    We got hit by ISNUMERIC early. It will convert text that happens to be valid hexadecimal into a positive hit. So we went to PATINDEX to find values that were numeric. So in the background it does conversion checks. :ermm:

    I know I'm being a bit pedantic here but you didn't "get hit" by ISNUMERIC... you used ISNUMERIC incorrectly. 😉 I'll admit that the MS documentation isn't in-your-face clear about what it doesn't do (it was never meant to be an IsAllDigits function), but it does state exactly what it does do.

    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.
