Je l'ai remarqué:

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`) 

Je pense que vous avez votre clé et les références ne correspondent pas.Cela peut ne pas résoudre votre problème entier, mais c'est encore quelque chose à corriger :). Faites-moi savoir si vos erreurs changent avec cette mise à jour.

Editer: J'ai trouvé autre chose.

Tel qu'indiqué sur MySQL Reference

InnoDB nécessite des index sur des clés étrangères et des clés référencées afin que les contrôles clés étrangers peuvent être rapide et ne nécessite pas une analyse de table. Dans la table de référence, il doit y avoir un index où les colonnes de clé étrangère sont répertoriées en tant que premières colonnes dans le même ordre. Un tel index est créé automatiquement sur la table de référence s'il n'existe pas. (Cela contraste avec certaines versions plus anciennes, dans lesquelles les index devaient être créés explicitement ou la création de contraintes de clé étrangère échouait). Index_name, s'il est donné, est utilisé comme décrit précédemment.

    `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) ,

Par ce texte de référence, les clés référencées doivent être dans le même ordre que sur le tableau référencé. Vous les avez dans un ordre différent de votre clé primaire.
