I would have designed the db differently:

Give all partners and ID (numeric). On insert into your join table of partner1, partner2 always make sure they are in numeric order ie if you have partner 1 and 2 always put 1 in the first column if its partners 2 and 1 then you put 1 in the first col and 2 in the second and so on for all the columns you need.

Then to get the unique combinations of partnesr all you need to do is:

Select distinct col1, col1.... from table.

Hope this helps.
