Обсуждение: date subtraction

I need to do date calculation similar to oracle in postgres.

like sysdate - creation_date of the record which returns no
of days in oracle which you can convert to hours or second
by multiplying by 60 or 3600.

How do i achieve this in postgres.

Thanks
Ashok

Umm,  SELECT CURRENT_DATE - creation_date FROM my_table;
