hi , i have created this function
CREATE OR REPLACE FUNCTION totaloverlapcount(user_id integer , bg integer ,center_distance integer)
RETURNS varchar AS $$
DECLARE percentage record;
BEGIN
select fname, lname, count(userid) totalcount ,100.00*count(useriddetails)/totaluser into percentage
from users
where userid= user_id and bloodgroup>=bg and
(centredistance<=center_distance or center_distance=1)
group by fname, lname, user_id;
return percentage;
its just a dummy function , but all i want to know that how can i return fname , lname totalcount and percentage from this function in the form of table , not the return type varchar.
thanks
