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
