Answer 1

you can use piplined table, it should be something like this:

create or replace type year_date_typ as object (v_day date);
create or replace type year_date_tab as table of year_date_typ;

CREATE OR REPLACE FUNCTION get_dates(year IN VARCHAR2) RETURN year_date_tab PIPELINED IS
v_start_date date := to_date('0101' || year, 'ddmmyyyy');
res year_date_typ := year_date_typ(null);
v_days_in_year integer := 365;
BEGIN
if to_char(last_day(to_date('0102'||year, 'ddmmyyyy')), 'dd') = '29' then
v_days_in_year := 366;
end if;
FOR i in 0 .. v_days_in_year integer-1 LOOP
res.v_day := v_start_date + i;
pipe row(res);
END LOOP;

return;
END get_dates;

and you can use it:

select * from table(get_dates('2011'));
