    Actually, just had cause to revisit this particular thread...

    ... and it just dawned on me that tests in the article are not measuring the performance of each method... the tests are measuring how well each method runs a loop which has nothing to do with transferring data to a file. If you want a real test, build a table with desired number of rows (100k for example) and then simply select from that table using each method. The results will be drastically different.

    Here's how to build a 100k row table of numbers in an eye-blink...

    SELECT TOP 100000

    IDENTITY(INT,1,1) AS N

    INTO dbo.Numbers

    FROM Master.dbo.SysColumns sc1,

    Master.dbo.SysColumns sc2

    And, yeah... where is the test for BCP?

    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.
