  • RE: Variables, Nulls and Coalesce

    Okay, nope, it is called twice. Once for each column. Changed the Tally version to generate 100,000 records. Guess what, Date1 was the same for...

    Yes. I think that typical system clock resolution is 0.060 seconds. In spite of CPU speed, the clock doesn't register every millisecond.

    I really missed something else, but learned something as well just now.

    1) Multiple calls to getdate() in the same query will return the same value.

    2) Multiple calls to...

  • RE: T-SQL

    As it happens, SQL Server does not recognize GetDate() and GetUtcDate() as being equal.

    Take a look at this:

    IF GETDATE() = GETUTCDATE()

    SELECT 'TRUE'

    ELSE

    How very elegant, and cool. It's so well explained that I know I'll remember it the next time I have to do some cleanup.

    Regarding my temp table without ORDER BY observation:

    Jeff,

    Terrific article. I haven't used Quirky Update for a few years, and that's a good thing because I didn't know all of the rules.
