Yeah, and GOTO is perfectly fine... In the right place.

All my SQL was so dirt-simple, it couldn't have been non ANSI.
select name, skill from applicants where job_id = $job_id

Oh they *MOVED* okay. Now update the Stored Procedures for sub-section A of
your on-line application on the Development box, and try to push the changes
through to the Production Server.
So, which Stored Procedures got changed?
You have to keep track of them all, cuz MS sure doesn't.
>Stored procedures are NOT over head.
They are a *LOT* of painful administrative overhead, and their gains are
mythical, not real.

If I have to change an SQL statement, I know right where it is, right where
it belongs, right in the code.

Do you have *ANY* idea how quickly:
"select * from MyTable" can be parsed and an execution plan selected?!
It's CHUMP CHANGE in time.
*ONLY* if your SQL is so incredibly complicated that you can't even
understand it will the parse/compile time of SQL be a factor in performance.

I'm from Missouri. Show me.

I only have to change one SQL in one location, and everything is fine.
