Oracle 11gR2 List-Range分區實驗

一、實驗目的

採用List-Range分區，對主分區指定表空間或者對子分區指定表空的不同情況，測試如下內容：

1、對List主分區不指定表空間，對Range子分區指定表空間，數據實際存儲在哪個表空間；追加List主分區不指定Range子分區和指定Range子分區時，Oracle如何創建相關子分區；

2、對List主分區指定表空間，對Range子分區不指定表空間，數據實際存儲在哪個表空間；追加List主分區不指定Range子分區和指定Range子分區時，Oracle如何創建相關子分區；

二、實驗環境

操作系統：Window 7 旗艦版 x64

Cpu：Intel i5-2520M 2.50GHz X 2

內存：10G

Oracle版本：Release 11.2.0.1.0

三、List指定表空間測試

3.1、創建表空間

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、兩個List兩個Range測試

3.2.1、創建分區

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

3.2.2、查看分區

查看主分組

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

from user_tab_partitions

where table_name='LST_RNG_LIST';

查看子分區

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子分區所屬表空間自動歸入List分區所屬表空間

3.2.3、插入數據

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

VALUES(SYS_GUID(),'SN201507240001','3512860010','全味食品商貿有限公司','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','全味食品商貿有限公司','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(),'SN201507290001','3512860010','全味食品商貿有限公司','1132.23',TO_DATE('2015-07-29','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','全味食品商貿有限公司','1132.23',TO_DATE('2015-08-01','YYYY-MM-DD'),NULL);

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

3.2.4、查看數據

查看分區數據

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);

收集分區統計信息

begin

dbms_stats.gather_table_stats(ownname=>'WKOD_VERIFY',granularity =>'all',tabname=>'LST_RNG_LIST',cascade=>true);

end;

查看主分組

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表分別在兩個表空間中有5條數據

查看子分區

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、追加分區

方式一：追加主分區

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

查看分區

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

from user_tab_partitions

where table_name='LST_RNG_LIST';

查看子分區

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';

默認按照表創建時子分區的的分區規則，自動生成兩個子分區（紅色框內）

刪除添加的List分區

alter table LST_RNG_LIST drop partitionP_3512834993;

對應的子分區會自動被drop掉。

方式二：追加主分區及其子分區

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')))

查看分區

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

from user_tab_partitions

where table_name='LST_RNG_LIST';

查看子分區

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';

按照設定的子分區創建range子分區
