How about this?

CREATE FUNCTION dbo.SplitString ( @string varchar(4000))

RETURNS @Result TABLE(SpiltedString VARCHAR(100))

AS

BEGIN

DECLARE @xml XML

SELECT @xml = CAST('<VALUE>'+ REPLACE(@string,',','</VALUE><VALUE>')+ '</VALUE>' AS XML)

INSERT INTO @Result

SELECT t.value('.', 'VARCHAR(100)') AS inVal

FROM @xml.nodes('/VALUE') AS x(t)

RETURN

END

GO

Create table #MYTEMP

(Id int ,

value nvarchar(100),

name varchar(50))

insert into #MYTEMP VALUES(1,'B,C,D','XYZ')

SELECT ID, fnResult.SpiltedString, name

FROM #MYTEMP

CROSS APPLY DBO.SplitString(value) as fnResult

DROP FUNCTION dbo.SplitString

DROP TABLE #MYTEMP

Ignore the post above this one of yours. I'm pretty sure it wasn't meant for you.

As Sean said earlier. please start your own thread to ask questions instead of using this one. It is just going to confuse you.

Start fresh.

Please see the article in my signature about splitting strings. It will show you a better alternative than this type of xml splitter for splitting strings. It includes code almost exactly the same as this splitter and demonstrates a way that is WAY faster.

Heh... you're on it now. 😉

--Jeff Moden

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.
