    dwain.c (10/7/2012)

    I don't think this has the same issue that Jeff is reporting about Mark's but it's just another option:

    Gosh. Good bit of code, Dwain, but it also has a full cross join in it according to the actual execution plan. Again, I don't know if these things will "convert" to something else if the row count gets bigger or not. Guess I'll have to give it a try.

    I'm really interested in this problem because I normally use the Quirky Update for "data smears" like this and I'd love to see a different method that didn't end up with a cross join in 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.

    Change is inevitable... Change for the better is not.
