Oracle-13：Oracle中的表分区

發布時間：2023/12/6 编程问答 24 豆豆

生活随笔收集整理的這篇文章主要介紹了 Oracle-13：Oracle中的表分区小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

------------吾亦無他,唯手熟爾，謙卑若愚，好學若饑-------------

本篇博客記錄了表分區

表分區的含義：

典型的拿空間換時間的案例！

表分區對一張表進行分區，分區之后表中的數據存在相對應的分區內（可以是不同物理存儲的位置），實際上他還是一張表！！！！！！！

表分區的好處：

均衡了IO（可以放在多個不同磁盤的位置）

提升了查詢性能（可以不必檢索所有記錄）

維護方便（假如數據出現問題，分區之后只需維護出現問題的那個分區）

增強了可用性（假如一個表分區掛掉了，其他分區可以繼續使用，而不是全掛掉）

表分區的缺點：

假如數據量太小，就無需使用表分區，否者浪費性能

提供數據庫腳本供測試使用：（合起來了，以免影響閱讀）

--創建表分區根據某一列（range）（用范圍限定，范圍分區）

概念：

表空間的創建：

操作代碼

create table TEACHER(tno NUMBER(4) not null,tname VARCHAR2(30) not null,tid CHAR(18),gendar CHAR(3),birthdate DATE,job VARCHAR2(20),hiredate DATE,sal NUMBER(7,2),deptno NUMBER(2),mgrno NUMBER(4),comm NUMBER(7,2))partition by range(tno)(partition part1 values less than(1030) tablespace partition1,partition part2 values less than(1080) tablespace partition2,partition part3 values less than(maxvalue) tablespace partition3);

查詢表分區

--查詢對應表分區下的數據

select * from teacher partition(part3)

--查詢所有表分區

select * from all_tab_partitions

--查詢子分區和分區（組合分區中用的）

select * from teacher partition(EMPLOYEE_DEPTNO_10)select * from teacher SUBPARTITION(EMPLOYEE_10_JOB_MAGAGER)

刪除表分區

--1.刪除表分區，包含分區中的所有數據

alter table teacher drop partition part1;--查一下有沒有select * from teacher partition(part1)select * from teacherselect * from all_tab_partitions--繼續刪alter table teacher drop partition part2;alter table teacher drop partition part3;--報錯，所以更換另外一種手段

--2.刪除表以及它的表分區，到回收站

drop table teacher purge;--查一下select * from all_tab_partitions

--3.清空回收站，以防止有同名表分區

purge table teacher

創建表分區，（list）根據列表（男或者女，中國省份這種定值）

操作：

create table TEACHER(tno NUMBER(4) not null,tname VARCHAR2(30) not null,tid CHAR(18),gendar CHAR(3),birthdate DATE,job VARCHAR2(20),hiredate DATE,sal NUMBER(7,2),deptno NUMBER(2),mgrno NUMBER(4),comm NUMBER(7,2))partition by list(gendar)(partition part1 values ('男') tablespace partition1,partition part2 values ('女') tablespace partition2);

創建分區（Hash），必須是2的n次方的分區數量

操作：

create table TEACHER(tno NUMBER(4) not null,tname VARCHAR2(30) not null,tid CHAR(18),gendar CHAR(3),birthdate DATE,job VARCHAR2(20),hiredate DATE,sal NUMBER(7,2),deptno NUMBER(2),mgrno NUMBER(4),comm NUMBER(7,2))partition by hash(tname)(partition part1 tablespace partition1,partition part2 tablespace partition2);

組合分區（）

可以使用上面三種中的任意倆種，或者任意一種使用倆次進行組合嵌套

對于同一張組合分區表而言，子分區的名字不能相同，即使不在相同的分區里！

操作：

create table TEACHER(tno NUMBER(4) not null,tname VARCHAR2(30) not null,tid CHAR(18),gendar CHAR(3),birthdate DATE,job VARCHAR2(20),hiredate DATE,sal NUMBER(7,2),deptno NUMBER(2),mgrno NUMBER(4),comm NUMBER(7,2))PARTITION BY LIST (DEPTNO)SUBPARTITION BY LIST (JOB)(PARTITION EMPLOYEE_DEPTNO_10 VALUES (10) TABLESPACE partition1( SUBPARTITION EMPLOYEE_10_JOB_MAGAGER VALUES ('考試專員'),SUBPARTITION EMPLOYEE_10_JOB_DEFAULT VALUES (DEFAULT)),PARTITION EMPLOYEE_DEPTNO_20 VALUES (20) TABLESPACE partition2( SUBPARTITION EMPLOYEE_20_JOB_MAGAGER VALUES ('考試專員'),SUBPARTITION EMPLOYEE_20_JOB_DEFAULT VALUES (DEFAULT)),PARTITION EMPLOYEE_DEPTNO_OTHERS VALUES (DEFAULT) TABLESPACE partition3( SUBPARTITION EMPLOYEE_30_JOB_MAGAGER VALUES ('考試專員'),SUBPARTITION EMPLOYEE_30_JOB_DEFAULT VALUES (DEFAULT)));

--查詢子分區和分區（組合分區中用的）

select * from teacher partition(EMPLOYEE_DEPTNO_10)select * from teacher SUBPARTITION(EMPLOYEE_10_JOB_MAGAGER)
