是什么导致了我的错误？

Answer 1

您正在使用的工具以及您使用该工具的方式将决定您是否需要“;”或不在语句之间。

您的表的其中一个语法是错误的。

create table Vehicle(
    VehicleID number(8) primary key, 
    DriverID number(8) references Driver(DriverID), 
    VehicleAvailable varchar2(5) check(VehicleAvailable IN ('TRUE','FALSE')), -- you forgot the IN keyword
    VehicleRate number(4) not null, 
    VehicleModel varchar2(10) not null, 
    VehicleMake varchar2(10) not null, 
    DateOfRegistration date not null, 
    RegistrationNumber number(8) unique, 
    VehicleColour varchar2(10) not null
);

另外，我建议您将 FK 约束设置为 ALTER TABLE ADD CONSTRAINT 与内联约束。这样您就可以创建所有表、添加约束，而不必担心循环引用或在脚本中正确获取顺序。

像这样，但所有的改动都在你的脚本末尾。

CREATE TABLE admini (
    admin_id     NUMBER(8) PRIMARY KEY,
    employeeid   NUMBER(8),
    bookingid    NUMBER(8) );

ALTER TABLE admini
    ADD CONSTRAINT admini_employeeinformation_fk FOREIGN KEY ( employeeid )
        REFERENCES employeeinformation ( employeeid )
    ENABLE;

ALTER TABLE admini
    ADD CONSTRAINT admini_booking_fk FOREIGN KEY ( bookingid )
        REFERENCES booking ( bookingid )
    ENABLE;
