范围分区表是通过 create table 语句的 partition by range 子句来创建的,分区的范围通过 values less than 子句指定,其指定的是分区的上限(不包含),所有大于等于指定值的数据被分配至下一个分区,除了第一个分区,每个分区的下限即前一个分区的上限: create table members ( id number, name varchar2(32), creat...

在Oracle中,可以使用ALTER TABLE语句给已有的表建立分区。下面是一个示例: -- 创建一个新的分区表 CREATE TABLE my_table ( id INT, name VARCHAR2(50), date_created DATE ) PARTITION BY RANGE (date_created) ( PARTITION p1 VALUES LESS THAN (TO_DATE('01-01-2022', 'DD-MM-YYYY')), PARTITION...
在Oracle中创建分区表的方法是使用CREATE TABLE语句并在表定义中指定分区关键字。以下是一个示例: ``` CREATE TABLE employees ( employee_id NUMBER, employee_name VARCHAR2(50), hire_date DATE ) PARTITION BY RANGE (hire_date) ( PARTITION p1 VALUES LESS THAN (TO_DATE('01-JAN-2010', 'DD-MON-...
partition p0 values (default) ); 哈希分区: create table emp ( empno number(4), ename varchar2(30), sal number) partition by hash (empno) partitions 8 store in (emp1,emp2,emp3,emp4,emp5,emp6,emp7,emp8); 组合分区: 范围哈希组合分区: ...
