Days betwen dates

От

Anyone know how I can just get the number of
days between dates in 2 columns in a query?

I am using something like age('dateone', 'now')
currently but that returns 1 year 10 mons 14 12:53:10
or something of the like. I just want the days between
them. I am using php. Please let me know if you have
any ideas.

Thanks,
Andy

Actually I found a fix for this (kinda)
There is a function named date_part. And
you can use something like

SELECT date_part('epoch', age('2001-01-24')) / 60 / 60 /24;

I believe that was what I used, and that gives you the days.
I am working from memory at the moment, but that is close.
