如何在oracle中接收游标变量并得到值

declare
    v_result number;
    type v_cursor is ref cursor;
    v_cur v_cursor;
    v_row nanProductInfo%rowtype;
begin 
   OperaToNanInfo.DORESEARCH(v_result,v_cur);
   dbms_output.PUT_LINE(v_result);
   fetch v_cur into v_row;
   while v_cur%found
      loop
          dbms_output.PUT_LINE(v_row.name);
          fetch v_cur into v_row;
     end loop;
end;
