  • Speaking of automated testing, you should write a followup article about who tests the automated test software?  I can't speak for anyone else but we've had the occasional "whoops" occur even there.  In the panic that followed to fix the test software so they could meet a deadline, they fixed the original "whoops" and introduced another that was just as difficult to find and fix.

    BTW... +10,000,000 for pointing out that even the Actual Execution Plan is NOT a measure of performance.  People just don't seem to get that especially when they're comparing two execution plans.

    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.
