Wei,
This should work for you:
create table #MyTable (Price decimal(9,2), Amount int)
insert #MyTable select 99.5, 10000
insert #MyTable select 99.7, 8000
insert #MyTable select 100, 3000
insert #MyTable select 100.1, 1000
insert #MyTable select 100.5, 500
insert #MyTable select 100.8, 1500
insert #MyTable select 105, 2000
insert #MyTable select 200, 100
select
cast(Price + .5 as int) Price
, sum(Amount) SumOfAmount
from #MyTable
group by
cast(Price + .5 as int)
order by
cast(Price + .5 as int)
-- Bill
