一、实验目的
採用List-Range分区，对主分区指定表空间或者对子分区指定表空的不同情况，測试例如以下内容：
1、对List主分区不指定表空间。对Range子分区指定表空间，数据实际存储在哪个表空间；追加List主分区不指定Range子分区和指定Range子分区时，Oracle怎样创建相关子分区；
2、对List主分区指定表空间，对Range子分区不指定表空间。数据实际存储在哪个表空间；追加List主分区不指定Range子分区和指定Range子分区时，Oracle怎样创建相关子分区；
二、实验环境
操作系统：Window 7 旗舰版 x64
Cpu：Intel i5-2520M 2.50GHz X 2
内存：10G
Oracle版本号：Release 11.2.0.1.0

4.3.2、查看分区
查看主分组
select partition_position,table_name,partition_name,high_value,tablespace_name,num_rows
from user_tab_partitions
where table_name='LST_RNG_RANGE';
未指定表空间的主分区，默认使用当前用户所在的表空间。
查看子分区
select subpartition_position,table_name,partition_name,subpartition_name,high_value,tablespace_name,num_rows
from user_tab_subpartitions
where table_name='LST_RNG_RANGE';
4.3.3、插入数据
INSERT INTO LST_RNG_RANGE(AUTO_ID,SALE_NO,POS_CODE,POS_NAME,TOTAL_AMOUNT,SALE_DATE,REMARK)
VALUES(SYS_GUID(),'SN201507240001','3512860005','新干线贸易有限公司','100.78',TO_DATE('2015-07-24','YYYY-MM-DD'),NULL);
INSERT INTO LST_RNG_RANGE(AUTO_ID,SALE_NO,POS_CODE,POS_NAME,TOTAL_AMOUNT,SALE_DATE,REMARK)
VALUES(SYS_GUID(),'SN201507250001','3512860005','新干线贸易有限公司','100.78',TO_DATE('2015-07-25','YYYY-MM-DD'),NULL);
INSERT INTO LST_RNG_RANGE(AUTO_ID,SALE_NO,POS_CODE,POS_NAME,TOTAL_AMOUNT,SALE_DATE,REMARK)
VALUES(SYS_GUID(),'SN201507240001','3512860010','全味食品商贸有限公司','100.78',TO_DATE('2015-07-24','YYYY-MM-DD'),NULL);
INSERT INTO LST_RNG_RANGE(AUTO_ID,SALE_NO,POS_CODE,POS_NAME,TOTAL_AMOUNT,SALE_DATE,REMARK)
VALUES(SYS_GUID(),'SN201507250001','3512860010','全味食品商贸有限公司','100.78',TO_DATE('2015-07-25','YYYY-MM-DD'),NULL);
commit;
4.3.4、查看数据
查看分区数据
select * from LST_RNG_RANGE partition(P_3512860010);
select * from LST_RNG_RANGE partition(P_3512860005);
select * from LST_RNG_RANGE subpartition(P_3512860010_SP_20150726);
select * from LST_RNG_RANGE subpartition(P_3512860005_SP_20150726);
收集分区统计信息
begin
dbms_stats.gather_table_stats(ownname=>'WKOD_VERIFY',granularity =>'all',tabname=>'LST_RNG_RANGE',cascade=>true);
end;
查看主分组
select partition_position,table_name,partition_name,high_value,tablespace_name,num_rows
from user_tab_partitions
where table_name='LST_RNG_RANGE';
num_rows=2，LST_PNG_RANGE表的两个主分区在当前用户所在的表空间中各有2条数据
查看子分区
select subpartition_position,table_name,partition_name,subpartition_name,high_value,tablespace_name,num_rows
from user_tab_subpartitions
where table_name='LST_RNG_RANGE';
两个分区在同一个表空间中，每一个分区中都存在两条数据
4.3.5、追加分区
方式一：追加主分区
alter table LST_RNG_RANGE add partition P_3512834993 values ('3512834993')
查看分区
select partition_position,table_name,partition_name,high_value,tablespace_name,num_rows
from user_tab_partitions
