VS2005中用存储过程实现分页控件AspNetPager(用存储过程加AspNetPager分页控件分页超快)

存储过程:(这里用到的数据库是MSSQL2000中自带的数据库Northwind中的表order)

CREATE procedure pro_order
(@pagesize  int ,
@pageindex  int ,
@docount bit)
as
set  nocount on
if (@docount = 1 )
select count(OrderID) from Orders
else
begin
declare @indextable table(id  int  identity( 1 , 1 ),nid  int )
declare @PageLowerBound  int
declare @PageUpperBound  int
set  @PageLowerBound = (@pageindex - 1 ) * @pagesize
set  @PageUpperBound = @PageLowerBound + @pagesize
set  rowcount @PageUpperBound
insert into @indextable(nid) select OrderID from Orders order by RequiredDate desc
select O. *  from Orders O,@indextable t where O.OrderID = t.nid
and t.id > @PageLowerBound and t.id <= @PageUpperBound order by t.id
end
set  nocount off
