Hello everyone, i have created this function in which i simply want to display a column values through a cursor , but unfortunately i am not getting the column values , this function is showing me simple column name but not the fields in column.
CREATE OR REPLACE FUNCTION foo(id int) returns table(user_id int) as $BODY$ DECLARE r int; DECLARE rs cursor for Select userid from customer where area ='new_york'; BEGIN open rs ; fetch next from rs into r; while (found) loop fetch Next from rs into r; END loop; close rs; END; $BODY$ LANGUAGE plpgsql; i simply want to show all the record from customer table where area is New York but with the help of cursors. thanks
