ALTER PROCEDURE [dbo].[mysp]
AS
declare @.returnValue int
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
-- Insert statements for procedure here
select COUNT(DISTINCT numberofitems) from items
END
set @.returnValue = ?
return @.returnValueYou need to use an output parameter. Have a look at these:

>|||This is an example I just posted to my book's "Ask Answer" support site. It
calls a SP that returns the Identity value as a Return value. No, you don't
need an output parameter for this--the Return will work fine if you can pass
back an Int.
