it is all about logic 1 AND 1 = 1 (0 AND 1 ) OR (1 AND 0) OR (0 AND 0) = 0 (0 OR 0) = 0 (1 OR 1) AND (1 OR 0) AND (0 OR 1) = 1 AND OR -------- ------- 0 - 0 0 0 - 0 0 1 - 0 0 1 - 0 1 0 - 1 0 0 - 1 1 1 - 1 1 1 - 1 1 When you understand AND and OR now NOT and NOT IN means more meanful WHERE X NOT true WHERE values NOT IN (x,y,z)

I said to write down the question you're talking about, or at least to refer to it. I have no idea what you're trying to say. What question and in what course is this ?
