a sql query to find and replace a certain word in a specific forum.

I tried the following but that did not work.

Code:

UPDATE post SET pagetext = REPLACE(pagetext, 'oldtext', 'newtext') WHERE forumid='435'

Here is the error:
An error occurred while attempting to execute your query. The following information was returned.
error number: 1054
error desc: Unknown column 'forumid' in 'where clause'

Any help is appreciated. Thank you.

Well, as the error says, there is no forumid column in the post table. You would need to join with the thread table (post.threadid = thread.threadid) in order to get the forumid (thread.forumid).

That worked like a charm! Thanks a lot.

Some questions:

1. What if I want to replace multiple words?
2. For multiple Child forums, is it possible to select a parent forum?

This will cut down a lot of time for me.

Thanks again.

Code:

UPDATE post

        SET pagetext = REPLACE(pagetext, 'oldtext', 'newtext')

                WHERE (SELECT forumid FROM thread WHERE thread.threadid = post.threadid) = (SELECT forumid FROM forum WHERE parentid = 435)

Where 435 can be swapped out for another 'parent' forum.
