Re: Need help with this Function. I'm getting an error

Thanks for your response and sorry for my late response. Was away from my
machine. I used your suggestion to complete do away with the union and
instead used the for loop. Also I did not use a temp table or return next. I
got it to work with return query instead. Here's what it looks like:

-- Function: foo_bar()

-- DROP FUNCTION foo_bar();

CREATE OR REPLACE FUNCTION foo_bar()
RETURNS SETOF detailed_phone_inventory_type AS
$BODY$
DECLARE
v_iter_sys_id bigint ;

BEGIN
FOR v_inter_sys_id IN SELECT distinct system_id FROM
inventory_system_properties

LOOP
return query
(select
A.company_name, A.id as system_id,A.name as system_name,B.* from
fetch_cucm_systems() as A
cross join
( SELECT t1.devicepkid,
​[lots more columns]

FROM dblink('dbname=db'||v_iter_sys_id||' user=blah
password=blah123'::text, 'select * from
​​
v_detailed_phone_inventory'::text) t1(devicepkid text,
​[lots more columns]
)
) as B
where A.id=v_iter_sys_id::bigint);
END LOOP;
RETURN;
END;
$BODY$
