    ...and anything that you can do in a cursor you can be accomplished in a loop and/or temp table.

    A temp table and While Loop is just as bad as a cursor and a nicely written "FireHose" cursor is just as easy to use. The key is to avoid the loop. Replacing a cursor with a Temp Table and While Loop is a futile effort and mostly a waste of time and effort.

    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.
