As long as both adate and bdate are relative to the same date the first query:

Select *
  from timetable
 where (adate-bdate) > 20 * 60;

is OK.

I am trying to get this sql statement working. All the dates are stored in number field in seconds starting from 1-JAN-1970.
-- All records where adate - bdate is greater than 20
minutes.

Select * from timetable
where (adate - bdatae) > 20 minutes;
-- All records where sydate - bdate > 20 minutes
select * from timetable
where (sydate - bdate) > 20 minutes;

I tried the following and I am not sure whether I am right.

Select * from timetable
where ((adate-bdate) > 20 * 60); --( which will give 20 minutes)

select * from timetable
where
(sysdate-20/1440)-to_date('01-JAN-1970','DD-MON-YYYY')+bdate(24*60*60)>2 0);

TIA Loren
