Well, prior to the SVN, most SQL updates were posted directly in the changelog and you can still see most of those here:
http://code.google.com/p/projecteqem.../changelog.txt
Even since the SVN, some required SQL has still been added only in the changelog, so you will need to make sure you are caught up there as well.
If you don't have custom stuff in your database, you are probably best off just downloading the latest PEQ database and wipe your existing DB out and replace it with the current PEQ one. Otherwise, you are going to have quite a bit of DB work to get fully caught up. If that is not an option, then you may want to download the latest PEQ DB and go table by table and make sure your DB matches up with PEQ by creating or adjusting fields as needed.
