当表2的列值更改时更新表1 **无触发器**

Question

当表2中列的值更改时，我正在尝试更新表1中的列。我试图避免使用SQL Server触发器，因为启用触发器后，我在应用程序中遇到了很多问题。另外，它必须是表2的即时更新。非常感谢您的帮助。

谢谢

编辑。我添加了我使用的触发器。但这效率很低并且引起了问题

    CREATE TRIGGER trg_Update
    ON [dbo].[tblTable1]
    AFTER UPDATE
AS

DECLARE
    @v_orderId int,
    @v_proId int,
    @v_statusId int

BEGIN
    SELECT @v_orderId = OrderID
    FROM inserted

    SELECT @v_proId = ProdID
    FROM tblTable1
    WHERE OrderID = @v_orderId

    SELECT @v_statusId = v.VisitStatusID
    FROM tblTable1 v
    INNER JOIN
    (
        SELECT MAX(DueDate) AS MaxDueDate, ProdID
        FROM tblTable1
        GROUP BY ProdID
    ) t2 ON v.ProdID = t2.ProdID
    AND v.DueDate = t2.MaxDueDate
    WHERE v.ProdID = @v_proId

    IF @v_statusId IN (5, 25)
        BEGIN
            UPDATE tblTable2 SET Buyer= 'CP1' WHERE ProdID = @v_proId
        END
    ELSE
        BEGIN
            UPDATE tblTable2 SET Buyer= 'CP2' WHERE ProdID = @v_proId
        END
END
