MySQL分区相关sql语法

分区的sql语句：
 partition BY RANGE (store_id) (
    partition p0 VALUES LESS THAN (6),
    partition p1 VALUES LESS THAN (11),
    partition p2 VALUES LESS THAN (16),
    partition p3 VALUES LESS THAN (21),
    PARTITION p4 VALUES LESS THAN MAXVALUE
);
删除分区
alter table user drop partition p4;
新增分区
alter table user add partition(partition p4 values less than MAXVALUE);
