I am trying to get infinity in an interval type on PostgreSQL 7.4.7.
I can't seem to get this done, even though there's allegedly an
isfinite(interval) function. For now we use NULL instead, but what would
have worked?
Next to that I noticed:
select age('infinity'::timestamp);
age
-------------------------------------------------
-292270 years -8 mons -11 days -04:00:54.775807
(1 row)
Another problem we have is that we want to extract the value and the
unit seperately from our intervals, mainly to cast them to something
that can be used in PHP and HTML forms. We don't need to calculate on
them in PHP, but we'd like to split the number and the type into a text
and a drop-down field.
I realize that this isn't possible for intervals like '1 year 3 months',
but we only use relatively simple intervals like '3 months', '6 weeks'
and '100 hours'.
Is there some easy way to query such intervals in a way that can be
reliably split up?
Regards,
