MySql数据分区操作之新增分区操作(3)

INSERT INTO tr VALUES (11, 'pencil holder', '1995-07-12′);
ALTER TABLE tr DROP PARTITION p3;
SELECT * FROM tr WHERE purchased  BETWEEN '1995-01-01′ AND '2004-12-31′;

创建一个新的测试表

复制代码 代码如下:

CREATE TABLE members (
    id INT,
    fname VARCHAR(25),
    lname VARCHAR(25),
    dob DATE
)
PARTITION BY RANGE(YEAR(dob)) (
    PARTITION p0 VALUES LESS THAN (1970),
    PARTITION p1 VALUES LESS THAN (1980),
    PARTITION p2 VALUES LESS THAN (1990)
);

直接用alter table tablename add partition 方式再最后面添加分区

复制代码 代码如下:

ALTER TABLE members ADD PARTITION (PARTITION p3 VALUES LESS THAN (2000));

复制代码 代码如下:
