    I'm doing my first adjacency list to nested sets conversion and building out a rather complex hierarchy table for a new project (something I've been anxious to do since I saw your presentation). I've re-read this article a couple times this week. It's all going very well. Thanks again for this fantastic article and technique Jeff!

    -- The ISNULLs make NOT NULL columns

    I just caught that and learned something new tonight. How very cool.

    Really cool feedback, Alan. Thank you so much! If you need help on something there, you know where I can be found. 🙂 I'll be really interested to hear how your project panned out.

    Heh... and don'cha just love some of the comments I put in my code. :w00t:

    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.
