------创建数据库data_Test -----create database data_TestGOuse data_TestGOcreate 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
begininsert into tb_TestTable(id,userName,userPWD,userEmail) values(@count,'admin','admin888','lli0077@yahoo.com.cn')
set @count=@count+1
endset 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
)asbeginset 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
)asbeginset nocount on;
declare @timediff datetimedeclare @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
)asdeclare @count int
declare @ID int
declare @timediff datetimedeclare @sql nvarchar(500)beginset 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
)asdeclare @timediff datetimebeginset nocount on;
select @timediff=getdate()
select * from (select *,Row_number() over(order by ID asc) as IDRank from tb_testTable) as IDWithRowNumber whereIDRank>@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_numbercreate procedure proc_CTE --利用临时表及Row_number(@pageIndex int, --页索引
@pageSize int --页记录数
)asset nocount on;
declare @ctestr nvarchar(400)declare @strSql nvarchar(400)declare @datediff datetimebeginselect @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)
endbeginexecute sp_executesql @strSqlselect datediff(ms,@datediff,GetDate())
set nocount off;
