怎么利用rownum取得查询出结果，并排过序的后几行数据_Oracle管理

如何利用rownum取得查询出结果，并排过序的后几行数据
前几行的数据可以用

SQL code

SELECT *  FROM (SELECT   col_1, col_2            FROM my_table        ORDER BY col_1) WHERE ROWNUM < 35

假如我有67条记录，后34行的数据应该怎样取得？是在排序的情况下

如果不用rownum有其他的方法可以取到吗？

------解决方案--------------------
select col_1, col_2
from
(SELECT rownum as account, col_1, col_2
FROM my_table
ORDER BY col_1) a
where account>34
看看行不行

类似

SQL codeselect * from(select a.*,row_number() over(order by object_id) as rn from dba_objects a)where rn>64 and rn<=100
------解决方案--------------------
SQL code CREATE TABLE MG_CONT AS    SELECT SYSDATE + LEVEL CONTRACT_ST_DATE FROM DUAL CONNECT BY LEVEL < 68;
