A quick thanks to anyone taking a look!

I have dev, stage and prod servers.

I created my database on dev, then did a mysqldump and installed the same database on stage and prod.

stage and prod are identical hardware, and os, which is latest LAMP stack.

When I insert a child row on prod, I get an error, yet it works on my dev and stage machines. That is weird. So ignoring that, here is my simple data (2 tables) and my error:

   CREATE TABLE `Customer` (
  `Customer_Id` int(11) unsigned NOT NULL AUTO_INCREMENT,
  `AccessLevel_Id` int(11) unsigned NOT NULL,
  `UserId` varchar(50) COLLATE utf8_unicode_ci NOT NULL,
  `FirstName` varchar(50) COLLATE utf8_unicode_ci NOT NULL,
  `LastName` varchar(50) COLLATE utf8_unicode_ci NOT NULL,
  `Phone` varchar(20) COLLATE utf8_unicode_ci NOT NULL,
  `Email` varchar(100) COLLATE utf8_unicode_ci NOT NULL,
  `Passwd` tinytext COLLATE utf8_unicode_ci NOT NULL,
  `HearAbout` varchar(50) COLLATE utf8_unicode_ci DEFAULT NULL,
  `Active` tinyint(1) NOT NULL DEFAULT '1',
  `Created` datetime NOT NULL,
  PRIMARY KEY (`Customer_Id`),
  UNIQUE KEY `UserId` (`UserId`),
  KEY `idxEmail` (`Email`),
  KEY `R8` (`AccessLevel_Id`),
  CONSTRAINT `R8` FOREIGN KEY (`AccessLevel_Id`) REFERENCES `accesslevel` (`AccessLevel_Id`) ON DELETE NO ACTION ON UPDATE NO ACTION
) ENGINE=InnoDB AUTO_INCREMENT=6 DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci |

CREATE TABLE `Recipient` (
  `Recipient_Id` int(11) unsigned NOT NULL AUTO_INCREMENT,
  `Customer_Id` int(11) unsigned NOT NULL,
  `FirstName` varchar(50) COLLATE utf8_unicode_ci DEFAULT NULL,
  `LastName` varchar(50) COLLATE utf8_unicode_ci DEFAULT NULL,
  `NickName` varchar(50) COLLATE utf8_unicode_ci DEFAULT NULL,
  `LastUsed` datetime DEFAULT NULL,
  `Active` tinyint(1) NOT NULL DEFAULT '1',
  `Created` datetime NOT NULL,
  PRIMARY KEY (`Recipient_Id`),
  KEY `R14` (`Customer_Id`),
  CONSTRAINT `R14` FOREIGN KEY (`Customer_Id`) REFERENCES `customer` (`Customer_Id`) ON DELETE CASCADE ON UPDATE CASCADE
) ENGINE=InnoDB AUTO_INCREMENT=10 DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci |

Here is the applicable id.

mysql> select * from Customer where Customer_Id=1;
+-------------+----------------+--------+-----------+----------+----------------+---------------------+------------------------------------+----------------+--------+---------------------+
| Customer_Id | AccessLevel_Id | UserId | FirstName | LastName | Phone          | Email               | Passwd                             | HearAbout      | Active | Created             |
+-------------+----------------+--------+-----------+----------+----------------+---------------------+------------------------------------+----------------+--------+---------------------+

+-------------+----------------+--------+-----------+----------+----------------+---------------------+------------------------------------+----------------+--------+---------------------+
1 row in set (0.00 sec)

Here is the constraint error: Can someone wiser than me, enlighten me? I'd really like to know what is causing this!!

mysql> INSERT INTO `Recipient` (`Customer_Id`, `NickName`, `FirstName`, `LastName`, `Created`) VALUES ('1', 'Moe', 'Moe', 'Howard', '2013-02-01 15:25:19');

OK、他の誰かがこの同じ問題に遭遇しましたが、今までここで見つけられませんでした: MySQL Foreign Key Error Even With Existent Referencesとこれにより、XAMPP でパッケージ化した MySQL の Mac バージョンを疑うようになりました。5.1.44です。ダンプ ファイルが正しく作成されないバグがあり、このエラーが発生します。

新しいバージョンの mySQL に切り替えると、問題が修正されました。
