SQL Server 2008中SQL：Values新用途

SQL Server 2008中新增功能：可以使用单个Insert命令插入多行。

[ruby]
view plaincopyprint?

Create table Demo_Values
(PKID int not null identity(1,1) primary key

,DName Nvarchar(20) null
,DCode NVarchar(30) null
,DDate datetime null
)
go
--this SQL is only for SQL Server 2008

Insert into Demo_Values
(DName,DCode,DDate)
values
('DemoA','AAA',GETDATE()),

('DemoB','BBB',GETDATE()),

('DemoC','CCC',GETDATE()),

('DemoD','DDD',GETDATE()),

('DemoE','EEE',GETDATE())

--(5 row(s) affected)

[ruby]
view plaincopyprint?

--this SQL is only for SQL Server 2008

select DName,DCode,DDate
from
(values
('DemoA','AAA',GETDATE()),

('DemoB','BBB',GETDATE()),

('DemoC','CCC',GETDATE()),

('DemoD','DDD',GETDATE()),

('DemoE','EEE',GETDATE())

)
Demo_Values (DName,DCode,DDate)
--(5 row(s) affected)
/*
DName DCode DDate
DemoA AAA 2010-10-12 20:37:45.500
DemoB BBB 2010-10-12 20:37:45.500
DemoC CCC 2010-10-12 20:37:45.500
DemoD DDD 2010-10-12 20:37:45.500
DemoE EEE 2010-10-12 20:37:45.500
*/

--this SQL is only for SQL Server 2008
select DName,DCode,DDate
from
(values
('DemoA','AAA',GETDATE()),
('DemoB','BBB',GETDATE()),
('DemoC','CCC',GETDATE()),
('DemoD','DDD',GETDATE()),
('DemoE','EEE',GETDATE())
)
Demo_Values (DName,DCode,DDate)
--(5 row(s) affected)
/*
DName    DCode    DDate
DemoA    AAA    2010-10-12 20:37:45.500
DemoB    BBB    2010-10-12 20:37:45.500
DemoC    CCC    2010-10-12 20:37:45.500
DemoD    DDD    2010-10-12 20:37:45.500
DemoE    EEE    2010-10-12 20:37:45.500
*/

注意该语句的最后一行定义了“源”名称和列名,其中列名用于select语句。
