Hi all,

I'm trying to return multiple rows from a function, but all I can get
with the code below is the first row.  I got most of the function below
off the net and I think the problem is the first "RETURN" statement,
which stops the loop.

CREATE OR replace function getOnCallVol() RETURNS RECORD AS $$
DECLARE
    r RECORD;
BEGIN
    FOR r IN
            select fname,lname,phone1,phone2,phone3,phone4,phone5
            from events e,volunteer v
            where (now() >= starttime and now()<=endtime and e.v_id =
v.v_id)
            OR (fname='Backup') limit 2

    LOOP
    return r;
    END LOOP;

    RETURN null;

END;
$$ Language plpgsql;

When I run the SQL alone, I get two rows, as I should:
Mary    Smith    1111111111    2222222222    3333333333
Backup    Cellphone    3319993

However, if I run it via the function (i.e. select getOnCallVol()), I
get this:
(Mary,Smith,1111111111,2222222222,3333333333,"","")

Is there another way to get each row returned?  I played around with
making the function return a "SETOF RECORD" and using "RETURN NEXT", but
had no luck.

Thanks,

Bret
