    Hi from a result like this

    NumCodeStart DateEnd Date

    204-201ABCDF2004-04-04NULL

    204-203ABCDF2004-07-18NULL

    204-205QWERT,ASDFG2005-12-05NULL

    204-206YUIOP,GHJKL2006-05-11NULL

    I wish to get this :

    NumCodeStart DateEnd Date

    204-201ABCDF2004-04-04NULL

    204-203ABCDF2004-07-18NULL

    204-205QWERT2005-12-05NULL

    204-205ASDFG2005-12-05NULL

    204-206YUIOP2006-05-11NULL

    204-206 GHJKL2006-05-11NULL

    The column that sometimes has coma seperated values are then split to creat another record with same Num, Start Date and End Date.

    You need to utilize the DelimitedSplit8K function to split the delimited list apart.

    You would use it like so:

    SELECT Num, Item AS Code, [Start Date], [End Date]

    FROM #TEST t

    CROSS APPLY DelimitedSplit8K(t.Code, ',') ds

    ORDER BY t.Num, ds.ItemNumber

    Here is the latest version of the Delimited Split Function

    Are you sure? When I run this code:

    DECLARE @test-2 TABLE (Num CHAR(7), Code VARCHAR(50), [Start Date] DATETIME, [End Date] DATETIME);

    INSERT INTO @test-2

    SELECT '204-201','ABCDF', '2004-04-04', NULL UNION ALL

    SELECT '204-203','ABCDF','2004-07-18', NULL UNION ALL

    SELECT '204-205','QWERT,ASDFG','2005-12-05', NULL UNION ALL

    SELECT '204-206','YUIOP,GHJKL','2006-05-11', NULL ;

    SELECT Num, Item AS Code, [Start Date], [End Date]

    FROM @test-2 t

    CROSS APPLY DelimitedSplit8K(t.Code, ',') ds

    ORDER BY t.Num, ds.ItemNumber

    I get exactly the desired results:

    Num Code Start Date End Date

    ------- ----- ----------------------- -----------------------

    204-201 ABCDF 2004-04-04 00:00:00.000 NULL

    204-203 ABCDF 2004-07-18 00:00:00.000 NULL

    204-205 QWERT 2005-12-05 00:00:00.000 NULL

    204-205 ASDFG 2005-12-05 00:00:00.000 NULL

    204-206 YUIOP 2006-05-11 00:00:00.000 NULL

    204-206 GHJKL 2006-05-11 00:00:00.000 NULL

    Could you post the code that didn't do the trick? Thanks.

    I would also very much like to see the code that didn't work. I've been using Wayne's technique and Jeff's Delimited8KSplit for a while now and those techniques have always worked.

    Hi all,

    I apologize, the solution suggested by Wayne is working fine.

    I made a mistake with that part of the solution (t.Code, ',') ds.

    Thanks for the feedback on this... it would have been quite a shock to many people if this routine wasn't working correctly!
