    WOW, over my head on the first post. OK, I'll just grab the popcorn and sit back and absorb.

    Heh... I'll summarize. In fact, it's already on a T-Shirt... "NULLs don't mean 'Nothing'". 😉 At least not in an RDBMS.

    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.
