问个 关于分区的问题...
SQL code
CREATE TABLE `tushumulu` (
  `id` int(11) NOT NULL,      //想设置为自动增涨的
  `isbn` int(11) NOT NULL,         //这个字段值会重复的
  `juan` varchar(30) NOT NULL,     //这个字段值会重复的
  `zhangjie` varchar(60) NOT NULL, //这个字段值会重复的
  `yeshu` varchar(100) NOT NULL, //这个字段值会重复的
  `contents` varchar(200) NOT NULL, //这个字段值会重复的
  `zishu` int(5) NOT NULL,
  `gengxinshijian` datetime NOT NULL //这个不会
) ENGINE=InnoDB DEFAULT CHARSET=utf8
PARTITION BY RANGE (isbn)
(PARTITION p0 VALUES LESS THAN (1100) ENGINE = InnoDB,
 PARTITION p1 VALUES LESS THAN (1200) ENGINE = InnoDB,
 PARTITION p2 VALUES LESS THAN (1300) ENGINE = InnoDB,
 PARTITION p3 VALUES LESS THAN (1400) ENGINE = InnoDB,
 PARTITION p4 VALUES LESS THAN (1500) ENGINE = InnoDB,
 PARTITION p5 VALUES LESS THAN (1600) ENGINE = InnoDB,
 PARTITION p6 VALUES LESS THAN (1700) ENGINE = InnoDB,
 PARTITION p7 VALUES LESS THAN (1800) ENGINE = InnoDB,
 PARTITION p8 VALUES LESS THAN (1900) ENGINE = InnoDB,
 PARTITION p9 VALUES LESS THAN (2000) ENGINE = InnoDB
 )


我想把 id 字段设置为 自动增加的 可是会报错. 要怎么解决呢?
#1503 - A PRIMARY KEY must include all columns in the table's partitioning function.



------解决方案--------------------
改为如下即可
SQL code
mysql> CREATE TABLE `tushumulu` (
    ->   `isbn` int(11) NOT NULL primary key,
    ->   `juan` varchar(30) NOT NULL,
    ->   `zhangjie` varchar(60) NOT NULL,
    ->   `yeshu` varchar(100) NOT NULL,
    ->   `contents` varchar(200) NOT NULL,
    ->   `zishu` int(5) NOT NULL,
    ->   `gengxinshijian` datetime NOT NULL
    -> ) ENGINE=InnoDB
    -> PARTITION BY RANGE (isbn)
    -> (PARTITION p0 VALUES LESS THAN (1100) ENGINE = InnoDB,
    ->  PARTITION p1 VALUES LESS THAN (1200) ENGINE = InnoDB,
    ->  PARTITION p2 VALUES LESS THAN (1300) ENGINE = InnoDB,
    ->  PARTITION p3 VALUES LESS THAN (1400) ENGINE = InnoDB,
    ->  PARTITION p4 VALUES LESS THAN (1500) ENGINE = InnoDB,
    ->  PARTITION p5 VALUES LESS THAN (1600) ENGINE = InnoDB,
    ->  PARTITION p6 VALUES LESS THAN (1700) ENGINE = InnoDB,
    ->  PARTITION p7 VALUES LESS THAN (1800) ENGINE = InnoDB,
    ->  PARTITION p8 VALUES LESS THAN (1900) ENGINE = InnoDB,
    ->  PARTITION p9 VALUES LESS THAN (2000) ENGINE = InnoDB
    ->  );
Query OK, 0 rows affected (1.25 sec)
