錯誤ORA-02291：完整性約束 - 1：1而不是1：M？

我看到父鍵沒有找到。在我的情況下，FK_PLAYERTEAM和FK_PLAYERPOSITION。我注意到，無論我看到這個錯誤，它都是操作錯誤的順序。在播放器表格中輸入或引用這些值之前，未輸入位置值或團隊ID。在我看來，一旦有14名球員進入，相同數量的球隊進入，我不能再輸入更多的球員。錯誤ORA-02291：完整性約束 - 1：1而不是1：M？

那麼我在這裏有一對一而不是一對多的關係嗎？請檢閱我的作品！我是新來的，爲我暑期班的項目做這個。

你申請了不正確的外鍵約束，試試這個：

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

不客氣，@Itrysometimes – tibetty

您也可以將FK聲明爲列定義的一部分，並繼承數據類型：'city_id約束fk_teamcity引用city（id）' –
