OK. I have the first step done. I'm able to unpivot the table by the following statement.

select year, account, rownum, decode(rownum, 1, Period1, 2, Period2, 3, Period3, 4, Period4, 5, Period5, 6, Period6, 7, Period7, 8, Period8, 9, Period9, 10, Period10, 11, Period11, 12, Period12) from table1, (select rownum from all_objects where rownum <=12)

I am having a hard time summing the periods.

select year, account, rownum, sum(decode(rownum, 1, Period1, 2, Period2, 3, Period3, 4, Period4, 5, Period5, 6, Period6, 7, Period7, 8, Period8, 9, Period9, 10, Period10, 11, Period11, 12, Period12)) from table1, (select rownum from all_objects where rownum <=12) group by year, account

This doesn't seem to work. I just get a null value. Could it have something to do with selecting from the all_objects table?
