A question: can you not place your data temporarily in a file and use command line tools to get your answer, since the query runs for potentially a very long time? What table contains "data"? Then you can use a subquery.

Plus, having been an admin and system programmer for a long time I would commend code like this to help from a very senior techie. Quadratic time queries may have system wide impacts that affect other processes and users. This is a polite way of me saying if you did this you would incur the wrath of a lot of people. Just saying. If it is your desktop, okay, maybe.
