Hi,
assuming I have a query that computes a running sum like this:
select id, buy_price, sum(buy_price) over (order by id) sum
from fmb
where 202300<=id and id<=202400
order by id;
Do I need the ORDER BY clause at the end? Or does the ORDER BY in the
window function already define the order of the result set?
Thanks,
Torsten
