一、新建分区

ALTER TABLE user PARTITION BY RANGE(id) (
　　PARTITION p2507 VALUES LESS THAN (27156132),
　　PARTITION p2508 VALUES LESS THAN (27820952),
　　PARTITION p2509 VALUES LESS THAN (28560158),
　　PARTITION p2510 VALUES LESS THAN (29357983),
　　PARTITION p2511 VALUES LESS THAN (30131978),
　　PARTITION p2512 VALUES LESS THAN (30914331),
　　PARTITION pmax VALUES LESS THAN MAXVALUE
);

二、重组分区

ALTER TABLE user REORGANIZE PARTITION pmax into(
　　PARTITION p2602 VALUES LESS THAN (31615759),
　　PARTITION pmax VALUES LESS THAN MAXVALUE
);

三、删除分区
ALTER TABLEuser DROPPARTITION p2507;

四、恢复无分区表
 ALTER TABLE user REMOVE PARTITIONING;
