What you need is a table that has all the dates you want a report on
already in it to join against. Just something like:

day
---
1
2
3
4
5
6
7
...
29
30
31 <- or fewer for other months.

Just make a temp table to hold the days. Then join against that using
extract().

If you get stuck let us know.
