mysql partition table use to_days bug

to_days分区表 bug

CREATE TABLE `aaaaaaaaaa` (

  `id` int(255) NOT NULL AUTO_INCREMENT,

  `year` int(4) NOT NULL,

  `month` int(2) NOT NULL,

  `day` int(2) NOT NULL,

  `startTime` datetime NOT NULL,

  `endTime` datetime NOT NULL,

  `version` varchar(12) NOT NULL DEFAULT '',

  `source` varchar(12) NOT NULL DEFAULT '',

  `sid` varchar(12) NOT NULL,

  `valid` int(8) NOT NULL,

  `error` int(8) NOT NULL,

  `total` int(8) NOT NULL,

  PRIMARY KEY (`id`,`startTime`,`version`,`source`,`sid`),

  KEY `aaaaaaaaaa_index_startTime` (`startTime`),

  KEY `aaaaaaaaaa_index_endTime` (`endTime`),

  KEY `aaaaaaaaaa_muti_index` (`year`,`month`,`source`),

  KEY `aaaaaaaaaa_index_source` (`source`),

  KEY `month_index` (`month`),

  KEY `year_index` (`year`)

) ENGINE=InnoDB AUTO_INCREMENT=1267666446 DEFAULT CHARSET=utf8

/*!50100 PARTITION BY RANGE (to_days(startTime))

(PARTITION p20160405 VALUES LESS THAN (736425) ENGINE = InnoDB,

 PARTITION p20160620 VALUES LESS THAN (736501) ENGINE = InnoDB,

 PARTITION p20160706 VALUES LESS THAN (736517) ENGINE = InnoDB) */

 

 

  执行下面的sql，mysql 会crash

 select sid as sid,source as source,sum(valid) as valid,sum(error) as error from aaaaaaaaaa where startTime>="2016-07-08 10:00:00" 

 

  通过下面的方法可以fix

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

 

另：

CREATE TABLE `aaaaaaaaaa` (

  `id` int(255) NOT NULL AUTO_INCREMENT,

  `year` int(4) NOT NULL,

  `month` int(2) NOT NULL,

  `day` int(2) NOT NULL,

  `startTime` datetime NOT NULL,

  `endTime` datetime NOT NULL,

  `version` varchar(12) NOT NULL DEFAULT '',

  `source` varchar(12) NOT NULL DEFAULT '',

  `sid` varchar(12) NOT NULL,

  `valid` int(8) NOT NULL,

  `error` int(8) NOT NULL,

  `total` int(8) NOT NULL,

  PRIMARY KEY (`id`,`startTime`,`version`,`source`,`sid`)

  ) ENGINE=InnoDB AUTO_INCREMENT=1267666446 DEFAULT CHARSET=utf8

/*!50100 PARTITION BY RANGE (to_days(startTime))

(PARTITION p20160405 VALUES LESS THAN (736425) ENGINE = InnoDB,

 PARTITION p20160620 VALUES LESS THAN (736501) ENGINE = InnoDB,

 PARTITION p20160706 VALUES LESS THAN (736517) ENGINE = InnoDB) */

 

 这样不会出现上面的问题

 

 

 

 但如果把starttime列加上索引 ，就会有这个问题

 CREATE TABLE `aaaaaaaaaa` (

  `id` int(255) NOT NULL AUTO_INCREMENT,

  `year` int(4) NOT NULL,

  `month` int(2) NOT NULL,

  `day` int(2) NOT NULL,

  `startTime` datetime NOT NULL,

  `endTime` datetime NOT NULL,

  `version` varchar(12) NOT NULL DEFAULT '',

  `source` varchar(12) NOT NULL DEFAULT '',

  `sid` varchar(12) NOT NULL,

  `valid` int(8) NOT NULL,

  `error` int(8) NOT NULL,

  `total` int(8) NOT NULL,

  PRIMARY KEY (`id`,`startTime`,`version`,`source`,`sid`),

  KEY `aaaaaaaaaa_index_startTime` (`startTime`)

) ENGINE=InnoDB AUTO_INCREMENT=1267666446 DEFAULT CHARSET=utf8

/*!50100 PARTITION BY RANGE (to_days(startTime))

(PARTITION p20160405 VALUES LESS THAN (736425) ENGINE = InnoDB,

 PARTITION p20160620 VALUES LESS THAN (736501) ENGINE = InnoDB,

 PARTITION p20160706 VALUES LESS THAN (736517) ENGINE = InnoDB) */
