錯誤1215無法添加外鍵約束數據類型匹配

不知道還有其他要檢查/做什麼。我確信外鍵的數據類型相匹配（CHAR（36）），我保證外鍵語句使用正確的語法錯誤1215無法添加外鍵約束數據類型匹配

運行此腳本，我得到錯誤1215

USE addm; 
CREATE TABLE `addm`.`notificationResource` (
`notificationId` CHAR(36) NOT NULL , 
`resourceId` CHAR(36) NOT NULL , 
PRIMARY KEY (`notificationId`, `resourceId`) , 
INDEX `fk_notificationResource_notification_idx` (`notificationId` ASC) , 
INDEX `fk_notificationResource_resource_idx` (`resourceId` ASC) , 
CONSTRAINT `fk_notificationResource_notification` 
FOREIGN KEY (`notificationId`) 
REFERENCES `addm`.`notification` (`id`) 
ON DELETE NO ACTION 
ON UPDATE NO ACTION, 
CONSTRAINT `fk_notificationResource_resource` 
FOREIGN KEY (`resourceId`) 
REFERENCES `addm`.`resource` (`resourceId`) 
ON DELETE NO ACTION 
ON UPDATE NO ACTION); 
commit;

父表：

`resourceName` varchar(255) DEFAULT NULL, 
`resourceData` longblob, 
PRIMARY KEY (`resourceId`),

我認爲column CHARACTER SET是不同的。 'id' char（36）CHARACTER SET latin1 NOT NULL， –

就是這樣。你可以讓它成爲答案，我會選擇它。 – Phox

我認爲列CHARACTER SET是不同的。 id char（36）CHARACTER SET latin1 NOT NULL 更改CHARACTER SET

再次感謝這一點。它正在處理另一個數據庫，並且從現在開始。 – Phox
