建按月日自增分割槽表

一、建按月自增分割槽表:

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 檢視現在分割槽
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、插入資料
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、檢視分割槽


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檢視其中一個分割槽資料


SQL> select * From MONTH_INTERVAL_PARTITION_TABLE partition(SYS_P22);

        ID TIME_COL
---------- -----------
         0 2014/1/1


二、建立按天的分割槽表


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、檢視現在分割槽
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、插入資料
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檢視分割槽
SQL> select table_name,partition_name from user_tab_partitions where table_name='DAY_INTERVAL_PARTITION_TABLE';

DAY_INTERVAL_PARTITION_TABLE   SYS_P44
DAY_INTERVAL_PARTITION_TABLE   SYS_P45


2.5檢視資料
