觸發器里沒有updated ，只有inserted 和deleted兩個臨時表。
inserted,deleted是在觸發器中使用的兩個臨時表，當執行insert操作時，在inserted中存儲著當前插入的記錄，在執行delete操作時，在deleted中存儲著當前刪除的記錄,當執行update時，在inserted中存儲著修改后的記錄，在deleted中存儲著修改前的記錄。
代碼如下:
set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
go
ALTER TRIGGER [dnt_user_add]
ON [dbo].[dnt_users]
AFTER INSERT
AS
BEGIN
SET NOCOUNT ON;
insert into [dnt_userfields](uid)
select uid from inserted
END
刪除：
代碼如下:
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TRIGGER [dnt_users_del]
ON [dnt_users]
AFTER DELETE
AS
BEGIN
SET NOCOUNT ON;
delete [dnt_userfields] from deleted where [dnt_userfields].uid=deleted.uid
END
GO
修改：
代碼如下:
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER TRIGGER [dnt_users_up]
ON [dnt_users]
AFTER UPDATE
AS
BEGIN
SET NOCOUNT ON;
UPDATE [dnt_userfields] Set icq = inserted.uid from inserted where [dnt_userfields].uid = inserted.uid
END
GO
