try this
select res_id,
trunc(sysdate)+hr/24
from cal, (select level hr from dual connect by level<25)
where
sd<trunc(sd)+(hr+1)/24
and ed>trunc(sd)+hr/24
order by 1,hr;
you may have to tweak the where to get the data exactly as you want
(e.g. if the staring date is between 8 and 9, should you get 8 or not?)

I am writing a scheduling application in apex. Resources are reserved
by hour. I need a calendar to show when resources are reserved.
In the 'day view' of that calendar I need the schedule split out by
hour.
Resource_id number
Start_res date
End_res date
If I have a row like: 1, Jan 01 2008 8am, Jan 01 2008 10am, I need the
query to return:
1, Jan 1 2008 8am
1,Jan 1 2008 9am
So far I've been unable to come up with the sql. Anybody got a quick
answer?
It is amazing how hard sql seems when you haven't had to write anything
of any substance in a long time.
Thanks!
