五种常用存储过程：
1，利用select top 和select not in进行分页，具体代码如下：
1 create procedure proc_paged_with_notin --利用select top and select not in
2
(
3 @pageIndex int, --页索引
4 @pageSize int --每页记录数
5)
6as
7begin
8 set nocount on;
9 declare @timediff datetime --耗时
10 declare @sql nvarchar(500)
11 select @timediff=Getdate()
12 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'
13 execute(@sql) --因select top后不支技直接接参数，所以写成了字符串@sql
14 select datediff(ms,@timediff,GetDate()) as 耗时
15 set nocount off;
16end
2,利用select top 和 select max(列键)
1create procedure proc_paged_with_selectMax --利用select top and select max(列)
2(
3 @pageIndex int, --页索引
4 @pageSize int --页记录数
5)
6as
7begin
8set nocount on;
9 declare @timediff datetime
10 declare @sql nvarchar(500)
11 select @timediff=Getdate()
12 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'
13 execute(@sql)
14 select datediff(ms,@timediff,GetDate()) as 耗时
15set nocount off;
16end
3,利用select top和中间变量--此方法因网上有人说效果最佳，所以贴出来一同测试
1create procedure proc_paged_with_Midvar --利用ID>最大ID值和中间变量
2(
3 @pageIndex int,
4 @pageSize int
5)
6as
7 declare @count int
8 declare @ID int
9 declare @timediff datetime
10 declare @sql nvarchar(500)
11begin
12set nocount on;
13 select @count=0,@ID=0,@timediff=getdate()
14 select @count=@count+1,@ID=case when @count<=@pageSize*@pageIndex then ID else @ID end from tb_testTable order by id
15 set @sql='select top '+str(@pageSize)+' * from tb_testTable where ID>'+str(@ID)
16 execute(@sql)
17 select datediff(ms,@timediff,getdate()) as 耗时
18set nocount off;
19end
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
1create procedure proc_paged_with_Rownumber --利用SQL 2005中的Row_number()
2(
3 @pageIndex int,
4 @pageSize int
5)
6as
7 declare @timediff datetime
8begin
9set nocount on;
10 select @timediff=getdate()
11 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)
12 select datediff(ms,@timediff,getdate()) as 耗时
13set nocount off;
14end
5，利用临时表及Row_number
1create procedure proc_CTE --利用临时表及Row_number
2(
3 @pageIndex int, --页索引
4 @pageSize int --页记录数
5)
6as
7 set nocount on;
8 declare @ctestr nvarchar(400)
9 declare @strSql nvarchar(400)
10 declare @datediff datetime
11begin
12 select @datediff=GetDate()
13 set @ctestr='with Table_CTE as
14 (select ceiling((Row_number() over(order by ID ASC))/'+str(@pageSize)+') as page_num,* from tb_TestTable)';
15 set @strSql=@ctestr+' select * From Table_CTE where page_num='+str(@pageIndex)
16end
17 begin
18 execute sp_executesql @strSql
19 select datediff(ms,@datediff,GetDate())
20 set nocount off;
21 end
