    So, I did a little playing around myself, and discovered that as far as performance goes there is zero difference. At least with the size data set that I was using.

    How many rows was that? I ask because I can see the first query taking twice as long if something is found.

    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.
