    Can I ask why you don't want a loop? Recursion via a common table expression (CTE) can be your friend in this case.

    DECLARE @fromYear DATETIME, @toYear DATETIME

    SELECT @fromYear='1913-01-01', @toYear='1998-01-01'

    WITH YearSequence (Year) as

    (

    SELECT @fromYear AS Year

    UNION ALL

    SELECT DATEADD(YEAR, 1, Year)

    FROM YearSequence

    WHERE Year < @toyear

    )

    SELECT Year FROM YearSequence ORDER BY 1 DESC

    Because of the extremely low rowcount, you can't actually see the insidious problem with CTE's that count. Please see the following article...

    Also, your code didn't actually run right the first time I tried to run it because of missing semi-colons. You might also want to get out of the habit of using ORDER BY on a column ordinal because that method has been deprecated.

    As for why you might want to avoid a loop, do you have a good reason for why you'd want to intentionally write slower code when faster code is easily available and usually easier to write?

    Thanks for sharing the article, Jeff. I learn something new everyday and this tops the list for past 24 hours.

    born2achieve, don't use my example. Take a few minutes to read the article Jeff wrote, its extremely evident that there are better methods available such as a tally table.
