Hi all,

I have two tables. One is users and others is wholesalers. I have created a stored procedure which takes a comma seperated list of wholesaleid and deletes records in wholesale. user table has userid as primary key which is also a foreign key in wholesaler table. I want to update user record when its wholesaler record is deleted.
wholesale and user table has one to one relation with user table as primary table.

Following is my sp:

ALTER PROCEDURE [dbo].[Delete_WholeSalers] (
@WholesalerIDs VARCHAR(MAX)
)

AS

SET NOCOUNT ON

delete from [WholeSalers]
WHERE
CAST(WholesalerID AS VARCHAR(50)) in(select * from [fn_SplitToList]
(@WholesalerIDs))

--update users table based on userid in wholesale table

Please help me on this.

Regards,
Asif Hameed

Something like this

ALTER PROCEDURE dbo.Delete_WholeSalers
(
	@WholesalerIDs VARCHAR(MAX)
)
AS

SET NOCOUNT ON

DECLARE	@IDs TABLE
	(
		ID INT
	)

DELETE
OUTPUT	deleted.WholesalerID
INTO	@IDs
FROM	[WholeSalers]
WHERE	CAST(WholesalerID AS VARCHAR(50)) in (SELECT * FROM fn_SplitToList(@WholesalerIDs))

UPDATE		w
SET		w.SomeCol = 0
FROM		Customers AS w
INNER JOIN	@IDs AS i ON i.ID = c.WholesalerID
