即使存在引用的MySQL外鍵錯誤

Question

在發佈之前，我已經完成了一些關於此問題的搜索。 這裏是問題：

mysql> insert into Buyer values (5594, CURDATE(), 490, 4830); 
ERROR 1452 (23000): Cannot add or update a child row: a foreign key constraint fails (`oppminer`.`buyer`, CONSTRAINT `FK3D9119337C53076` FOREIGN KEY (`office_id`) REFERENCES `Office` (`id`)) 

我證實，所引用的行存在：

mysql> select * from Office where id = 490; 
+-----+-----------+-----------+-------------+-------------------+ 
| id | name  | agency_id | location_id | primaryContact_id | 
+-----+-----------+-----------+-------------+-------------------+ 
| 490 | Top Level |  88 |  7363 |    451 | 
+-----+-----------+-----------+-------------+-------------------+ 
1 row in set (0.00 sec) 

下面是表描述：

| Buyer | CREATE TABLE `Buyer` (
    `id` int(11) NOT NULL AUTO_INCREMENT, 
    `created` datetime DEFAULT NULL, 
    `office_id` bigint(20) DEFAULT NULL, 
    `primaryContact_id` bigint(20) DEFAULT NULL, 
    PRIMARY KEY (`id`), 
    KEY `FK3D9119337C53076` (`office_id`), 
    KEY `FK3D911938ADC7080` (`primaryContact_id`), 
    CONSTRAINT `FK3D911938ADC7080` FOREIGN KEY (`primaryContact_id`) REFERENCES `Contact` (`id`), 
    CONSTRAINT `FK3D9119337C53076` FOREIGN KEY (`office_id`) REFERENCES `Office` (`id`) 
) ENGINE=InnoDB AUTO_INCREMENT=5595 DEFAULT CHARSET=latin1 | 
+------- 

| Office | CREATE TABLE `Office` (
    `id` bigint(20) NOT NULL AUTO_INCREMENT, 
    `name` varchar(255) DEFAULT NULL, 
    `agency_id` bigint(20) DEFAULT NULL, 
    `location_id` int(11) DEFAULT NULL, 
    `primaryContact_id` bigint(20) DEFAULT NULL, 
    PRIMARY KEY (`id`), 
    KEY `FK8C9C2ADC3FBD3FD6` (`agency_id`), 
    KEY `FK8C9C2ADCFF56D2BF` (`location_id`), 
    KEY `FK8C9C2ADC8ADC7080` (`primaryContact_id`), 
    CONSTRAINT `FK8C9C2ADC8ADC7080` FOREIGN KEY (`primaryContact_id`) REFERENCES `Contact` (`id`), 
    CONSTRAINT `FK8C9C2ADC3FBD3FD6` FOREIGN KEY (`agency_id`) REFERENCES `Agency` (`id`), 
    CONSTRAINT `FK8C9C2ADCFF56D2BF` FOREIGN KEY (`location_id`) REFERENCES `Location` (`id`) 
) ENGINE=InnoDB AUTO_INCREMENT=491 DEFAULT CHARSET=latin1 | 
+-------- 

我還調查表中的索引：

------------------------ 
LATEST FOREIGN KEY ERROR

Foreign key constraint fails for table `oppminer`.`buyer`: 

    CONSTRAINT `FK3D911938ADC7080` FOREIGN KEY (`primaryContact_id`) REFERENCES `Contact` (`id`) 
Trying to add to index `FK3D911938ADC7080` tuple: 
DATA TUPLE: 2 fields; 
0: len 8; hex 80000000000012de; asc   ;; 
1: len 4; hex 800015da; asc  ;; 

But the parent table `oppminer`.`Contact` 
or its .ibd file does not currently exist! 

我有兩臺機器，我恢復了相同的轉儲。在工作機器上，我可以成功地執行相同的命令，從而在有問題的機器上導致錯誤。 任何想法，堆棧溢出？

它也被固定在最近發佈（5月31日）的MySQL 5.5.13：
