Oracle查询某段日期内某个时间段的数据

示例：

查询最近一周12:30分到13:00这段时间内的订单量：

SELECT *
  FROM T_ORDER O
 WHERE O.CREATEDATETIME BETWEEN
       SYSDATE-7 AND
       SYSDATE
   AND TO_CHAR(O.CREATEDATETIME, 'hh24:mi:ss') BETWEEN '12:30:00' AND
       '13:00:00'

 

查询某段日期内某个时间段的订单量：

SELECT *
  FROM T_ORDER O
 WHERE O.CREATEDATETIME BETWEEN
       TO_DATE('2016-10-08 12:30', 'yyyy-mm-dd hh24:mi') AND
       TO_DATE('2016-10-14 13:00', 'yyyy-mm-dd hh24:mi')
   AND TO_CHAR(O.CREATEDATETIME, 'hh24:mi:ss') BETWEEN '12:30:00' AND
       '13:00:00'

主要是思路。。。
