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。

复制代码 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
