关于高效分页

分页规律

方法1（最常用）：

start：(pageIndex-1)*pageSize+1 end：pageIndex*pageSize

select * from (select *,row_number() over(order by Id desc) as rowIndex from tb_Person where RowIndex) as tb_new where rowIndex between (@pageIndex-1)*@pageSize+1 and @pageIndex*@pageSize

方法2（靠前面和后面的页面查询速度快）越过多少行 取多少行

select top（@pageSize）*

from tb_News where ID not exits in

select top (@pageIndex-1)*@pageSeze * from tb_News ;
