mysqldump auto_increment导致主键错误
作者：互联网
我正在使用mysqldump(a)转储表,然后(b)将其插入其他地方.当我尝试执行部分(b)时出现问题.这是我得到的错误.
密钥“ PRIMARY”的条目“ 1”重复
现在,等等,等等.我知道我不会插入重复的主键….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…..中指定的auto_increment值的任何行,则无论该ID是否重复,MySQL都会给出此错误.
我尝试从TABLE CREATE语句中手动删除AUTO_INCREMENT.同样的错误.
更新：这是Create table语句的一些相关部分.除去插入物,甚至其中之一也是巨大的：
/*!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`)

解决方法:
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).在MySQL 5.1.11中有一个known issue,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构造：
mysqldump -u username -p -h <db-host> --opt <db-name> -d --single-transaction | sed 's/ AUTO_INCREMENT=[0-9]*\b//' > <filename>.sql
