SET SQL_MODE=@OLD_SQL_MODE;

War es hilfreich?

Lösung

Ich bemerkte dies: 


CREATE  TABLE IF NOT EXISTS `mydb`.`MATCHES` (
  `idMatch` INT NOT NULL ,
  `idChampionship` INT NOT NULL ,
  `idTeam` INT NOT NULL ,
  `date` TIMESTAMP NULL DEFAULT NULL ,
  `gols` INT NULL DEFAULT -1 ,
  `isLocal` CHAR NULL DEFAULT 'N' ,
  PRIMARY KEY (`idMatch`, `idChampionship`, `idTeam`) ,
  INDEX `ID_TEAM_X_CHAMP` (`idChampionship` ASC, `idMatch` ASC) ,
  CONSTRAINT `ID_TEAM_X_CHAMP`
    FOREIGN KEY (`idChampionship` , `idMatch` )
    REFERENCES `mydb`.`TEAMS_PER_CHAMPIONSHIP` (`idChampionship` , `idTeam` )
    ON DELETE NO ACTION
    ON UPDATE NO ACTION)
ENGINE = InnoDB;


    FOREIGN KEY (`idChampionship` , `idMatch` )
    REFERENCES `mydb`.`TEAMS_PER_CHAMPIONSHIP` (`idChampionship` , `idTeam` )

Ich glaube, Sie haben Ihren Schlüssel und Referenzen stimmen nicht überein. Dies kann Ihr gesamtes Problem nicht lösen, aber es ist noch etwas fixiert :) werden. Lassen Sie uns wissen, wenn Ihr Fehler mit diesem Update ändern.

Edit:. Fand ich etwas anderes

Wie aufgelistet auf MySQL Reference

InnoDB Indizes für Fremdschlüssel und referenzierten Schlüssel erfordert, so dass Fremdschlüsselprüfungen schnell sein kann und nicht einen Tabellenscan erfordern. In der verweisende Tabelle, muss es einen Index, wo die Fremdschlüsselspalten als die ersten Spalten in derselben Reihenfolge aufgeführt sind. Ein solcher Index wird automatisch auf der verweisenden Tabelle erstellt, wenn sie noch nicht existiert. (Dies ist im Gegensatz zu einigen älteren Versionen, in denen Indizes hatte explizit erstellt werden oder die Schaffung von Fremdschlüsselbeschränkungen scheitern würde.) Index_name, falls angegeben, verwendet wird, wie zuvor beschrieben wird. 

CREATE  TABLE IF NOT EXISTS `mydb`.`TEAMS_PER_CHAMPIONSHIP` (
  `idTeam` INT NOT NULL ,
  `idChampionship` INT NOT NULL ,
  PRIMARY KEY (`idTeam`, `idChampionship`) ,
  INDEX `ID_TEAM` (`idTeam` ASC) ,
  INDEX `ID_CHAMP` (`idChampionship` ASC) ,
  CONSTRAINT `ID_TEAM`
    FOREIGN KEY (`idTeam` )
    REFERENCES `mydb`.`TEAMS` (`idTeam` )
    ON DELETE NO ACTION
    ON UPDATE NO ACTION,
  CONSTRAINT `ID_CHAMP`
    FOREIGN KEY (`idChampionship` )
    REFERENCES `mydb`.`CHAMPIONSHIPS` (`idChampionship` )
    ON DELETE NO ACTION
    ON UPDATE NO ACTION)
ENGINE = InnoDB;

CREATE  TABLE IF NOT EXISTS `mydb`.`MATCHES` (
  `idMatch` INT NOT NULL ,
  `idChampionship` INT NOT NULL ,
  `idTeam` INT NOT NULL ,
  `date` TIMESTAMP NULL DEFAULT NULL ,
  `gols` INT NULL DEFAULT -1 ,
  `isLocal` CHAR NULL DEFAULT 'N' ,
  PRIMARY KEY (`idMatch`, `idChampionship`, `idTeam`) ,
  INDEX `ID_TEAM_X_CHAMP` (`idChampionship` ASC, `idMatch` ASC) ,
  CONSTRAINT `ID_TEAM_X_CHAMP`
    FOREIGN KEY (`idChampionship` , `idMatch` )
    REFERENCES `mydb`.`TEAMS_PER_CHAMPIONSHIP` (`idChampionship` , `idTeam` )
    ON DELETE NO ACTION
    ON UPDATE NO ACTION)
ENGINE = InnoDB;

Per diesem Referenztext, müssen die referenzierten Schlüssel in der gleichen Reihenfolge wie auf den eingereichten verwiesen wird. Sie haben sie in einer anderen Reihenfolge als der Primärschlüssel.
