sql - SQL 表创建代码给出错误

Question

有人可以帮我看看这个吗，我似乎无法找到它为什么不起作用。

CREATE TABLE Person(
Person_ID int auto_increment NOT NULL,
Person_Type_ID int NOT NULL,
Create_Date datetime NOT NULL ,
Modify_Date datetime NOT NULL ,
First_Name varchar(50) NOT NULL,
Surname varchar(50) NOT NULL,
DOB date NOT NULL,
Gender char(1) NOT NULL CHECK (Gender ='f' OR Gender ='m'),
Archive char(1) NULL,
Allergies varchar(200) NOT NULL,
Dietry_Requirements varchar(200) NOT NULL,
Disabilities varchar(200) NOT NULL,
Medicine_Requirements varchar(200) NOT NULL,
    username varchar (30) NOT NULL,
password varchar (30) NOT NULL,
CONSTRAINT PK_Person_ID PRIMARY KEY (Person_ID)
CONSTRAINT FK_Person_Type_ID FOREIGN KEY (Person_Type_ID)
REFERENCES Person_Type (Person_Type_ID));

你漏了一个逗号！这应该工作...

CREATE TABLE Person(
Person_ID int auto_increment NOT NULL,
Person_Type_ID int NOT NULL,
Create_Date datetime NOT NULL ,
Modify_Date datetime NOT NULL ,
First_Name varchar(50) NOT NULL,
Surname varchar(50) NOT NULL,
DOB date NOT NULL,
Gender char(1) NOT NULL CHECK (Gender ='f' OR Gender ='m'),
Archive char(1) NULL,
Allergies varchar(200) NOT NULL,
Dietry_Requirements varchar(200) NOT NULL,
Disabilities varchar(200) NOT NULL,
Medicine_Requirements varchar(200) NOT NULL,
username varchar (30) NOT NULL,
password varchar (30) NOT NULL,
CONSTRAINT PK_Person_ID PRIMARY KEY (Person_ID),
CONSTRAINT FK_Person_Type_ID FOREIGN KEY (Person_Type_ID)
REFERENCES Person_Type (Person_Type_ID));
