Adding columns in a query.

Question

Hello,
I have 12 columns(jan,feb,mar,apr,......dec) in budget table.
Budget table:
year jan feb mar apr may jun jul aug sep oct nov dec
2009 1 2
2010 3 5
2009 3 5 6
I need to add the values of jan,feb,..... in a query and the sum of the same year.
Output of the query for the above table for 2009 should return 1+2+3+5+6=17 and for 2010 3+5=8
Please help me in writing the query to achieve the above result.
Thank u

Something like this?
with t as
    select '2009' Year, 1 Jan, 2 Feb, null Mar, null Apr, null May, null Jun, null Jul, null Aug, null Sep, null Oct, null Nov, null Dec from dual union all
    select '2010' Year, null Jan, null Feb, 3 Mar, null Apr, 5 May, null Jun, null Jul, null Aug, null Sep, null Oct, null Nov, null Dec from dual union all
    select '2009' Year, null Jan, null Feb, 3 Mar, null Apr, 5 May, 6 Jun, null Jul, null Aug, null Sep, null Oct, null Nov, null Dec from dual
select t.Year, sum(nvl(t.Jan,0)+nvl(t.Feb,0)+nvl(t.Mar,0)+nvl(t.Apr,0)+nvl(t.May,0)+nvl(t.Jun,0)+nvl(t.Jul,0)+nvl(t.Aug,0)+nvl(t.Sep,0)+nvl(t.Oct,0)+nvl(t.Nov,0)+nvl(t.Dec,0)) as Year_Sum
from t
group by t.Year
