    Yes/NoA logical field can be displayed as Yes/No, True/False, or On/Off. In code, use the constants True and False (equivalent to -1 and 0). Note: Null values are not allowed in Yes/No fields

    Heh... Six years old or not, there's no datatype for Yes/No in T-SQL. The closest you can come is the BIT datatype, which takes 1s, 0s, and NULL and has some annoyances like not being able to SUM() a BIT column directly.

    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.
