Question

您好我是SQL新手并且在创建表时遇到问题。我过去两天一直在看这个代码，我似乎无法让它工作。它一直给我“ORA-00907：错过右括号”我知道这是一个很多但是由于某种原因出现的主题，但我看到的所有例子都没有帮助过我。有人可以告诉我为什么我得到这个错误，我该如何解决它。我很确定它与我的括号无关，也许是我的反对意见这是我的代码

create TABLE Employee
(
EmployeeID VARCHAR(10) PRIMARY KEY,
Name VARCHAR(30) NOT NULL,
Phone INT(10) NOT NULL,
JobTitle VARCHAR(10) NOT NULL
);


create TABLE Airplane
(
AirplaneID VARCHAR(10) PRIMARY KEY,
Capacity INT(1000) NOT NULL,
Modle VARCHAR(10) NOT NULL
);


create TABLE Route
(
FlightID VARCHAR(10) PRIMARY KEY,
Origin VARCHAR(20) NOT NULL,
Destination VARCHAR(20) NOT NULL,
ETD INT(10) NOT NULL,
ETA INT(10) NOT NULL
);


create TABLE Customer
(
CustomerID VARCHAR(10) PRIMARY KEY,
Name VARCHAR(10) NOT NULL,
PhoneNumber INT(30) NOT NULL
);


create TABLE Maintenance
(
MaintenanceID VARCHAR(20) PRIMARY KEY,
MaintenanceDate date NOT NULL,
AirplaneID VARCHAR(10) NOT NULL,
EmployeeID VARCHAR(10) NOT NULL,
FOREIGN KEY (AirplaneID) REFERENCES Airplane(AirplaneID),
FOREIGN KEY (EmployeeID) REFERENCES Employee(EmployeeID)
);

create TABLE Flight
(
FlightID VARCHAR(10),
FlightDate date,
AirplaneID VARCHAR(10),
ATD INT(10) NOT NULL,
ATA INT(10) NOT NULL,
FOREIGN KEY (FlightID) REFERENCES Flight(FlightID),
FOREIGN KEY (AirplaneID) REFERENCES Airplane(AirplaneID),
CONSTRAINT PK_FlightID PRIMARY KEY (FlightID,FlightDate)
);



create TABLE Reservation
(
ReservationID VARCHAR(20) PRIMARY KEY,
CustomerID VARCHAR(10) NOT NULL,
FlightID VARCHAR(10) NOT NULL,
FlightDate date NOT NULL,
Fare float,
PaymentMethod VARCHAR(20),
CardNumber INT(30) NOT NULL,
ExperationDate date,
check (PaymentMethod = "Cash" OR PaymentMethod ="Credit" OR PaymentMethod 
="Cheque",
FOREIGN KEY (CustomerID) REFERENCES Customer(CustomerID),
FORIGN KEY (FlightID,FlightDate) REFERENCES Flight(FlightID,FlightDate)
);

create TABLE CrewResveration
(
EmployeeID VARCHAR(10),
FlightID VARCHAR(10),
FlightDate date NOT NULL,
Role VARCHAR(20) NOT NULL,
ShiftHour INT(10) NOT NULL,
FORIGN KEY (FlightID,FlightDate) REFERENCES Flight(FlightID,FlightDate)
FORIGNKEY (EmployeeID) REFERENCES Employee(EmployeeID) 
CONSTRAINT PK_CrewAssignment PRIMARY (FlightID,FlightDate,EmployeeID)
);

以下是我运行代码时得到的结果：

Answer 1

问题在于您的数据类型。 INT不是有效的Oracle数据类型。试试这个：

create TABLE Employee ( EmployeeID VARCHAR(10) PRIMARY KEY, 
                        Name VARCHAR(30) NOT NULL, 
                        Phone NUMBER(10) NOT NULL, 
                        JobTitle VARCHAR(10) NOT NULL );

Answer 2

错误描述具有误导性，但指针（第5行，第10列）在读取“INT”之后完全指向......这是他所不知道的。他应该说他不理解这一点，但他提到了一些带括号的东西，具有讽刺意味的是，它实际上是正确的。不幸的是，它偶尔会出现错误消息的误导，你必须更进一步思考。
