    Simple and nice article,

    some time back i was working on validating a column in the database and i came across this issue and we had this function to validate.

    This poster brings up a good point: "-" and ".".

    If you're looking for valid numbers, I agree. If you're looking for an "IsAllDigits" function, you wouldn't want to include those two characters.

    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.
