Returning multiple rows from a function?

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,

Use "RETURNS SETOF record" and "FOR r IN ... LOOP RETURN NEXT; END LOOP;
RETURN;"

You should return "SETOF record". See related section of the manual
about SRFs (Set Returning Fucntions).
