This is related to my other question: http://stackoverflow.com/questions/2579249/managing-foreign-keys

I am trying to join the table of matches and non-matches.

So I have a list of interests, a list of users, and a list of user interests.

I want the query to return all interests, whether the user has the interest or not (should be null in that case), only where the user = x. Every time I get the query working its only matching interests that the user specifically has, instead of all interests whether they have it or not.
