1. top分页法
select top pageSize from tb
where ID not in (select top pageSize*pageIndex from tb)
select top pageSize from tb
where ID > select Max(ID) from (select top pageSize*pageIndex from tb) as t
2. RowNum()
select * from (select row_number() over (order by ID) as rowNumber,* from tb) temp where rowNumber between pageSize*(pageIndex-1)+1 and pageSize*pageIndex
