　　今天看到一篇文章介绍2012中的分页，就想测试一下新的分页方法比原先的有多少性能的提升，下面是我的测试过程（2012的分页语法这里不在做多的说明,MSDN上一搜就有）：

　　首先我们来构造测试数据：

--建表
CREATE TABLE [dbo].[MyCustomer](
    [id] [int] PRIMARY 
KEY,
    [CustomerNumber] [varchar](25),
    [CustomerName] [varchar](25),
    [CustomerCity] [varchar](25)
)
 
 
--生成100W测试数据
DBCC DROPCLEANBUFFERS  
DBCC FREEPROCCACHE  
   
SET STATISTICS IO ON;  
SET STATISTICS TIME ON;  
 
 
;WITH 
mycte AS
(
    SELECT 
id=1,CustomerNumber=CAST(‘0000‘ 
AS VARCHAR(25)),
    CustomerNamer=CAST(‘AAAA‘ 
AS VARCHAR(25)),
    CustomerCity=CAST(‘CCCC‘ 
AS VARCHAR(25))
    UNION 
ALL
    SELECT 
id=id+1,
    CustomerNamer=CAST(CHECKSUM(NEWID()) AS 
VARCHAR(25)),
    CustomerNamer=CAST(‘Name‘+CHAR(65+id%26) AS 
VARCHAR(25)),
    CustomerCity=CAST(CHAR(65+id%26) AS 
VARCHAR(25)) FROM 
mycte WHERE 
id<1000000
) 
INSERT 
INTO MyCustomer SELECT 
* FROM mycte
OPTION(MAXRECURSION 0)
 
SET STATISTICS IO OFF ;  
SET STATISTICS TIME OFF;
