一、建按月自增分區表：

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 查看現在分區
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、插入數據
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、查看分區


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查看其中一個分區數據


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


二、創建按天的分區表


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、查看現在分區
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、插入數據
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查看分區
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查看數據
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
?
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
? ? ? ? ?5 2014/1/6
? ? ? ? ?6 2014/1/7
? ? ? ? ?7 2014/1/8
? ? ? ? ?8 2014/1/9
? ? ? ? ?9 2014/1/10
? ? ? ? 10 2014/1/11
? ? ? ? 11 2014/1/12
? ? ? ? 12 2014/1/13
?
12 rows selected
?
SQL> select * From DAY_INTERVAL_PARTITION_TABLE partition(SYS_P39);
?
? ? ? ? ID TIME_COL
---------- -----------
? ? ? ? ?6 2014/1/7
