实现代码如下：
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
删除：
实现代码如下：
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：
实现代码如下：
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
