That is, if you ask for the subset of odd numbers from the set of positive integers, you get all of them back as a set. I don't build the set of odd numbers one element at a time. You define odd numbers with a rule: 'if remainder is one when you divide the number by two, it's odd'. This could test any integer and classify it. SQL isn't a perfect set language any more than FORTRAN is a perfect algebraic language, as we'll see, but when in doubt about something in SQL, ask yourself how you would specify it in terms of sets and you'll probably get the right answer.
