MYSQL的分区字段，必须包含在主键字段内

在对表进行分区时，如果分区字段没有包含在主键字段内，如表A的主键为ID,分区字段为createtime ，按时间范围分区，代码如下：  www.2cto.com  

CREATE TABLE T1 (

     id int(8) NOT NULL AUTO_INCREMENT,

     createtime datetime NOT NULL,

      PRIMARY KEY (id)

) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8

PARTITION BY RANGE(TO_DAYS (createtime))

(

PARTITION p0 VALUES LESS THAN (TO_DAYS('2010-04-15')),

PARTITION p1 VALUES LESS THAN (TO_DAYS('2010-05-01')),

PARTITION p2 VALUES LESS THAN (TO_DAYS('2010-05-15')),

PARTITION p3 VALUES LESS THAN (TO_DAYS('2010-05-31')),

PARTITION p4 VALUES LESS THAN (TO_DAYS('2010-06-15')),

PARTITION p19 VALUES LESS ThAN  MAXVALUE);

错误提示：#1503
