    When I was watching Merge slide show. I have observed
    You can insert records with the following statement
    INSERT INTO Production.UnitMeasure VALUES ((N'F2', N'Square Feet', GETDATE()),(N'Y2', N'Square Yards', GETDATE()));
    Any internal details which one performs better writign multiple inserts OR writing insert statement like above?
    another FUNNY stuff
    fter installing Katmai BOL C:program FilesMicrosoft SQL Server100License TermsLicense_BOL_en.txt
    If you open this file it shows

    Have you checked the execution plan for those 2 statements?
    It also depends upon the volume of the data including the indexes.

    I do not have 2008 on my machine. I can't test it. IF you guys find something intersting please let me know.

    Looks like you can have a series of VALUES clauses, separated with a comma.
    Not really new functionality - we can use SELECT with a values list, and we can use UNION:
    INSERT INTO Production.UnitMeasure
    SELECT N'F2', N'Square Feet', GETDATE()
    UNION SELECT N'Y2', N'Square Yards', GETDATE()

    I shouldn't think there would be much difference between the 2 different ways of constructing the insert statement.

    Agree - just pointing out that it's probably a new variation on existing syntax in Katmai, which can already be implemented with other existing syntax in current SQL versions.

    What I have suggested is performance and single insert statement (reduction in network traffic).
    I was also looking for such a notes within BOL, not sure it will be mentioned in SQL2008 BOL.
