Hi there,

I know this is a question for the mysql mailing list, but maybe one of you guys also could help out with that.

I do have to tables (users, messages). Now there unfortunatelly are some messages where the sender in the user table is missing.

I am trying to find all messages which do not have the belonging user anymore.

So I tried this:
SELECT m.subject, m.status
FROM user u, messages m
WHERE   m.sender_user_id != u.user_id

But this returns far to many rows.

Has anybody an idea how to do that?

Thank you in advance,
