SQL> set serveroutput on
SQL>  1  begin
  2  for x in (select count(*) count_obj, object_type,
  3                   max(length(object_type)) over (partition by null) max_type,
  4                   max(length(count(*))) over (partition by null) max_count
  5            from dba_objects
  6            group by object_type) loop
  7  dbms_output.put_line(rpad(x.object_type,x.max_type,' ')
  8                       ||' : '||
  9                       lpad(x.count_obj,x.max_count,' '));
10  end loop;
11* end;
