Running Total by Group SQL (Oracle)

Ah, I think I have figured it out.

select a.*, sum(Amount) over (partition by Location, Product order by Date) as Running_Amt
from Example_Table a

from Advanced SQL Functions in Oracle 10g book, it has this example.

SELECT dte "Date", location, receipts,
SUM(receipts) OVER(ORDER BY dte
ROWS BETWEEN UNBOUNDED PRECEDING
AND CURRENT ROW) "Running total"
FROM store
WHERE dte < '10-Jan-2006'
ORDER BY dte, location

I could type out all the answer or send you to where I learned it. :)
