使用存储过程创建分页

在实际的开发过程中，经常遇到存储过程分页，下面根据实际情况总结的几种方法：

数据库名称：myTest

1、思路：利用select top and select not in 排除例外情况的分页
use myTest
go
create procedure proc_paged_with_notin
(
@pageIndex int, --页索引
@pageSize int --每页记录数
)
as
begin
set nocount on; --没有返回值
declare @sql nvarchar(500)
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后不支持直接接参数，所以写成了字符串@sql
set nocount off;
end

exec proc_paged_with_notin 10,5

2、思路：利用select top and select max(列)分页
use myTest
go
create procedure proc_paged_with_selectMax
(
@pageIndex int, --页索引
@pageSize int --每页记录数
)
as
begin
set nocount on;
declare @sql nvarchar(500)
if @pageIndex=0
set @sql='select top '+str(@pageSize)+' * from tb_TestTable order by ID'
else
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)
set nocount off;
end

exec proc_paged_with_selectMax 10,5

3、思路：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
begin
set nocount on;
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)
set nocount off;
end

exec proc_paged_with_Rownumber 10,5

三种方法的测试结果显示：select max >row_number>not in（分页速度）
