I would expect that UNIQUE first sorts the data in order to trim out the duplicates. It's the most efficient way to find and remove them. Which is why I went looking for it in SORT first. I doubt that issuing SORT and UNIQUE in any combination is faster because of the redundancy. I could be wrong, though... -- Sincerely, | For long you live and high you fly.
