Help Select Query

i have the table with the following structure and data

Values
1
2
3
4
5

so i want a query to this follows output

Values SumVal
1 1
2 3
3 6
4 10
5 15

What exactly is the second colum of what you want to do? Is it a count of How many? Or does it add all the 1's , all the 2's etc. You need to be more specific.

Where's the
1
3
6
10
15
coming from???

The second column value is
when first value of first coloum is selected the sumvalue should be 1
when second value of first column is selected(2) the sumvalue should be sum of selected(2) value and the sum of previous value(1) ie

value sumvalue
1 1
2 3

when third value of first column is selected(3) the sumvalue should be sum of selected(3) value and the sum of previous values(1+2) ie 3+1+2=6

when third value of first column is selected(4) the sumvalue should be sum of selected(4) value and the sum of previous values(1+2+3) ie 4+1+2+3=10
and so on

declare @i integer
set @i=1
create table #test (col1 integer,col2 integer)
while @i<10
begin
insert into #test (col1) values (@i)
set @i=@i+1
end
update #test set col2=(select sum(col1) from #test a where a.col1<=#test.col1)
select * from #test
drop table #test
