Whew! That solves it! No need for numbers, they are sub milli-second now! Can't the SQL optimiser do this automatically? Is this a derby specific problem? (Sorry for amateurish questions; this is my first real db application) I ask because I have another application where I programmatically generate queries, and the former type of query is easier to generate than the one you suggested. I always assumed that the SQL optimiser will "flatten" the query... Thanks, Harshad
