AS
BEGIN
SET NOCOUNT ON;
insert into [dnt_userfields](uid)

复制代码 代码如下:

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

CREATE TRIGGER [dnt_users_del]

AS
BEGIN

SET NOCOUNT ON;
delete [dnt_userfields] from deleted where [dnt_userfields].uid=deleted.uid

END
GO

复制代码 代码如下:

GO

ALTER TRIGGER [dnt_users_up]
