MySQL子分区一例
作者：互联网
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 )) Time: 0.054s