where table_name='LST_RNG_RANGE';
主分区所属表空间为当前用户所在的表空间
查看子分区
select subpartition_position,table_name,partition_name,subpartition_name,high_value,tablespace_name,num_rows
from user_tab_subpartitions
where table_name='LST_RNG_RANGE';
默认依照表创建时子分区的的分区规则，自己主动生成一个子分区（红色框内），且分区相应表空间与原来一致
删除加入的List分区
alter table LST_RNG_RANGE drop partition P_3512834993;
相应的子分区会自己主动被drop掉。
方式二：追加主分区及其子分区
alter table LST_RNG_RANGE add partition P_3512834993 values ('3512834993')
(subpartition P_3512834993_SP_20150802 values less than (TO_DATE('2015-08-02','YYYY-MM-DD')) tablespace TS_20150809)
查看分区
select partition_position,table_name,partition_name,high_value,tablespace_name,num_rows
from user_tab_partitions
where table_name='LST_RNG_RANGE';
主分区所属表空间为当前用户所在的表空间
查看子分区
select subpartition_position,table_name,partition_name,subpartition_name,high_value,tablespace_name,num_rows
from user_tab_subpartitions
where table_name='LST_RNG_RANGE';
依照设定的子分区所属的表空间创建range子分区
五、实验结论
一、List-Range组合分区下。在List指定表空间，Range不指定表空间。Oracle自己主动将Range子分区存放于相应的List表空间中。
二、追加分区时候。在不指定子分区的情况下，Oracle默认依照表创建时的分区方式，对新追加的List分区下的子分区进行分区；
三、List-Range组合分区，全部表的数据实际存放在子分区所在的表空间。
附：
1、DROP TABLE
drop table LST_RNG_RANGE;
--并不是真删，而是置DROP标志，相关分区也依旧存在
select * from user_recyclebin;
实际清空
purge table LST_RNG_RANGE;
2、查看数据记录所在表空间
SELECT B.TABLESPACE_NAME
FROM DBA_DATA_FILES B
WHERE B.FILE_ID = (SELECTDBMS_ROWID.ROWID_RELATIVE_FNO(ROWID) FILE_ID
FROM LST_RNG_RANGE A
WHERE A.SALE_NO='SN201507260001');
3、经常使用分区表相关语句
--显示数据库全部分区表的信息：
select * from DBA_PART_TABLES;
--显示当前用户可訪问的全部分区表信息:
select * from ALL_PART_TABLES;
--显示当前用户全部分区表的信息：
select * from USER_PART_TABLES;
--显示表分区信息 显示数据库全部分区表的具体分区信息：
select * from DBA_TAB_PARTITIONS;
--显示当前用户可訪问的全部分区表的具体分区信息：
select * from ALL_TAB_PARTITIONS;
--显示当前用户全部分区表的具体分区信息：
select * from USER_TAB_PARTITIONS;
--显示子分区信息 显示数据库全部组合分区表的子分区信息：
select * from DBA_TAB_SUBPARTITIONS;
--显示当前用户可訪问的全部组合分区表的子分区信息：
select * from ALL_TAB_SUBPARTITIONS;
--显示当前用户全部组合分区表的子分区信息：
select * from USER_TAB_SUBPARTITIONS;
--显示分区列 显示数据库全部分区表的分区列信息：
select * from DBA_PART_KEY_COLUMNS;
--显示当前用户可訪问的全部分区表的分区列信息：
select * from ALL_PART_KEY_COLUMNS;
--显示当前用户全部分区表的分区列信息：
select * from USER_PART_KEY_COLUMNS;
--显示子分区列 显示数据库全部分区表的子分区列信息：
select * from DBA_SUBPART_KEY_COLUMNS;
--显示当前用户可訪问的全部分区表的子分区列信息：
select * from ALL_SUBPART_KEY_COLUMNS;
--显示当前用户全部分区表的子分区列信息：
select * from USER_SUBPART_KEY_COLUMNS;
--如何查询出oracle数据库中全部的的分区表
select * from user_tables a where a.partitioned='YES';
--删除一个表的数据是
truncate table table_name;
--删除分区表一个分区的数据是
alter table table_name truncate partition p5;
