Yes I am using datepart, but not seeing how with a datediff.
Maybe I just need to do the date math and put a date part on the result.
I will play around a bit when I hit one not looking for days.

O Joel Fradkin ?????? ???? Jan 25, 2005 :
Hi all working my way through our views and all is going very well.
We use datediff in MSSQL a bit and I read about the field1::date -
field2::date to return the days numerically.
Is there any way to get months and years besides guessing days / 30 for
months etc?
Go to
http://www.postgresql.org/docs/7.4/interactive/functions-datetime.html
Check out smth like...
SELECT 'Achilleus is ' || date_part('years',age(timestamp '1969-01-31'))
|| ' years and ' || date_part('months',age(timestamp '1969-01-31')) || '
months old';
               ?column?
-----------------------------------------
Achilleus is 35 years and 11 months old
(1 row)
