MySQL 5.5 range分区增加删除处理案例详细说明

+----+-------------+-------------------------------+------------+-------+---------------+---------+---------+------+-------+--------------------------+ ##删除分区 mysql> alter table baby_account_change_log drop partition p0; Query OK, 0 rows affected (0.01 sec)

二、增加分区

#错误提示删除存储最大值分区
mysql> alter table baby_account_change_log add partition(PARTITION p13 VALUES LESS THAN (unix_timestamp('2017-12-31 23:59:59')));
ERROR 1481 (HY000): MAXVALUE can only be used in last partition definition

#删除存储最大值分区
mysql> alter table baby_account_change_log drop partition p12;

##增加新的分区

mysql> alter table baby_account_change_log add partition(PARTITION p12 VALUES LESS THAN (unix_timestamp('2017-12-31 23:59:59')));
