Hi!

I have one table with dates (say 20th - 30th January), and other table with transactions and dates:
Date | Transaction
2012-01-20 300$
2012-01-22 -100$
2012-01-25 500$
...

I want to display something like this:
Date | Total money (on each day)
2012-01-20 300$
2012-01-21 300$
2012-01-22 200$
2012-01-23 200$
2012-01-24 200$
2012-01-25 700$
...

So, I want to sum every transaction up to each row date. Can't figure this one out...

[code]
select t1.date, (select sum(transaction) from table2 t2 where t2.date <= t1.date)
from table1 t1
[/code]
