> Now I've spoon fed you Damn, Neil...you're a d-bag. Next time you go to offer "help," it may assist you to know that most people don't respond well to being talked down to. (obviously, I'm contradicting my own advice, here; but, I doubt you'll learn from it, anyways) Now, Ron... I'm hoping the following can add a few extra tidbits for you over what Matt already explained. The initial error, I think, was an assumption that natural or spoken language translates directly into SQL. Or, that you'd say: "does variable equal 1 or 2." Makes sense to us, right? ;) Now, I could be wrong about that. But, regardless, SQL read your query as: "(does variable equal 1) or (is 2 non-zero)." And, off course, 2 isn't 0...so that'll always return true; making the 'OR' return true as well. You'll have to associate the variable with each possible match: "WHERE (variable = 1) OR (variable = 2)" Or simplify it, as Matt suggested, using IN: "WHERE variable IN (1, 2)" Did that help any? - Jon L.
