Getting error 1503: primary key must include all columns in table splitting function

I have a table structure, for example -

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

and when I create the section -

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));

having received

error 1503: A primary key must include all columns in the table partitioning function

I read everywhere about this, but get nothing, so let me know how to split this table. I have over 20 million entries.

Thanks.

I already solved this problem by adding eventdate with primary key.

Possible solutions:

  • change eventdate to eventDate in 'ALTER TABLE cdr PARTITION by RANGE (TO_DAYS (eventdate))'
  • change eventDate to timestamp. (mysql cannot make a partition in datetime)
