Howto make view from this query?

Question

Dear forum members,
I have a cursor like this:
  for email_record IN (
    select distinct email_address_1 email_address
    from cl_employees
    where employees_pk in (
      (select responsible_fk from cl_jobs where jobs_pk=l_jobs_pk)
      union
      (select cutter_fk from cl_jobs where jobs_pk=l_jobs_pk)
      union
      (select line_producer_fk from cl_jobs where jobs_pk=l_jobs_pk))) LOOP
        if email_record.email_address is not null then
          l_to:=l_to||email_record.email_address||',';
        end if;
        l_counter:=l_counter+1;
      end loop;Is there any posibility to make a view out of this select statement, so that the cursor will be something like:
  for email_record IN (
    select email_address
    from view_mailaddresses
    where jobs_pk=l_jobs_pk) LOOP
        if email_record.email_address is not null then
          l_to:=l_to||email_record.email_address||',';
        end if;
        l_counter:=l_counter+1;
      end loop;Thanks in advance
Johann
