这是现实中的一个例子，但是我不推荐使用MySQL分区用于生产
CREATE TABLE `t_log` (
`ID` int(11) NOT NULL AUTO_INCREMENT COMMENT '主键ID',
`VERSON` int(11) NOT NULL DEFAULT 0 COMMENT ' 版本号',
`ACTIONS` varchar(100) DEFAULT NULL COMMENT ' 操作记录',
`ADMINID` int(11) DEFAULT 1 COMMENT '管理员ID',
`IP` varchar(20) DEFAULT '1' COMMENT ' 登录Ip',
`CDATE` datetime NOT NULL COMMENT '添加时间',
`UDATE` datetime NOT NULL COMMENT '修改时间',
PRIMARY KEY (`ID`,`CDATE`),
KEY `ADMINID` (`ADMINID`) USING BTREE
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT='日志表'
Time: 0.024s
ALTER TABLE `blog`.`t_log` PARTITION BY RANGE (year(`CDATE`))
PARTITIONS 1
SUBPARTITION BY HASH (to_days(`CDATE`))
SUBPARTITIONS 4
(PARTITION `p0` VALUES LESS THAN (2020)
(SUBPARTITION `s200` ,
SUBPARTITION `s201` ,
SUBPARTITION `s202` ,
SUBPARTITION `s203` ))
Time: 0.057s
alter table t_log
ADD PARTITION (PARTITION `p1` VALUES LESS THAN (2021)(
SUBPARTITION `s210` ENGINE = InnoDB,
SUBPARTITION `s211` ENGINE = InnoDB,
SUBPARTITION `s212` ENGINE = InnoDB,
SUBPARTITION `s213` ENGINE = InnoDB
))
