ORACLE创建按月和按天的自动递增分区

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 /

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 /
