problems with pgplsql looping through query results (FOR row IN)

Hi,

Trying to get grip on FOR row IN select clause using this
testfunction.

The FOR row|record in is the one I can't get to work.

CREATE FUNCTION dosomething (varchar)
RETURNS integer
AS '
DECLARE
_conn_id ALIAS FOR $1;
ts integer;
cdrrec record;
BEGIN
ts := 0;
FOR row IN
SELECT *
FROM cdr_accounting
WHERE connection_id = _conn_id
LOOP
ts := ts + row.time_stamp
END LOOP;

return ts;
END;'
LANGUAGE 'plpgsql';

How to get this one to work ?

Thanks,
