oracle下批量增加序列值、批量滚动序列

declare
  VC_SQL varchar2(200);
  N_NUM NUMBER;
begin
  FOR I IN 1 .. 100 LOOP
    for a in (select * from user_sequences) loop
      VC_SQL := 'select ' || a.sequence_name || '.NEXTVAL from dual ';
      execute immediate VC_SQL
        INTO N_NUM;
    end loop;
  END LOOP ;
  end;
