一、建按月自增分区表：
1.1建表
SQL> create table month_interval_partition_table (id number,time_col date) partition by range(time_col)
  2  interval (numtoyminterval(1,'month'))
  3  (
  4  partition p_month_1 values less than (to_date('2014-01-01','yyyy-mm-dd'))
  5  );



二、创建按天的分区表


2.1建表
SQL> create table day_interval_partition_table (id number,time_col date) partition by range(time_col)
  2  interval (numtodsinterval(1,'day'))
  3  (
  4  partition p_day_1 values less than (to_date('2014-01-01','yyyy-mm-dd'))
  5  );
