最近项目中使用了SCOPE_IDENTITY()来获取新增数据的自动递增ID号. 在运行过程中会不时的发生无法通过SCOPE_IDENTITY()来获取ID号的情况. 尝试着测试又发现不了问题. 今天在官网发现了OUTPUT可以代替使用. 先尝试一个例子: Create Table dbo.test( nid int Id

最近项目中使用了SCOPE_IDENTITY()来获取新增数据的自动递增ID号.

在运行过程中会不时的发生无法通过SCOPE_IDENTITY()来获取ID号的情况.

尝试着测试又发现不了问题.

今天在官网发现了OUTPUT可以代替使用.

先尝试一个例子:

Create Table dbo.test(

nid int Identity(1,1),

n varchar(20)

)

declare @tmptest Table (

nid int,

n varchar(20)

)

---新增

insert into dbo.test(n)

OUTPUT INSERTED.nid,INSERTED.n into @tmptest

values('你好')

select * from @tmptest

select * from dbo.test

有点触发器的感觉...

对更新和删除操作同理,详细介绍地址为:
