我有一个像这样的表结构:
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
error 1503: A primary key must include all columns in the table's partitioning function

我到处都读到了这个,但是什么也没得到,所以请让我知道如何对这张表进行分区。我有20+百万条记录。
谢谢。
