oracle 创建表、以时间戳创建表区间（按月自增）

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  );
 
Table created
1.2 查看现在分区
SQL> select table_name,partition_name from user_tab_partitions where table_name='MONTH_INTERVAL_PARTITION_TABLE';
 
TABLE_NAME                     PARTITION_NAME
------------------------------ ------------------------------

MONTH_INTERVAL_PARTITION_TABLE P_MONTH_1

1.3、插入数据
SQL> begin
  2  for i in 0..11 loop
  3   insert into MONTH_INTERVAL_PARTITION_TABLE values(i,add_months(to_date('2014-01-01','yyyy-mm-dd'),i));
  4  end loop;
  5  commit;
  6  end;
  7  /
 
PL/SQL procedure successfully completed


1.4、查看分区


SQL> select table_name,partition_name from user_tab_partitions where table_name='MONTH_INTERVAL_PARTITION_TABLE';
 
TABLE_NAME                     PARTITION_NAME

------------------------------ ------------------------------
