建按月日自增分割槽表
阿新 • • 發佈：2019-02-14
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 /

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';
TABLE_NAME PARTITION_NAME
------------------------------ ------------------------------
DAY_INTERVAL_PARTITION_TABLE P_DAY_1
DAY_INTERVAL_PARTITION_TABLE SYS_P34

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檢視資料
SQL> select table_name,partition_name from user_tab_partitions where table_name='DAY_INTERVAL_PARTITION_TABLE';
TABLE_NAME PARTITION_NAME
