    If I understand correctly, that may be the problem... no indexes on the columns you're working with.

    If you could gen and capture an actual execution plan, I'm sure someone here would be able to make a better recommendation as to what your plight may be.

    Many people here are very good with execution plans. It is likely due to the indexes as Jeff has said.
