If I can assume Month_1..Month_120 as fields of your table rather than variables, then I suppose we can do things like this:

I= 1;
while (I <= NoOfCol) do
begin
s= 'update YOUR_TABLE set Month_'||I||' = Month_'||I||' + ? where SOME_CONDITION';
execute statement (s) (nTotalMonth);
I= I+1;
end

"YOUR_TABLE" & "SOME_CONDITION" are just symbolic, sorry to be wordy

This approach is only good in syntax, in real performance I think it will be a bit slower than your long syntax, because of the run time compilation of EXECUTE STATEMENT.

So the report is ran for the first year 10/01/12 thru 06/30/13 and is a 9 x 9 report (9 rows - Periods x 9 columns - Monthly collections).
