分区表 之 SUBPARTITION TEMPLATE
问题：http://www.itpub.net/581496,2.html
idle>create tablespace tbs1 datafile
2 'd:\ora92\oradata\oracle\tbs1_1.dbf' size 5m;
表空间已创建。
idle>create tablespace tbs2 datafile
2 'd:\ora92\oradata\oracle\tbs2_1.dbf' size 5m;
表空间已创建。

已选择6行。
---当然，你可以通过以下的方法来改变存储的表空间。
idle> alter table AGG_BILL_BY_CITY move subpartition sys_subp11 tablespace tbs1;
表已更改。
idle> alter table AGG_BILL_BY_CITY move subpartition sys_subp12 tablespace tbs2;
表已更改。
idle>select table_name,partition_name,subpartition_name,tablespace_name from user_tab_subpartitions;

AGG_BILL_BY_CITY P20060530 SYS_SUBP11 TBS1
AGG_BILL_BY_CITY P20060530 SYS_SUBP12 TBS2
已选择6行。
----另一种方法，用SUBPARTITION TEMPLATE。
idle>drop table agg_bill_by_city;
表已丢弃。
idle>create table AGG_BILL_BY_CITY

文档上的关于Template

Btw:
我上面做的例子(332)当中，最后一个 add partition前忘了最重要的一个步骤：
idle>alter table test_part MODIFY DEFAULT ATTRIBUTES tablespace tbs4;
表已更改。
修改 test_part的 default attributes 。
