    Jeff - I believe you're looking for the October 1985 article series in Computerworld, by Codd, entitled:

    Does your DBMS Play by the rules

    From Codd's own description it's the first time he went into all 12 rules in a single article. The first article is the base definition of the 12 (and rule 0), with a follow-on article to describe the details and corrolary rules.

    As far as I know, it's still under copyright, so I can't post copies.

    Thanks Matt... I'll check it out.

    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.
