I want the DISTINCT to ignore the f1 column completely. But I want all 3 cols. ie. the entire row selected though. Pretend that f1 is a unique PK it'll always be different, I want to DISTINCT to ignore it, so if 2 or mores row have dup f2 *and* f3 Distinct will let only one through. > Are there other columns (beyond these 3) to move as well?
