Answer 1

As already explained, you need to give us more detail.
Why are you wanting to returns a record set, rather than just return a ref cursor (sys_refcursor)?
e.g. The following function returns a ref cursor to the calling code (in my case the calling code is SQL*Plus)...
SQL> ed
Wrote file afiedt.buf
  1  create or replace function get_dept(p_deptno in number) return sys_refcursor is
  2    v_rc sys_refcursor;
  3  begin
  4    open v_rc for 'select * from emp where deptno = :1' using p_deptno;
  5    return v_rc;
  6* end;
SQL> /
Function created.
SQL> var x refcursor;
SQL> exec :x := get_dept(20);
PL/SQL procedure successfully completed.
SQL> print x;

SQL>It is SQL*Plus that get's the ref cursor back and then does the fetch on that cursor to retrieve the records and display them using it's "print" command.
In another language, it would get the ref cursor and then process the rows by fetching them as appropriate for that language.
You don't need the function/procedure to fetch all the data into some sort of type structure and try and pass it all back.
