[oracle] 修改分区表默认表空间

1.创建分区表，使用用户默认表空间

create table par_tab_test
(
id varchar2(20) not null,
time date default sysdate
)
partition by range(time) interval (NUMTODSINTERVAL(1,'DAY'))
(partition part01 values less than(to_date('2021-02-21', 'yyyy-mm-dd')));

2.插入测试数据

insert into par_tab_test values(1,to_date('2021-02-20', 'yyyy-mm-dd'));
insert into par_tab_test values(1,to_date('2021-02-21', 'yyyy-mm-dd'));
insert into par_tab_test values(1,to_date('2021-02-23', 'yyyy-mm-dd'));
commit;

3.查看分区表数据分布

col TABLE_NAME for a20 
col PARTITION_NAME for a20 
select  TABLE_NAME,PARTITION_NAME,TABLESPACE_NAME from dba_tab_partitions where table_name = 'PAR_TAB_TEST';

TABLE_NAME	     PARTITION_NAME	  TABLESPACE_NAME
-------------------- -------------------- ------------------------------
PAR_TAB_TEST	     PART01		      SYSTEM
PAR_TAB_TEST	     SYS_P10178 	  SYSTEM
PAR_TAB_TEST	     SYS_P10179 	  SYSTEM

4.修改默认表空间为users表空间

alter table par_tab_test modify default attributes tablespace users;

5.插入测试数据

insert into par_tab_test values(1,to_date('2021-02-28', 'yyyy-mm-dd'));
commit;

6.查看数据分布

col TABLE_NAME for a20 
col PARTITION_NAME for a20 
select  TABLE_NAME,PARTITION_NAME,TABLESPACE_NAME from dba_tab_partitions where table_name = 'PAR_TAB_TEST';

TABLE_NAME         PARTITION_NAME      TABLESPACE_NAME
-------------------- -------------------- ------------------------------
PAR_TAB_TEST         PART01           SYSTEM
PAR_TAB_TEST         SYS_P10178       SYSTEM
PAR_TAB_TEST         SYS_P10179       SYSTEM
PAR_TAB_TEST         SYS_P10180       USERS

可以看到新插入数据创建在users表空间中。
