inserted,deleted是在触发器中使用的两个临时表,当执行insert操作时,在inserted中存储着当前插入的记录,在执行delete操作时,在deleted中存储着当前删除的记录,当执行update时,在inserted中存储着修改后的记录,在deleted中存储着修改前的记录。

set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
go
ALTER TRIGGER [dnt_user_add]

AS
BEGIN
SET NOCOUNT ON;
insert into [dnt_userfields](uid)
select uid from inserted
END
