mysqldump + auto_increment导致主键错误

标签： mysql primary-key mysqldump auto-increment duplicates

我使用mysqldump来（a）转储表，然后（b）将其插入其他地方。当我尝试做（）部分时出现问题。这是我得到的错误。

键'PRIMARY'重复输入'1'

现在，坚持，坚持下去。我知道我没有插入重复的主键....我检查了CREATE TABLE语句。 id字段的auto_incremement保留为id列的最大值：AUTO_INCREMENT = 45634650。我相信问题是，如果你试图插入id值小于auto_increment值指定的任何行，那么MySQL会给出这个错误....无论该id是否重复。

我尝试从TABLE CREATE语句中手动删除AUTO_INCREMENT。同样的错误。

更新：以下是Create table语句的一些相关部分。离开插件，即使其中一个是巨大的：

/*!40014 SET @OLD_UNIQUE_CHECKS=@@UNIQUE_CHECKS, UNIQUE_CHECKS=0 */;
/*!40101 SET @OLD_SQL_MODE=@@SQL_MODE, SQL_MODE='NO_AUTO_VALUE_ON_ZERO' */;
/*!40111 SET @OLD_SQL_NOTES=@@SQL_NOTES, SQL_NOTES=0 */;
/*Table structure for table `WC_ip` */

DROP TABLE IF EXISTS `WC_ip`;

CREATE TABLE `WC_ip` (
  `id` int(11) NOT NULL AUTO_INCREMENT,

etc etc .. =)

  `activity_date` date DEFAULT NULL,
  UNIQUE KEY `userid_game_installAge` (`userid`,`game`,`install_age`),
  PRIMARY KEY (`id`)
) ENGINE=MyISAM AUTO_INCREMENT=45750081 DEFAULT CHARSET=latin1;

/*!40101 SET SQL_MODE=@OLD_SQL_MODE */;
/*!40014 SET UNIQUE_CHECKS=@OLD_UNIQUE_CHECKS */;
/*!40111 SET SQL_NOTES=@OLD_SQL_NOTES */;

答案 0 :(得分：4)

几个月前我遇到了同样的问题（在blog上发布了解决方案）。有一个known issue与MySQL 5.1.11+，如果你做一个mysqldump，它也输出auto_increment计数（如你在帖子中所述）。您可以使用sed（流编辑）并在生成转储文件时解析auto_increment构造：

mysqldump -u username -p -h <db-host> --opt <db-name> -d --single-transaction | sed 's/ AUTO_INCREMENT=[0-9]*\b//' > <filename>.sql

答案 1 :(得分：0)

auto_increment值是设置为NULL还是特定数字（如果它们为NULL），它们将使用表定义指定的下一个值。如果它们被明确表达，那么除非存在重复，否则它们应作为该值插入？

答案 2 :(得分：0)

我希望这可以帮到你

ALTER TABLE table2 AUTO_INCREMENT = 1;

或删除table2上的主键并找到相同的记录。
