SQL Server分页的存储过程写法以及性能比较

 ------创建数据库data_Test -----
create database data_Test 
 GO 
use data_Test 
GO 
create table tb_TestTable   --创建表 
( 
    id int identity(1,1) primary key, 
    userName nvarchar(20) not null, 
    userPWD nvarchar(20) not null, 
    userEmail nvarchar(40) null 
) 
GO

------插入数据------ 
 set identity_insert tb_TestTable on 
 declare @count int 
 set @count=1 
 while @count<=2000000 
 begin 
    insert into tb_TestTable(id,userName,userPWD,userEmail) values(@count,'admin','admin888','lli0077@yahoo.com.cn') 
     set @count=@count+1 
 end 
set identity_insert tb_TestTable off

---1、利用select top 和select not in进行分页,具体代码如下
create procedure proc_paged_with_notin  --利用select top and select not in 
 ( 
     @pageIndex int,  --页索引 
     @pageSize int    --每页记录数 
 ) 
 as 
 begin 
     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; 
end


---2、利用select top 和 select max(列键)---

 create procedure proc_paged_with_selectMax  --利用select top and select max(列) 
 ( 
     @pageIndex int,  --页索引 
     @pageSize int    --页记录数 
 ) 
 as 
 begin 
 set nocount on; 
     declare @timediff datetime 
    declare @sql nvarchar(500) 
    select @timediff=Getdate() 
    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' 
    execute(@sql) 
    select datediff(ms,@timediff,GetDate()) as 耗时 
set nocount off; 
end
 

---3、利用select top和中间变量--此方法因网上有人说效果最佳---

 create procedure proc_paged_with_Midvar  --利用ID>最大ID值和中间变量 
 ( 
     @pageIndex int, 
     @pageSize int 
 ) 
 as 
     declare @count int 
     declare @ID int 
     declare @timediff datetime 
    declare @sql nvarchar(500) 
begin 
set nocount on; 
    select @count=0,@ID=0,@timediff=getdate() 
    select @count=@count+1,@ID=case when @count<=@pageSize*@pageIndex then ID else @ID end from tb_testTable order by id 
    set @sql='select top '+str(@pageSize)+' * from tb_testTable where ID>'+str(@ID) 
    execute(@sql) 
    select datediff(ms,@timediff,getdate()) as 耗时 
set nocount off; 
end 

---4、利用Row_number() 此方法为SQL server 2005中新的方法,利用Row_number()给数据行加上索引

 create procedure proc_paged_with_Rownumber  --利用SQL 2005中的Row_number() 
 ( 
     @pageIndex int, 
     @pageSize int 
 ) 
 as 
     declare @timediff datetime 
 begin 
 set 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 
set nocount off; 
end

---5、利用临时表及Row_number
 create procedure proc_CTE  --利用临时表及Row_number 
 ( 
     @pageIndex int,  --页索引 
     @pageSize int    --页记录数 
 ) 
 as 
     set nocount on; 
     declare @ctestr nvarchar(400) 
     declare @strSql nvarchar(400) 
    declare @datediff datetime 
begin 
    select @datediff=GetDate() 
    set @ctestr='with Table_CTE as 
                (select ceiling((Row_number() over(order by ID ASC))/'+str(@pageSize)+') as page_num,* from tb_TestTable)'; 
    set @strSql=@ctestr+' select * From Table_CTE where page_num='+str(@pageIndex) 
end 
    begin 
        execute sp_executesql @strSql 
        select datediff(ms,@datediff,GetDate()) 
    set nocount off; 
    end
