Tsql stored procedure - passing multiple variables

Question

Hi,
I have a dropdown field on a form that allows for multiple
selects. When I process the form, I currently use CF to dynamically
generate the sql WHERE clause creating as many AND statements as
needed.
I'm migrating to MS SQL 2005 and Stored Procedures on the db.
I'm trying to create a stored procedure that effectively uses tsql
to do what CF was doing previously (creating the WHERE clause).
In the code below, I am passing a char(22) variable called
Channel. The code below was my initial attempt at trying to create
the WHERE clause. Most of the code is focused on extracting out the
individual "Channel" entities. Any thoughts on how to pull this
together would be GREATLY appreciated!
I'm need help on the SELECT side, ultimately I'm selecting
"regions", from "Syndicated", the WHERE is based on the "Channels"
passed.
Thanks,
cfwild

Hi,
This was quite the adventure trying to figure this out. I
learned quite a bit about tsql. Here is the final procedure:
CREATE PROCEDURE dbo.uspSelectSyndicatedRegion
@TablePrefix char(7),
@Category varchar(100),
@Channel varchar(2000)
AS
BEGIN
SELECT DISTINCT S.Region
FROM Syndicated S
JOIN iter_charlist_to_tbl(@Channel, DEFAULT) M
ON S.Channel = M.str
UNION
SELECT ''
ORDER BY S.Region
END
