Only 10,000 records?
How well is the DB organized?
Is this an established DB to which you are "inserting" records?

If you can understand the "logic" of the SQL optimizer, you can "see" what it is looking for.... It can only guess, but if you know that a better route is available, then you can influence it into picking that better one....
