    Jeff, there are zillions of lines of app code that have queries joining on and referencing the UUID.

    So why are you talking about building a function? The Key Lookups just aren't going to be that bad. Certainly no worse than you maing a function.

    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.
