Is there a function that will give me the number of months, as an
integer, in Pg 7.4.x? I found the date_trunc function but that will
return text and I didn't see anything else?

I have this, but didn't want to duplicate the work if it wasn't necessary:

(date_part('Year', CURRENT_DATE) -date_part('Year', SOMEDATE)) * 12
+date_part('Month', CURRENT_DATE)-date_part('Month',SOMEDATE)

TIA

You could create your own function for the conversion, something like:

CREATE OR REPLACE FUNCTION interval2Months(INTERVAL) RETURNS INTEGER
LANGUAGE 'sql' IMMUTABLE AS '
SELECT CAST(extract(YEAR FROM $1) * 12 + extract (MONTH FROM $1) AS
INTEGER);
';

you call it doing SELECT interval2Months(age('2003-01-01'::date));

Of course, you can create a function that obtains the age directly from
a DATE parameter and then converts that value to months.

Hope it helps.
