SQL Server 2008 VALUES
SQL Server 2008中新增功能:可以使用单个Insert命令插入多行。
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)
除了可以一次性插入多行,values还有更巧妙的用法,不使用永久表或临时表而表示一个结果集,而且不需要函数或表变量。看下面的例子:
--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
