Select Query Between two dates...

Question

Hi Guru's,
I need a Select Query between two dates, also if the record not found for any in between date then it should return NULL or 0 ...
for Example
1. I am having two records in DB for date 2-10-2008 & 4-10-2008
2. Now suppose I have given Query for date between 1-10-2008 to 5-10-2008
Then it should return me 5 records with valid values for 2 & 4 and NULL for other 1,3,5
Thanks.

Try like this:
with
  t as
      select date '2008-10-02' as dt, 'Record #1 (in DB)' as str from dual union all
      select date '2008-10-04' as dt, 'Record #2 (in DB)' as str from dual
select v.dt, t.str
  from (
         select date '2008-10-01' + level - 1 as dt
           from dual
         connect by level <= (date '2008-10-05' - date '2008-10-01') + 1
       ) v
  left join t
    on v.dt = t.dt
order by 1
