SQLSERVER触发器inserted和deleted表。在触发器语句中用两个特殊的表一个是deleted表和inserted。它们是通过触发器操作自动创建驻留在内存中的临时表。

Deleted表用于存储 DELETE和 UPDATE语句所影响的行的复本。在执行DELETE或 UPDATE语句时，行从触发器表中删除，并传输到 deleted表中。Deleted表和触发器表通常没有相同的行。

Inserted 表用于存储 INSERT 和 UPDATE 语句所影响的行的副本。在一个插入或更新事务处理中，新建行被同时添加到 inserted 表和触发器表中。Inserted 表中的行是触发器表中新行的副本。

如果我们想要获取我们刚插入或删除数据库中的内容，就可以从这两张表中获取

下面附上我写的例子，就是当向人工录入数据表中插入数据时，获取插入的数据值，并操作其他表格

USE [DB_GreenPower]
GO /****** Object: Trigger [dbo].[deleteData] Script Date: 2016/12/17 22:53:06 ******/
SET ANSI_NULLS ON
GO SET QUOTED_IDENTIFIER ON

AFTER INSERT
AS
BEGIN
--获取插入时间的第一天对应的时间
declare @time datetime,@RecTime datetime

set @time=CONVERT(datetime,DATENAME(year, @RecTime)+'-'+DATENAME(MONTH, @RecTime)+'-1')
--添加完人工录入数据以后，删除之前创建的人工录入数据
