Rich, could you please elaborate on SQL queries being based on sets? I never thought of it that way, and would like to hear your related thoughts.
SteveT, In the 1980s, when there were computer magazines such as Byte and Database Administrator (among many others), Joe Celko wrote a monthly database column in one (or more, I forget these details). This lead me to buy and read his books, including 'SQL for Smarties' and its many editions, 'SQL Programming', and 'Thinking in Sets: Auxilliary, Temporal, and Virtual Tables in SQL'. I reccomend his books to answer your questions and give you a sound foundation. Regards, Rich
