title: execute immediate for tables having number in their names
body: <p>I have a execute immediate in my package and when the <code>v_object_name</code> is something like 20200823_AGL, I get this error:</p>
  <blockquote>
  <p>ORA-00903: Invalid table name</p>

  <pre><code>EXECUTE IMMEDIATE 'SELECT MAX(LAST_UPDATE),COUNT(*) FROM ' || v_object_name || ''
                                                                   INTO v_max_update_date,
                                                                        v_count;
