Calling packaged procedure from a function

Question

Hi all,
I am using Oracle database 10.2.0
I have a packaged procedure , there are two IN parameters(Varchar, Date) and an OUT parameter(REF CURSOR). The out parameter sends a result set from a query(multiple records of a table). I was asked to create a function which can use this procedure and returns the same resultset. Can u please suggest how to proceed?
Thanks & Regards,
Naveen.

Is it something like this you're after:
SQL> create or replace function test_f (p_In1 in number, p_In2 in varchar2) return sys_refcursor as
  2    r sys_refcursor;
  3    begin
  4      open r for 'select ' || to_char(p_In1) || ',''' || p_In2 || ''' from dual';
  5      return  r;
  6  end test_f;
  7  /
Function created.
SQL> declare
  2    r sys_refcursor;
  3   
  4    l_no number;
  5    l_Greet varchar2(30);
  6  begin
  7    r := test_f(1, 'Hello');
  8   
  9    fetch r into l_no, l_Greet;
10    if (r%found) then
11      dbms_output.put_line(l_No || ' ' || l_Greet);
12    end if;
13   
14    close r;
15   
16    exception
17      when others then
18        dbms_output.put_line('Err ' || sqlerrm);
19        if (r%isopen) then
20          close r;
21        end if;
22 
23  end;
24  /
