Just keep in mind that JOIN in the most simple form shows only those rows that match on the joining criteria on both tables. Occasionally you’ll want to show rows even when items are missing from one table (example: a users table with optional information, maybe the addresses are normalized in a separate table because there are more than one type of address). Unfortunately I know these well enough to recognize them but never well enough to remember whether they are the LEFT, RIGHT, INNER, or OUTER joins.

Two excellent books for getting into databases (sounds like you are) are “Databases for Mortals” and the introductory book by Joe Celko (sorry don’t remember the title).

Hey, thanks for posting that. I think it’s always so helpful when people post their revelations during the learning/struggling phase with technology. At the very least it is their for posterity and at the best it helps others (aka me).

Thanks again.

Thank you SO much for the info on streaming CSV data directly to the browser. Can’t tell you how much time I wasted on the plethora of examples utilizing files stored on the server.

The cache control trick was the clincher - nobody else mentions it that i’m aware of.

Thanks again,
