     results :=smpl_metadata_table();
     results.extend;
     results(results.count).tmp_click_num := count1;
     results(results.count).tmp_reach_num := count2;
     results(results.count).tmp_trigger_num := count3;
     return(results);
    end if;
  end loop;
   
end fn_test;

我想得到的结果是,查询这几张表的count,然后用表值函数返回
