    You mean just as a separate post or here or did you have something else in mind, Barry?

    Right, a separate post, with a data set (million rows, of course) and a formal statement of the challenge ("fastest execution time to produce result set like this ...".

    I actually have a fair start on the data set...

    Got it. I'll see what i can do. Thanks, Barry.

    Wow... talking about a forgotten promise... my apologies, Barry.

    That, notwithstanding, please see the following article which also has a million row "clean" hierarchy generator.

    This next one is part of the same series (2 articles in the series) and provides an alternate to all of the currently known hierarchical structures.

    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.
