Populating a collection with function results

Question

I am calculating some statistics and need to use a collection to store the results of several function so they can be used in a procedure. Example:
PROCEDURE PRODUCTIVITY_INSERT(p_first_of_month IN DATE)
AS
BEGIN
vc_FirstofMonth := p_first_of_month;
FOR i IN 1..3 loop
EXECUTE IMMEDIATE 'INSERT INTO RFC_BUS'||days(i)||'PRODUCTIVITY(ROUTE,PPPH)
SELECT a.route, ((sr05 / sy05)/'||counts(i)||') AS "RATIO"
FROM (SELECT route,
SUM (DECODE (TO_CHAR (pick, "MM-YYYY"),
to_char(vc_FirstofMonth, "MM-YYYY"), platform_hours, null)) AS sy05
FROM bus_platformhours
WHERE day_type ='||days(i)||' and platform_hours > 0
GROUP BY route) a,
(SELECT route,
SUM (DECODE (TO_CHAR (service_date, "mm-yyyy"),
to_char(vc_FirstofMonth, "MM-YYYY"), rides, null)) AS sr05
FROM bush_daily_rides
WHERE day_type = '||days(i)||
'GROUP BY route) b
WHERE a.route = b.route
ORDER BY a.route
VALUES(
p_route,
p_ratio
) USING days(i), counts(i)';
end loop;
Can I use collections to hold the function results (say three function out variables) while they are being looped through in the procedure? If I can do that I am presuming I use the functions name in the collection such as:
TYPE dayoneList IS TABLE OF NUMBER;
dayone dayoneList := dayoneList(wkdaysminusone(), sadaysminusone(), sudaysminusone());
thanks for any help you can give me.

Answer 1

Do you mean to use the functions as the elements of collection constructor ?
It's possible:
SQL> create function get_one return number is begin return 1; end;
  2  /
Function created.
SQL> create function get_two return number is begin return 2; end;
  2  /
Function created.
SQL> declare
  2   type arr is table of number;
  3   arr1 arr := arr(get_one(), get_two());
  4  begin
  5   for i in 1..arr1.count loop
  6    dbms_output.put_line(arr1(i));
  7   end loop;
  8  end;
  9  /
