in thread How to structure applications using a RDBMS
I don't disagree a bit with what you've said.
On the other hand, I think a developer shouldn't have to be told more than twice that:
can eat up a couple hundred gig of spool without blinking, but thatSELECT DISTINCT(item) FROM a.table
goes by in the blink of an eye. You'd think that wouldn't be a major paradigm shift for them--but it is (okay, in one case I've been dwelling on lately). And it'd be even nicer to be heard the first time.SELECT item FROM a.table GROUP BY item
(This is an oversimplified example--the point being DISTINCT versus GROUP BY.)
