mysqldump + auto_increment 导致主键错误

Question

我正在使用 mysqldump (a) 转储一个表，然后 (b) 将它插入到别处。当我尝试执行 (b) 部分时出现问题。这是我得到的错误。

键“PRIMARY”的重复条目“1”

现在，坚持，坚持。我知道我没有插入重复的主键....我检查了 CREATE TABLE 语句。 id 字段上的 auto_incremement 保留为 id 列的最大值:AUTO_INCREMENT=45634650。我认为问题在于，如果您尝试插入 id 值小于 auto_increment 指定值的任何行，MySQL 将给出此错误....无论该 id 是否重复。

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

更新:这里是创建表语句的一些相关部分。撇开插入，即使是其中一个也是巨大的:

/*!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 */;

几个月前我遇到了同样的问题(在我的 blog 上发布了解决方案)。有一个known issue对于 MySQL 5.1.11+，如果您执行 mysqldump，它还会输出 auto_increment 计数(如您在帖子中所述)。您可以使用 sed(流编辑)并在生成转储文件时解析出 auto_increment 结构:

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