Finally! Someone get's back to the original subject of my poor ol' hijacked thread! Thanks, Alain. I'll take a look.

You're right Jeff. I can take a hint, so I started a new thread on NULLs.

Very cool... thanks.

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.
