• Now this is interesting. Watch what happens when you try to find out how many of those random integers are randomly repeated:

    SELECT Number, COUNT(*)

    FROM (SELECT ABS(CHECKSUM(NEWID()))%(500-300+1)+300 AS Number

    FROM dbo.Numbers

    WHERE number <= 200

    ) d

    GROUP BY Number

    ORDER BY Number

    โ€œWrite the query the simplest way. If through testing it becomes clear that the performance is inadequate, consider alternative query forms.โ€ - Gail Shaw
