Thank you guys. Here are the tables: CREATE TABLE IF NOT EXISTS `WhichMovie`.`UserComent` ( `IDComent` INT NOT NULL, `IDUser` INT NOT NULL, `IDMovie` INT NOT NULL, `date` TIMESTAMP NOT NULL, PRIMARY KEY (`IDComent`, `IDUser`, `IDMovie`, `date`), INDEX `idUser_idx` (`IDUser` ASC), INDEX `idMovie_idx` (`IDMovie` ASC), CONSTRAINT `IdComent` FOREIGN KEY (`IDComent`) REFERENCES `WhichMovie`.`Coment` (`idComent`) ON DELETE CASCADE ON UPDATE CASCADE, CONSTRAINT `IiUser` FOREIGN KEY (`IDUser`) REFERENCES `WhichMovie`.`User` (`idUser`) ON DELETE CASCADE ON UPDATE CASCADE, CONSTRAINT `IdMovie` FOREIGN KEY (`IDMovie`) REFERENCES `WhichMovie`.`Movie` (`idMovie`) ON DELETE CASCADE ON UPDATE CASCADE) ENGINE = InnoDB; -- ----------------------------------------------------- -- Table `WhichMovie`.`Movie` -- ----------------------------------------------------- CREATE TABLE IF NOT EXISTS `WhichMovie`.`Movie` ( `idMovie` INT NOT NULL AUTO_INCREMENT, `Ttle` VARCHAR(45) NULL, `Year` INT NULL, `Country` VARCHAR(45) NULL, `Poster` BLOB NULL, `Rating` DECIMAL NULL, PRIMARY KEY (`idMovie`)) ENGINE = InnoDB; -- ----------------------------------------------------- -- Table `WhichMovie`.`User` -- ----------------------------------------------------- CREATE TABLE IF NOT EXISTS `WhichMovie`.`User` ( `idUser` INT NOT NULL AUTO_INCREMENT, `Username` VARCHAR(45) NOT NULL, `E

No comments · Posted by admin in MySQL MySQL CREATE TABLE statement throws error code 1022 with following message: "Error Code: 1022 Can't write; duplicate key in table [ Your table name ]". To error 1022 solve this please ensure you have unique key name assigned across indexes and foreign key names. So if you have Person, Address and PersonAddress tables with foreign keys associated with Address table. Then define unique values for index keys and foreign keys. Person table -> AddressId [ FK ] -> Address Table [ PK ] so error 1022 can't name address id to "fk_addressid_address" PersonAddress table -> AddressId [ FK ], PersonID [ FK] so name address id to "fk_addressid_person" and name person id to "fk_personid_person". As you can see now FK addressid named uniquely across your tables. This will resolve mysql error code 1022 issue. No tags No comments yet. Leave a Reply Click here to cancel reply.
