    Two possible answers, both will work:

    TOP

    ROW_NUMBER

    TOP

    ROW_NUMBER

    Simple MAX would do it...

    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.

    Simple isn't nearly as much fun. Small data set, ROW_NUMBER may perform better.
