我有一个表结构像 –
CREATE TABLE `cdr` (`id` bigint(20) NOT NULL AUTO_INCREMENT,
`dataPacketDownLink` bigint(20) DEFAULT NULL,
`dataPacketUpLink` bigint(20) DEFAULT NULL,
`dataPlanEndTime` datetime DEFAULT NULL,
`dataPlanStartTime` datetime DEFAULT NULL,
`dataVolumeDownLink` bigint(20) DEFAULT NULL,
`dataVolumeUpLink` bigint(20) DEFAULT NULL,
`dataplan` varchar(255) DEFAULT NULL,
`dataplanType` varchar(255) DEFAULT NULL,
`createdOn` datetime DEFAULT NULL,
`deviceName` varchar(500) DEFAULT NULL,
`duration` int(11) NOT NULL,
`effectiveDuration` int(11) NOT NULL,
`hour` int(11) DEFAULT NULL,
`eventDate` datetime DEFAULT NULL,
`msisdn` bigint(20) DEFAULT NULL,
`quarter` int(11) DEFAULT NULL,
`validDays` int(11) DEFAULT NULL,
`dataLeft` bigint(20) DEFAULT NULL,
`completedOn` datetime DEFAULT NULL,
PRIMARY KEY (`id`),
KEY `msisdn_index` (`msisdn`),
KEY `eventdate_index` (`eventDate`)
) ENGINE=MyISAM AUTO_INCREMENT=55925171 DEFAULT CHARSET=latin1
当我创建分区时 –
ALTER TABLE cdr PARTITION BY RANGE (TO_DAYS(eventdate)) (
PARTITION p01 VALUES LESS THAN (TO_DAYS('2013-09-01')),
PARTITION p02 VALUES LESS THAN (TO_DAYS('2013-09-15')),
PARTITION p03 VALUES LESS THAN (TO_DAYS('2013-09-30')),
PARTITION p04 VALUES LESS THAN (MAXVALUE));
得到了
error 1503: A primary key must include all columns in the table's partitioning function
我到处都读过这个但没有得到任何东西所以请告诉我如何分区这个表.我有2000万条记录.
谢谢.
最佳答案 我已经通过使用主键添加eventdate解决了这个问题.
