date_part stored procs

Making me lose my cool. Here is how it goes:

I have the following Stored Proc, Which I intend to find the age in months
of a date...


CREATE FUNCTION interval_months(TIMESTAMP) RETURNS INTEGER AS '
DECLARE
docDate ALIAS FOR $1;
len INTEGER;
BEGIN
SELECT INTO len * FROM (SELECT
((date_part(''year'',age(docDate))*12)+(date_part(''month'',age(docDate))))
AS a;
RETURN len;
END
' LANGUAGE 'plpgsql';

The problem is that it does not run and I cannot for the life of me tell
why.


I run it with the following in psql:

select interval_months(file_date) from (select min(file_date) as file_date
from fileattributes) AS a;

And I get the folllowing error:

NOTICE: Error occurred while executing PL/pgSQL function interval_months
NOTICE: line 5 at select into variables
ERROR: parser: parse error at or near ""

I can't see the error, I've lost my mind.... It's friday........
