Hi
I have the following parts data in a table in SQL Server
OEM_PartNumber      Device_List
001R00588                            | WCP7132 | WorkCentre 7132 | WCP7132 | WorkCentre 7132 |
001R00593                            | WorkCentre 7232 | WorkCentre 7242 | WorkCentre 7232 |

I have a split string function and if I pass in the string from the Device List field above
select * from dbo.fn_SplitString('|', '| WCP7132 | WorkCentre 7132 | WCP7132 | WorkCentre 7132')
I get the records returned as follows

1       WCP7132
2       Xerox WorkCentre 7132
3       Xerox WCP7132
4       WorkCentre 7132

i.e a record for every string delimited by the |

using this function(maybe I need to modify the function) or some other trick(maybe CTE) I want to achive the the data in the following format for every record in the parts table

001R00588        WCP7132
001R00588        WorkCentre 7132
001R00588       WCP7132
001R00588       WorkCentre 7132
001R00593        WorkCentre  7232
001R00593        WorkCentre 7232
001R00593        WorkCentre 7232P
001R00593        WorkCentre 7242
001R00593        WorkCentre Pro 7232
001R00593       WorkCentre 7232

so I get a record for each string delimited by the pipe in the parts table, for every record in the parts table and the relevant part number beside it

This is the code for the split string function
ALTER FUNCTION [dbo].[fn_SplitString](@sep char(1), @s varchar(8000))
RETURNS TABLE
AS
RETURN
(
      WITH Pieces(pn, start, stop)
      AS (      
      SELECT 1, 1, CHARINDEX(@sep, @s)      
      UNION ALL      
      SELECT pn + 1, stop + 1, CHARINDEX(@sep, @s, stop + 1)      
      FROM Pieces      
      WHERE stop > 0    
      )    
      SELECT pn,      
      SUBSTRING(@s, start, CASE WHEN stop > 0 THEN stop-start ELSE 8000 END) AS s    
      FROM Pieces
)
