I have a table

CREATE TABLE #IMaster (ID INT, ITEM1 VARCHAR(100))
GO INSERT #IMaster SELECT 1,'pencil' UNION SELECT 2,'pen/pencil' UNION SELECT 3,'ink' UNION SELECT 4,'pen/pencil/ink/'

I need to create a view like this

ID id1 ITEM1
1 1 pencil 2 1 pen 2 2 pencil 3 1 ink 4 1 pen 4 2 pencil
4 3 ink

We are still working on sql 2000.

Thanks in advance

check SSC for a split (table valued) function .

e.g.



 /*

  *  Split a delimited string using a table valued function with XML

 */

-- table-valued function

CREATE     FUNCTION dbo.fn_DBA_Split2(@Data varchar(4000),

	@Delimiter varchar(10) = ',')

RETURNS @tblSplit TABLE

	(ItemId int IDENTITY(1, 1) NOT NULL PRIMARY KEY,

	Item varchar(4000) NULL)

AS

BEGIN

-- select e.*

-- from pubs..employee E

-- inner join master.dbo.fn_DBA_Split2('ikke,jij,hij,zij,Karin',',') U

-- on E.fname = U.item

	DECLARE @x XML

	SET @x = '<i>' + REPLACE( @Data, @Delimiter, '</i><i>') + '</i>'

	INSERT INTO @tblSplit (Item)

		SELECT x.i.value('.', 'VARCHAR(4000)')

		FROM @x.nodes('//i') x(i)

	RETURN

END

go

select e.*

from pubs..employee E

inner join master.dbo.fn_DBA_Split2('ikke,jij,hij,zij,Karin',',') U

on E.fname = U.item

Oh... be careful, Johan... XML splits are relatively slow compared to many other methods.

Take a look at the following article, Jay.

Oh... be careful, Johan... XML splits are relatively slow compared to many other methods.

Indeed, I copy/pasted the wrong example code out of one of my test scripts.

That's why I hinted to search ssc for split functions.

OP would have come to your marvellous article without a doubt 😉

Should have pointed to that in the first place 😎

Plus the OP indicated he was still on SQL 2000 (despite posting in the SQL 2005 forums). So XML is out of the picture anyway.
