Retrieving multiselect values from database

Question

Hi,
I have a multiselect list of companies names for a user.
An application user can belong to one or more company. The application user gets to see data in the application based on the company/companies that he belongs to.
When a user belongs to more than one company the company is saved in the database as example :013:113 for a user.
I have written a function which retrieves the company code of a user. This function is then called in my codes in apex to restrict the data the user can see.
create or replace
function get_company_code (p_usr_name in fus_users.usersname%type)
return t_com_table
is
  -- Cursor to get the company for a user
  cursor c_usr2 (b_usr_name in fus_users.username%type) is
    select usr.mdr_com_code
    from   fus_users  usr
    where  upper(usr.username) in upper(b_usr_name)
  cursor c_usr1 (b_usr_name in fus_users.username%type) is
    select distinct mdr.com_code
    from   fus_medewerkers  mdr
   cursor c_usr (b_usr_name in fus_users.username%type) is
    select usr.super_admin
    from   fus_users  usr
    where  upper(usr.username) in upper(b_usr_name)
  l_retval t_com_table;
  l_super_admin t_sup_admin_table;
  begin
    for r_usr in c_usr(b_usr_name => p_usr_name)
    loop
    if r_usr.super_admin is not null then
     open  c_usr1(b_usr_name => p_usr_name);
     fetch c_usr1 bulk collect into l_retval;
     close c_usr1;
    else
     open  c_usr2(b_usr_name => p_usr_name);
     fetch c_usr2 bulk collect into l_retval;
     close c_usr2;
    end if;
    end loop;
    return l_retval;
  end get_company_code; The code works fine when a user belongs to one company.
How do i get the companies code in my type as rows when a user belongs to more than one company?

Hi Varad and Kofi,
I finally got my code working :)
create or replace
function get_company_code (p_usr_name in fus_users.username%type)
return t_com_table pipelined
is
  l_com_code varchar2(50);
  l_tab wwv_flow_global.vc_arr2;
  type type_coll_com_code is table of varchar2(5);
  t_com_code type_coll_com_code;
  -- Cursor to get the company for a not super_admin user
  cursor c_usr2 (b_usr_name in fus_users.username%type) is
    select usr.mdr_com_code
    from   fus_users  usr
    where  upper(usr.username) in upper(b_usr_name)
-- Cursor to get the company for a super_admin user
  cursor c_usr1 (b_usr_name in fus_users.username%type) is
    select  distinct mdr.com_code
    from   fus_medewerkers  mdr
  -- Cursor to get super_admin
   cursor c_usr (b_usr_name in fus_users.username%type) is
    select usr.super_admin
    from   fus_users  usr
    where  upper(usr.username) in upper(b_usr_name)
  begin
    for r_usr in c_usr(b_usr_name => p_usr_name)
    loop
    if r_usr.super_admin is not null then
     open  c_usr1(b_usr_name => p_usr_name);
     fetch c_usr1  bulk collect
     into t_com_code ;
     close c_usr1;
     for i in 1..t_com_code.count loop
     pipe row (t_com_code(i));
     end loop;
    else
     open  c_usr2(b_usr_name => p_usr_name);
     fetch c_usr2  into l_com_code;
     l_tab:= apex_util.string_to_table(l_com_code); 
     close c_usr2;
     for i in l_tab.first..l_tab.last loop
     pipe row (trim(l_tab(i)));
     end loop;
    end if;
    end loop;
    return ;
  end get_company_code; Thanks for the help.
