五種SQL Server分頁預存程序的方法及效能比較_MsSql

在SQL Server資料庫操作中，我們常常會用到預存程序對實現對查詢的資料的分頁處理，以方便瀏覽者的瀏覽。本文我們總結了五種SQL Server分頁預存程序的方法，並對其效能進行了比較，接下來就讓我們來一起瞭解一下這一過程。

建立資料庫data_Test ：

create database data_Test   GO   use data_Test   GO   create table tb_TestTable  --建立表   (   id int identity(1,1) primary key,   userName nvarchar(20) not null,   userPWD nvarchar(20) not null,   userEmail nvarchar(40) null   )   GO 

插入資料：

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進行分頁

具體代碼如下：

create procedure proc_paged_with_notin --利用select top and select not in   (   @pageIndex int, --頁索引   @pageSize int  --每頁記錄數   )   as   begin   set nocount on;   declare @timediff datetime --耗時   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後不支技直接接參數，所以寫成了字串@sql   select datediff(ms,@timediff,GetDate()) as 耗時   set nocount off;   end 

2、利用select top 和 select max(列鍵)

create procedure proc_paged_with_selectMax --利用select top and select max(列)   (   @pageIndex int, --頁索引   @pageSize int  --頁記錄數   )   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 耗時   set nocount off;   end 

3、利用select top和中間變數

create procedure proc_paged_with_Midvar --利用ID>最大ID值和中間變數   (   @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 耗時   set nocount off;   end 

4、利用Row_number() 此方法為SQL server 2005中新的方法,利用Row_number()給資料行加上索引

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 耗時   set nocount off;   end 

5、利用暫存資料表及Row_number

create procedure proc_CTE --利用暫存資料表及Row_number   (   @pageIndex int, --頁索引   @pageSize int  --頁記錄數   )   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 

以上的五種方法中，網上說第三種利用select top和中間變數的方法是效率最高的。
