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  );
 
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
------------------------------ ------------------------------
MONTH_INTERVAL_PARTITION_TABLE P_MONTH_1
MONTH_INTERVAL_PARTITION_TABLE SYS_P22
MONTH_INTERVAL_PARTITION_TABLE SYS_P23
MONTH_INTERVAL_PARTITION_TABLE SYS_P24
MONTH_INTERVAL_PARTITION_TABLE SYS_P25
MONTH_INTERVAL_PARTITION_TABLE SYS_P26
MONTH_INTERVAL_PARTITION_TABLE SYS_P27
MONTH_INTERVAL_PARTITION_TABLE SYS_P28
MONTH_INTERVAL_PARTITION_TABLE SYS_P29
MONTH_INTERVAL_PARTITION_TABLE SYS_P30
MONTH_INTERVAL_PARTITION_TABLE SYS_P31
MONTH_INTERVAL_PARTITION_TABLE SYS_P32
MONTH_INTERVAL_PARTITION_TABLE SYS_P33
 
13 rows selected


1.5查看其中一个分区数据


SQL> select * From MONTH_INTERVAL_PARTITION_TABLE partition(SYS_P22);
 
        ID TIME_COL
---------- -----------
         0 2014/1/1


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  );
 
Table created
 
2.2、查看现在分区
SQL> select table_name,partition_name from user_tab_partitions where table_name='DAY_INTERVAL_PARTITION_TABLE';
 
TABLE_NAME                     PARTITION_NAME
------------------------------ ------------------------------
DAY_INTERVAL_PARTITION_TABLE   P_DAY_1


2.3、插入数据
SQL> begin
  2  for i in 1..12 loop
  3   insert into DAY_INTERVAL_PARTITION_TABLE values(i,trunc(to_date('2014-01-01','yyyy-mm-dd')+i));
  4  end loop;
  5  commit;
  6  end;
  7  /
 
PL/SQL procedure successfully completed


2.4查看分区
SQL> select table_name,partition_name from user_tab_partitions where table_name='DAY_INTERVAL_PARTITION_TABLE';
 
TABLE_NAME                     PARTITION_NAME
------------------------------ ------------------------------
DAY_INTERVAL_PARTITION_TABLE   P_DAY_1
DAY_INTERVAL_PARTITION_TABLE   SYS_P34
DAY_INTERVAL_PARTITION_TABLE   SYS_P35
DAY_INTERVAL_PARTITION_TABLE   SYS_P36
DAY_INTERVAL_PARTITION_TABLE   SYS_P37
DAY_INTERVAL_PARTITION_TABLE   SYS_P38
DAY_INTERVAL_PARTITION_TABLE   SYS_P39
DAY_INTERVAL_PARTITION_TABLE   SYS_P40
DAY_INTERVAL_PARTITION_TABLE   SYS_P41
DAY_INTERVAL_PARTITION_TABLE   SYS_P42
DAY_INTERVAL_PARTITION_TABLE   SYS_P43
DAY_INTERVAL_PARTITION_TABLE   SYS_P44
DAY_INTERVAL_PARTITION_TABLE   SYS_P45


2.5查看数据
SQL> select table_name,partition_name from user_tab_partitions where table_name='DAY_INTERVAL_PARTITION_TABLE';
 
TABLE_NAME                     PARTITION_NAME
------------------------------ ------------------------------
DAY_INTERVAL_PARTITION_TABLE   P_DAY_1
DAY_INTERVAL_PARTITION_TABLE   SYS_P34
DAY_INTERVAL_PARTITION_TABLE   SYS_P35
DAY_INTERVAL_PARTITION_TABLE   SYS_P36
DAY_INTERVAL_PARTITION_TABLE   SYS_P37
DAY_INTERVAL_PARTITION_TABLE   SYS_P38

DAY_INTERVAL_PARTITION_TABLE   SYS_P43
DAY_INTERVAL_PARTITION_TABLE   SYS_P44
DAY_INTERVAL_PARTITION_TABLE   SYS_P45
 
13 rows selected
 
SQL> select * From DAY_INTERVAL_PARTITION_TABLE;
 
        ID TIME_COL
---------- -----------
         1 2014/1/2
         2 2014/1/3
         3 2014/1/4
         4 2014/1/5

        10 2014/1/11
        11 2014/1/12
        12 2014/1/13

SQL> select * From DAY_INTERVAL_PARTITION_TABLE partition(SYS_P39);
 
        ID TIME_COL
---------- -----------
