MySQL分区表维护（1）

添加分区

alter table t_partion_test     add PARTITION( PARTITION p_max values less than maxvalue) ;

 
 拆分区
ALTER TABLE t_partion_test REORGANIZE PARTITION p_max INTO (
PARTITION p6 VALUES LESS THAN (60000),
PARTITION p_max values less than maxvalue
);

用表交换分区
ALTER TABLE t_partion_test EXCHANGE PARTITION p6 WITH TABLE t_nopartion_test;

 

truncate分区
alter table t_partion_test TRUNCATE PARTITION p6 ;

 

删除分区

alter table t_partion_test drop PARTITION p0 ;
