I think it's not possible for you to delete a row on the 3rd table. You don't have @given_ID there.

Maybe, you could use joins?

Solution 2

The best method to get this effect is to specify FOREIGN KEYS between the table with an ON DELETE trigger. (On Delete=CASCADE).

So just delete the Given_Id(main table) and it will automatically delete the related one.

Hope it helps :)

SQL

you can use Trigger


create trigger [dbo].[tri_Name] on tbl_Ag_Master
for delete
as
declare @Given_Id bigint;
declare @Assignment_Id bigint

select @Assignment_Id=d.Assignment_Id from deleted d;
select @Given_Id =d.Given_Id  from deleted d;

delete  from tbl_Ag_Child where Given_id=@Given_Id

delete from tbl_Bach_Ag where Assignment_Id_id=@Assignment_Id
