Oracle 11gR2 List-Range分区实验

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

三、List指定表空间測试

3.1、创建表空间

CREATE TABLESPACE "TS_3512860010" DATAFILE 'D:APPORADATAORCLTS_3512860010.dbf' SIZE 50M AUTOEXTEND ON NEXT16K MAXSIZE UNLIMITED LOGGING EXTENT MANAGEMENT LOCAL SEGMENT SPACE MANAGEMENTAUTO;

CREATE TABLESPACE "TS_3512860005" DATAFILE 'D:APPORADATAORCLTS_3512860005.dbf' SIZE 50M AUTOEXTEND ON NEXT16K MAXSIZE UNLIMITED LOGGING EXTENT MANAGEMENT LOCAL SEGMENT SPACE MANAGEMENTAUTO;

CREATE TABLESPACE "TS_3512834993" DATAFILE 'D:APPORADATAORCLTS_3512834993.dbf' SIZE 50M AUTOEXTEND ON NEXT16K MAXSIZE UNLIMITED LOGGING EXTENT MANAGEMENT LOCAL SEGMENT SPACE MANAGEMENTAUTO;

3.2、两个List两个Range測试

3.2.1、 创建分区

drop table LST_RNG_LIST cascade constraints;

/*==============================================================*/

/* Table: LST_RNG_LIST                                        */

/*==============================================================*/

create table LST_RNG_LIST

   SALE_NO            VARCHAR2(36)         not null,

   POS_CODE           VARCHAR2(10),

   POS_NAME           VARCHAR2(30),

   TOTAL_AMOUNT        NUMBER(18,2),

   SALE_DATE           DATE,

   REMARK             VARCHAR2(500),

           values less than (TO_DATE('2015-07-26','YYYY-MM-DD')),

           subpartition SP_20150802

           values less than (TO_DATE('2015-08-02','YYYY-MM-DD'))

       )

    (

       partition

3.2.2、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_LIST';

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_LIST';

Range子分区所属表空间自己主动归入List分区所属表空间

3.2.3、插入数据

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_LIST';

num_rows=5，LST_PNG_LIST表分别在两个表空间中有5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_LIST';

3.2.5、追加分区

方式一：追加主分区

alter table LST_RNG_LIST add partitionP_3512834993 values ('3512834993') tablespace TS_3512834993

查看分区

select partition_position,table_name,partition_name,high_value,tablespace_name,num_rows

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_LIST';

默认依照表创建时子分区的的分区规则，自己主动生成两个子分区（红色框内）

删除加入的List分区

alter table LST_RNG_LIST drop partitionP_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_LIST add partition P_3512834993 values ('3512834993') tablespace TS_3512834993

(subpartition P_3512834993_SP_20150726 values less than (TO_DATE('2015-07-26','YYYY-MM-DD')))

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

4.3、两个List一个Range測试

drop table LST_RNG_RANGE cascade constraints;

/*==============================================================*/

/* Table:LST_RNG_RANGE                                        */

/*==============================================================*/

create table LST_RNG_RANGE 

(

  AUTO_ID             VARCHAR2(36)         not null,

  SALE_NO             VARCHAR2(36)         not null,

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;
