Hi Vlad! What do you know about how VFP handles SQL internally? Right, nothing (the same apply to me too ;). I know how to speed up SQL with Rushmore (if it's simple), but I know nothing about how VFP handles Union clause or nested selects. May be it's my personal habit, but I like do calculation process step-by-step, it could be more understandable after two-three month...;))), After all, this doesn't matter ;) * Will write login scripts for food >Why are you so sure?
