Great videos - thanks for sharing. In this case you could also use a WINDOW function like this: SELECT id, amt, sum(amt) OVER (ORDER BY id) FROM ledger;

Yes this works unless you want to order by date and then you have problems. So you can switch your id parts to date, but then the problem is if you have two entries with the same date. So this is where I am stuck
