[SQL] date_part stored procs

[Tsoloane Moahloli]

Title: Message

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........
