分页-存储过程5种写法 sqlserver分页

在SQL Server数据库操作中，我们常常会用到存储过程对实现对查询的数据的分页处理，以方便浏览者的浏览。本文我们总结了五种SQL Server分页存储过程的方法，并对其性能进行了比较，接下来就让我们来一起了解一下这一过程。

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,GetDate())?as?耗时?? ?
  
  
?
  
  
set?nocount?off;?? ?
  
  
?
  
  
end?
 
 

3、利用select top和中间变量

 
 

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,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,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
