Oracle 11gR2 List-Range分区实验

一、实验目的

     采用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,测试如下内容:

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如何创建相关子分区;

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如何创建相关子分区;


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:Release 11.2.0.1.0


三、List指定表空间测试

3.1、创建表空间

CREATE TABLESPACE "TS_3512860010" DATAFILE 'D:\APP\ORADATA\ORCL\TS_3512860010.dbf' SIZE 50M AUTOEXTEND ON NEXT16K MAXSIZE UNLIMITED LOGGING EXTENT MANAGEMENT LOCAL SEGMENT SPACE MANAGEMENTAUTO;

CREATE TABLESPACE "TS_3512860005" DATAFILE 'D:\APP\ORADATA\ORCL\TS_3512860005.dbf' SIZE 50M AUTOEXTEND ON NEXT16K MAXSIZE UNLIMITED LOGGING EXTENT MANAGEMENT LOCAL SEGMENT SPACE MANAGEMENTAUTO;

CREATE TABLESPACE "TS_3512834993" DATAFILE 'D:\APP\ORADATA\ORCL\TS_3512834993.dbf' SIZE 50M AUTOEXTEND ON NEXT16K MAXSIZE UNLIMITED LOGGING EXTENT MANAGEMENT LOCAL SEGMENT SPACE MANAGEMENTAUTO;

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';

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';


Range子分区存放于指定的表空间中


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';


默认按照表创建时子分区的的分区规则,自动生成一个子分区(红色框内),且分区对应表空间与原来一致

 

删除添加的List分区

alter table LST_RNG_RANGE drop partition P_3512834993;

对应的子分区会自动被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';


按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自动将Range子分区存放于对应的List表空间中;

二、追加分区时候,在不指定子分区的情况下,Oracle默认按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,所有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;

--并非真删,而是置DROP标志,相关分区也依然存在

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、常用分区表相关语句

select * from DBA_PART_TABLES;


--显示当前用户可访问的所有分区表信息:
select * from ALL_PART_TABLES;

--怎样查询出oracle数据库中所有的的分区表
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
