    I would honestly expect (but not certain here) that a scalar UDF that just puts it's output into a variable would be more efficient than iTVF that returns one row one column table simply due to less overhead related to the output format (variable vs table).

    Then you've got to read the following.

    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.
