I am sorry I didn’t clarify my requirement properly.. I want the ‘n’ oldest records, however, they should sorted with the recent record first and I want this to happen in the query itself so I don’t have to care about sorting through the application..

this will return the recent 5 records.. what I want is the oldest 5 records (in last 30 days)
so remove "desc", in order to have ascending ordering, thus first 5 records are the five oldest:
select * from t order by record_date limit 5
