  here iam using a parameter

  declare @Questions varchar(MAX)='1-2|32,42-41|44'

  this should be splited in to three column

  declare @Questions varchar(MAX)='1-32,42-41'

  ;WITH CTE1 AS(

  SELECT id, LEFT(val, CHARINDEX('-', val)-1) AS QuestionId, SUBSTRING(val, CHARINDEX('-', val)+1, 100) AS [IndexNumber]

  FROM [dbo].[FN_SplitData](@Questions,',')

  )

  select QuestionId,[IndexNumber] from CTE1

  in which i receviwed output like this

  QuestionId IndexNumber

  1 32

  42 41

  using this split function

  ALTER FUNCTION [dbo].[FN_SplitData](

  @delimited NVARCHAR(MAX),

  @delimiter NVARCHAR(100)

  ) RETURNS @t TABLE (id INT IDENTITY(1,1), val NVARCHAR(MAX))

  AS

  BEGIN

  DECLARE @xml XML

  SET @xml = N'<t>' + REPLACE(@delimited,@delimiter,'</t><t>') + '</t>'

  INSERT INTO @t(val)

  SELECT r.value('.','varchar(MAX)') as item

  FROM @xml.nodes('/t') as records(r)

  RETURN

  END

  i just tried like this

  declare @Questions varchar(MAX)='1-32|26,42-41|32'

  ;WITH CTE1 AS(

  SELECT id, LEFT(val, CHARINDEX('-', val)-1) AS QuestionId, SUBSTRING(val, CHARINDEX('-', val)+1, 100) AS [IndexNumber]

  , SUBSTRING(val, CHARINDEX('|', val)+1, 100) AS Numbers

  FROM [dbo].[FN_SplitData](@Questions,',')

  )

  select QuestionId,[IndexNumber],Numbers from CTE1

  which provieded output like this

  QuestionId IndexNumber Numbers

  1 32|2626

  42 41|3232

  but iam trying output like this

  QuestionId IndexNumberNumbers

  1 32 26

  SELECT LEFT(val, CHARINDEX('-', val)-1) AS QuestionId

  , substring(val,(CHARINDEX('-', val)+1),(CHARINDEX('|', substring(val,(CHARINDEX('-', val)+1),len(val)))-1)) AS [IndexNumber]

  , SUBSTRING(val, CHARINDEX('|', val)+1, 100) AS Numbers

  from FN_SplitData(@Questions,',')

  Not very useful unless one has a copy of "FN_SplitData". Please post it. Thanks.

  Edit: Apologies and never mind... I see it further above in this thread.

  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.
