This is related to the following post:
The function that retrieves the item counts for each folder (category) is:
ALTER FUNCTION [dbo].[GetFolderReceiptCount]
(
-- Add the parameters for the function here
@FolderID bigint
)
RETURNS int
AS
BEGIN
DECLARE @Return int
SET @Return = 0
SELECT
--H.ReceiptFolderID,
@Return = COUNT(H.ReceiptFolderID)
FROM
tbl_ReceiptFolderLnk H
JOIN tbl_Receipt D ON H.ReceiptID = D.ReceiptID
WHERE ReceiptFolderID=@FolderID
GROUP BY
H.ReceiptFolderID
-- Return the result of the function
RETURN @Return
END
How can this be altered to return counts for each parent?
