Running summary in oracle reports 2.5

[jayarammv]

Can somebody tell me how to achieve a Running summary in oracle reports, just like we have in Access reports? Or how to build a query which will have running sum of a column?
like
Column Running Summary
1 1
2 3
3 5

If you have 8i or up you can use something like

SELECT date, amount, SUM(amount) OVER (ORDER BY date)
FROM table

to get the amount and then the cummulative sum of amount by date.
