案例错误正在修复，我已经多次掺杂并创建了模式，但仍然无法正常工作。 – 2010-09-21 04:06:05

我注意到了这一点：


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`)

我觉得你有你的钥匙和引用不匹配。这可能无法解决你的整个问题，但它仍然是一个需要修正的问题:)。让我知道如果您的错误随着更新而改变。

编辑：我发现了别的东西。

上MySQL Reference

上市的InnoDB需要对外键和被引用键的索引以便外键检查可以快速，不需要表扫描。在引用表中，必须有一个索引，其中外键列以相同顺序排列为第一列。如果索引表不存在，则会在引用表上自动创建这样的索引。（这与一些较早的版本形成对比，在这些版本中索引必须明确创建，否则外键约束的创建将失败。）如前所述，使用index_name（如果已给定）。


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;

根据该引用文本，引用的键需要与引用的表中的顺序相同。您拥有的顺序与您的主键不同。

我刚刚尝试更改不匹配的引用，但没有任何更改仍然是相同的问题，感谢您看它！ – 2010-09-21 13:11:16

我刚刚用我发现的另一件事更新了我的解决方案。我不知道你是否仍然试图做到这一点，但可能会有所帮助。 – Banana 2010-09-21 23:16:49

非常感谢你的工作 – 2010-09-25 19:06:55
