GBase 8c表设计（三）

典型的分区表定义如下：

--创建Range分区表

CREATE TABLE staffS_p1 (

staff_ID NUMBER(6) not null, FIRST_NAME VARCHAR2(20), LAST_NAME VARCHAR2(25), EMAIL VARCHAR2(25), PHONE_NUMBER VARCHAR2(20), HIRE_DATE DATE,

employment_ID VARCHAR2(10), SALARY NUMBER(8,2), COMMISSION_PCT NUMBER(4,2), MANAGER_ID NUMBER(6),

section_ID NUMBER(4)

)

PARTITION BY RANGE (HIRE_DATE) (

PARTITION HIRE_19950501 VALUES LESS THAN ('1995-05-01 00:00:00'), PARTITION HIRE_19950502 VALUES LESS THAN ('1995-05-02 00:00:00'), PARTITION HIRE_maxvalue VALUES LESS THAN (MAXVALUE)

);

--创建Interval分区表，初始两个分区，插入分区范围外的数据会自动新增分区CREATE TABLE sales

(prod_id NUMBER(6), cust_id NUMBER, time_id DATE, channel_id CHAR(1), promo_id NUMBER(6),

quantity_sold NUMBER(3), amount_sold NUMBER(10,2)

)

PARTITION BY RANGE (time_id) INTERVAL('1 day')

( PARTITION p1 VALUES LESS THAN ('2019-02-01 00:00:00'), PARTITION p2 VALUES LESS THAN ('2019-02-02 00:00:00')

);

--创建List分区表

CREATE TABLE test_list (col1 int, col2 int) partition by list(col1)

(

partition p1 values (2000), partition p2 values (3000), partition p3 values (4000), partition p4 values (5000)

);

--创建Hash分区表

CREATE TABLE test_hash (col1 int, col2 int) partition by hash(col1)

(

partition p1, partition p2

);
