Change letterCase to 'small', do not use capital letters. it means "Shouting".

Hi,

You could define Foreign Key constraints for the other tables that reference
the master table's primary key with ON DELETE CASCADE. This would cause the
related rows in those tables to be deleted. See the discussion thread below,

you can do this by stored procedure as

SQL

CREATE PROCEDURE proc_delete_item
@ItemCode int,

AS
SET NOCOUNT off
DECLARE  @LocalError int

BEGIN TRANSACTION

DELETE FROM ITEMMAST where ItemCode=@ItemCode
DELETE FROM SAUDAMAST where ItemCode=@ItemCode
DELETE FROM PITBROK where ItemCode=@ItemCode

SELECT @LocalError = @@Error
IF NOT @LocalError = 0
    BEGIN
    ROLLBACK TRANSACTION
    SELECT  Error = @LocalError
        
    END
ELSE
    BEGIN
    COMMIT TRAN
   
    SELECT  Error = 0 
    END
