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:\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;

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

(

AUTO_ID VARCHAR2(36) not null,

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),

constraint PK_LST_RNG_LISTprimary key (AUTO_ID)

)

partition by list

(POS_CODE)

subpartition by range

subpartition template (

subpartition SP_20150726

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';

watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQv/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center" alt="">

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

INSERT INTO LST_RNG_LIST(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_LIST(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);

INSERT INTO LST_RNG_LIST(AUTO_ID,SALE_NO,POS_CODE,POS_NAME,TOTAL_AMOUNT,SALE_DATE,REMARK)

VALUES(SYS_GUID(),'SN201508010001','3512860010','全味食品商贸有限公司','1132.23',TO_DATE('2015-08-01','YYYY-MM-DD'),NULL);

commit;

3.2.4、查看数据

查看分区数据

select * from LST_RNG_LIST partition(P_3512860010);

select * from LST_RNG_LIST partition(P_3512860005);

select * from LST_RNG_LIST subpartition(P_3512860010_SP_20150726);

select * from LST_RNG_LIST subpartition(P_3512834993_SP_20150802);

收集分区统计信息

begin

dbms_stats.gather_table_stats(ownname=>'WKOD_VERIFY',granularity =>'all',tabname=>'LST_RNG_LIST',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_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';

watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQv/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center" alt="">

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

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';

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')))

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_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';

watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQv/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center" alt="">

partition by list

(POS_CODE)

subpartition by range

(SALE_DATE)

subpartition template (

subpartition SP_20150726

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

)

(

partition

P_3512860010

values ('3512860010')

tablespace TS_3512860010,

partition
