Hi, I've just stumbled across the Mimer SQL Validator (commercial product): http://developer.mimer.com/validator/ Not that I know it...Anyway, there are different things (like PHP scripts or stored procedures and such), which do a whole lot of other logic and/or processing which influences the queries they finally make. So I think such SQL checkers are not that useful. Might be just MHO, though.
