数据库语法问题
CREATE TABLE student (Student_id INT NOT NULL PRIMARY KEY,campus_id INT NOT NULL,trainning_site_id INT NOT NULL,full_name VARCHAR(20) NOT NULL ,age INT NOT NULL,email VARCHAR(50) NOT NULL
)
CREATE TABLE car(rego_number VARCHAR(20) NOT NULL PRIMARY KEY,owner_id INT NOT NULL,owner_name VARCHAR(20) NOT NULL ,
CONSTRAINT fkl_car FOREIGN KEY (owner_id) REFERENCES Student (Student_id)
)
CREATE TABLE campus (campus_id INT NOT NULL PRIMARY KEY,campus_location VARCHAR(30) NOT NULL
)
CREATE TABLE trainning_site(trainning_site_id INT NOT NULL PRIMARY KEY,
trainning_site_location VARCHAR(30) NOT NULL
)
ALTER TABLE Student ADD CONSTRAINT fkl_student FOREIGN KEY (campus_id) REFERENCES campus (campus_id)
ALTER TABLE Student ADD CONSTRAINT fk2_student FOREIGN KEY (trainning_site_id) REFERENCES trainning_site(trainning_site_id)
错误代码： 1064
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'CREATE TABLE car(rego_number varchar(20) not null primary key,owner_id' at line 9
如何解决这一项问题，语法哪里有问题
在每一个create语句最后加个分号";"试试
执行完一条建表语句后加上分号
CREATE TABLE student (
Student_id INT NOT NULL PRIMARY KEY,
campus_id INT NOT NULL,
trainning_site_id INT NOT NULL,
full_name VARCHAR(20) NOT NULL ,
age INT NOT NULL,
email VARCHAR(50) NOT NULL
);
CREATE TABLE car(
rego_number VARCHAR(20) NOT NULL PRIMARY KEY,
owner_id INT NOT NULL,
owner_name VARCHAR(20) NOT NULL ,
CONSTRAINTfkl_car FOREIGN KEY (owner_id) REFERENCES Student (Student_id)
)
CREATE TABLE student (
Student_id INT NOT NULL PRIMARY KEY,
campus_id INT NOT NULL,
trainning_site_id INT NOT NULL,
full_name VARCHAR(20) NOT NULL ,
age INT NOT NULL,
email VARCHAR(50) NOT NULL
);
CREATE TABLE car(
rego_number VARCHAR(20) NOT NULL PRIMARY KEY,
owner_id INT NOT NULL,
owner_name VARCHAR(20) NOT NULL ,
CONSTRAINTfkl_car FOREIGN KEY (owner_id) REFERENCES Student (Student_id)
);
CREATE TABLE campus (
campus_id INT NOT NULL PRIMARY KEY,
campus_location VARCHAR(30) NOT NULL
);
CREATE TABLE trainning_site(
trainning_site_id INT NOT NULL PRIMARY KEY,
trainning_site_location VARCHAR(30) NOT NULL
);
ALTER TABLE Student ADD CONSTRAINT fkl_student FOREIGN KEY (campus_id) REFERENCES campus (campus_id);
ALTER TABLE Student ADD CONSTRAINT fk2_student FOREIGN KEY (trainning_site_id) REFERENCES trainning_site(trainning_site_id);
试一下！
