五种SQL Server分页存储过程的方法及性能比较

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 

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 

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 

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 

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 

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 

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
