Thread: to_char(interval) ?

to_char(interval) ?

From

how do I get an interval '1 day 1 hour' to display as
'25 hours'. I am hunting in the docs (and googling)
and either I am blind or I need a special function?

Is there an easy way?

EXTRACT epoch from the interval and divide by 3600 and concatenate to ' hours'.

area=> select extract(epoch from '1 day 1 hour'::interval)/3600 || ' hours';?column?
----------25 hours
(1 row)

This is perfect.

select extract(epoch from '1 day 1 hour 15
minute'::interval)/3600 || 'hours'; ?column?  
------------25.25hours
(1 row)

I must have looked at this for hours and not seen the
'interval' part of the epoch...

Thanks,

Ted
