I guess the best way to get the output I wanted was to do the following:
define startDate = to_date('2013-10-01', 'yyyy-mm-dd')
select type,
sum(case when MyDate = &&startDate then 1 else 0 end) as "1"
, sum(case when MyDate = &&startDate +1 then 1 else 0 end) as "2"
, sum(case when MyDate = &&startDate +2 then 1 else 0 end) as "3"
, sum(case when MyDate = &&startDate +3 then 1 else 0 end) as "4"
...etc for as many days of current month I am running
, sum(case when MyDate = &&startDate +29 then 1 else 0 end) as "30"
, sum(case when MyDate = &&startDate +30 then 1 else 0 end) as "31"--This would be commented out for Nov
from MyTabe
group by type
order by type
;
This way if I want to run this for Nov, Dec, Jan, and so on, I can just change the variable at the top and run the query. This is what I was looking for; however, I still wonder if it would be possible to generate the columns dynamically, but the more I look at it, the more I think that would require a pivot table.
