I have declare a temporary table @OrgTable and I'm populating it with a single column of strings which represent organisation codes.
Prior to populating @OrgTable the codes are part of a continuous string which are delimited by a '|'.
I have written a function SplitString to do just that and the individual codes are then inserted into the table.
Finally I'm calling a second function, NBOCAP, into which I pass a start date, and end date and each organisation code from @OrgTable so I need to modify my script so it iterates through each organisation code. What form should my script take please? It needs to be backwards compatible with SQL2000.



DECLARE @OrgTable TABLE
	(
		elem varchar(1000)
	)

INSERT INTO @OrgTable
SELECT * FROM SplitString(@OrgCodeString, '|')

SELECT * FROM NBOCAP(@StartDate,@EndDate,organisation code)

use the APPLY function

SELECT *
FROM   @OrgTable
       CROSS APPLY NBOCAP(@StartDate,@EndDate,elem)


EDIT : just saw the backward compatibly requirement. You can't use APPLY in 2000. For 2000, best is to everything in a function or to use stored procedure
