Answer 1

我认为这个问题是varchar2()缺少的长度：

CREATE TABLE Representatives (
    ID NUMBER(4) NOT NULL PRIMARY KEY,
    State CHAR(2) NOT NULL,
    District NUMBER NOT NULL CHECK(District>=1 AND District<=30),
    Party VARCHAR2(30),
    LastName VARCHAR2(20),
    Firstname VARCHAR2(20),
    StartOfTerm DATE,
    EndOfTerm DATE,
    SenRank VARCHAR2(255) CHECK (senRank IN ('junior', 'senior')),
    -----------------^
    Gender CHAR(1) CHECK (Gender IN ('M', 'F')),
    Birthdate DATE,
    FOREIGN KEY (State) REFERENCES States(State),
    FOREIGN KEY (Party) REFERENCES Parties(Party)
);

Here是db <>小提琴，没有外键声明。

Answer 2

SenRank VARCHAR2 CHECK（senRank IN（'junior'，'senior'）），

您忘记在VARCHAR2列中提及SenRank数据类型的长度。添加适当的长度，它应该可以正常工作：

SenRank VARCHAR2(25) CHECK(senRank IN ('junior', 'senior'))
