sql 分页

1create database data_Test  --创建数据库data_Test 

 2GO 

 3use data_Test 

 4GO 

 5create table tb_TestTable   --创建表 

 6( 
   id int identity(1,1) primary key, 
   userName nvarchar(20) not null, 
   userPWD nvarchar(20) not null, 
   userEmail nvarchar(40) null 

11) 

12GO

1--插入数据 

 2set identity_insert tb_TestTable on 

 3declare @count int 

 4set @count=1 

 5while @count<=2000000 

 6begin  
   insert into tb_TestTable(id,userName,userPWD,userEmail) values(@count,‘admin‘,‘admin888‘,‘lli0077@yahoo.com.cn‘) 
   set @count=@count+1 

 9end 

10set identity_insert tb_TestTable off

利用select top 和select not in进行分页，具体代码如下：

1create procedure proc_paged_with_notin  --利用select top and select not in 

 2( 
   @pageIndex int,  --页索引 
   @pageSize int    --每页记录数 

 5) 

 6as 

 7begin 
   set nocount on; 
   declare @timediff datetime --耗时 
   declare @sql nvarchar(500) 
   select @timediff=Getdate() 
   set @sql=‘select top ‘+str(@pageSize)+‘ * from tb_TestTable where(ID not in(select top ‘+str(@pageSize*@pageIndex)+‘ id from tb_TestTable order by ID ASC)) order by ID‘ 
   execute(@sql)  --因select top后不支技直接接参数，所以写成了字符串@sql 
   select datediff(ms,@timediff,GetDate()) as 耗时 
   set nocount off; 

16end

create procedure proc_paged_with_selectMax  --利用select top and select max(列) 
 2( 
 3    @pageIndex int,  --页索引 
 4    @pageSize int    --页记录数 
 5) 
 6as 
 7begin 
 8set nocount on; 
 9    declare @timediff datetime 
10    declare @sql nvarchar(500) 
11    select @timediff=Getdate() 
12    set @sql=‘select top ‘+str(@pageSize)+‘ * From tb_TestTable where(ID>(select max(id) From (select top ‘+str(@pageSize*@pageIndex)+‘ id From tb_TestTable order by ID) as TempTable)) order by ID‘ 
13    execute(@sql) 
14    select datediff(ms,@timediff,GetDate()) as 耗时 
15set nocount off; 
16end

1create procedure proc_paged_with_Rownumber  --利用SQL 2005中的Row_number() 

 2( 
   @pageIndex int, 
   @pageSize int 

 5) 

 6as 
   declare @timediff datetime 

 8begin 

 9set nocount on; 
   select @timediff=getdate() 
   select * from (select *,Row_number() over(order by ID asc) as IDRank from tb_testTable) as IDWithRowNumber where IDRank>@pageSize*@pageIndex and IDRank<@pageSize*(@pageIndex+1) 
   select datediff(ms,@timediff,getdate()) as 耗时 

13set nocount off;
