错误ORA-02291：完整性约束 - 1：1而不是1：M？

我看到父键没有找到。在我的情况下，FK_PLAYERTEAM和FK_PLAYERPOSITION。我注意到，无论我看到这个错误，它都是操作错误的顺序。在播放器表格中输入或引用这些值之前，未输入位置值或团队ID。在我看来，一旦有14名球员进入，相同数量的球队进入，我不能再输入更多的球员。错误ORA-02291：完整性约束 - 1：1而不是1：M？

那么我在这里有一对一而不是一对多的关系吗？请检阅我的作品！我是新来的，为我暑期班的项目做这个。

但我结束了14日线后获得：

你申请了不正确的外键约束，试试这个：

CREATE TABLE TEAM (
    ID int     NOT NULL PRIMARY KEY, 
    NAME varchar2(255)  DEFAULT 'FREE AGENT', 
    SHORT_NAME varchar2(3) NOT NULL, 
    COACH_NAME varchar2(255) NULL, 
    CITY_ID int   NULL, 
    CONSTRAINT FK_TEAMCITY FOREIGN KEY (CITY_ID) REFERENCES CITY(ID) 
);

你是最好的朋友。 – Itrysometimes

不客气，@Itrysometimes – tibetty

您也可以将FK声明为列定义的一部分，并继承数据类型：'city_id约束fk_teamcity引用city（id）' –

错误ORA-02291：完整性约束 - 1：1而不是1：M？
