• Nice article, Wagner! Articles of this nature should be required reading for anyone just starting out in SQL and those that enjoy a refresher. Well done. In the vein of "One picture is worth a thousand words", you did a great job with the graphics. Thanks for taking the time.

    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.
