I am using mysqldump to (a) dump a table, then (b) insert it elsewhere. A problem occurs when I try to do part (b). Here is the error I get.

Duplicate entry ‘1’ for key ‘PRIMARY’

Now, hold on, hold on. I know I’m not inserting duplicate primary keys …. I checked the CREATE TABLE statement. The auto_incremement on the id field is left at the greatest value for the id column: AUTO_INCREMENT=45634650. I believe that the problem is that MySQL will give this error if you try to insert any row with an id value less than what the auto_increment value is specified at …. regardless if that id is a duplicate or not.

I tried manually removing the AUTO_INCREMENT from the TABLE CREATE statement. Same error still.

UPDATE: Here are some relevant parts of the Create table statement. Leaving out the inserts, even one of them is huge:

/*!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 */;

I ran into this very same issue a few months ago (posted solution on my blog). There is a known issue with MySQL 5.1.11+ where if you do a mysqldump, it also outputs the auto_increment count (as you stated in your post). You can use sed (stream edit) and parse out the auto_increment construct when generating your dump file:

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