ここに見られるように、私は以下の既存のテーブルを持っています。
show create table ExpeditedAddress;
CREATE TABLE `expeditedaddress` (
`id` bigint(20) NOT NULL AUTO_INCREMENT,
`description` varchar(255) NOT NULL,
`address` varchar(255) NOT NULL,
`city` varchar(255) NOT NULL,
`country` varchar(255) NOT NULL,
`stateProvince` varchar(255) NOT NULL,
`zipPostal` varchar(255) NOT NULL,
`brokerageId` bigint(20) NOT NULL,
`timezoneCode` varchar(100) NOT NULL,
`productionFacilityId` bigint(20) NOT NULL,
`deliveryCutoffTime` time NOT NULL,
`deliveredByTime` time NOT NULL,
`daysToDeliver` int(11) NOT NULL,
PRIMARY KEY (`id`),
KEY `FK_ExpeditedAddress_Brokerage_ID` (`brokerageId`),
KEY `FK_ExpeditedAddress_Country_StateProvince` (`country`,`stateProvince`),
CONSTRAINT `ExpeditedAddress_ibfk_1` FOREIGN KEY (`brokerageId`) REFERENCES `brokerage` (`id`),
CONSTRAINT `ExpeditedAddress_ibfk_2` FOREIGN KEY (`country`, `stateProvince`) REFERENCES `stateprovince` (`countryName`, `name`)
) ENGINE=InnoDB AUTO_INCREMENT=149 DEFAULT CHARSET=utf8;
このテーブルを参照します
show create table ProductionFacility;
CREATE TABLE `productionfacility` (
`id` bigint(20) NOT NULL AUTO_INCREMENT,
`description` varchar(255) NOT NULL,
`address` varchar(255) NOT NULL,
`city` varchar(255) NOT NULL,
`country` varchar(255) NOT NULL,
`stateProvince` varchar(255) NOT NULL,
`zipPostal` varchar(255) NOT NULL,
`timezoneCode` varchar(100) NOT NULL,
`workingWeek` varchar(255) NOT NULL,
PRIMARY KEY (`id`),
KEY `FK_ProductionFacility_Country_StateProvince` (`country`,`stateProvince`),
CONSTRAINT `productionfacility_ibfk_1` FOREIGN KEY (`country`, `stateProvince`) REFERENCES `stateprovince` (`countryName`, `name`)
) ENGINE=InnoDB AUTO_INCREMENT=8 DEFAULT CHARSET=utf8;
次に、このように外部キーを追加しようとすると...
alter table ExpeditedAddress add foreign key FK_ExpeditedAddress_Productionfacility(productionFacilityId) references ProductionFacility(id);
私は次のようになります...
[2012-08-09 15:39:22] [42S01][1050] Table '.\realtorprint_dev_prod\expeditedaddress' already exists
[2012-08-09 15:39:22] [HY000][1025] Error on rename of '.\realtorprint_dev_prod\#sql-1d74_710a' to '.\realtorprint_dev_prod\expeditedaddress' (errno: -1)
[2012-08-09 15:39:22] [42S01][1050] Table '.\realtorprint_dev_prod\expeditedaddress' already exists
取得するのは非常に奇妙なエラーのようです。列のタイプは両方とも「bigint（20）notnull」です。どちらのテーブルもInnoDBです。参照される列は主キーです。
誰かアイデアはありますか？
また、これが実行の結果です
