数据库alter table报错1064

Question

数据库问题最后两行代码报错1065

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 fk1_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)

查询：ALTER TABLE Student ADD CONSTRAINT fkl_student FOREIGN KEY (campus_id) REFERENCES campus (campus_id) ALTER TABLE `Stud。

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 'ALTER TABLE Student ADD CONSTRAINT fk2_student FOREIGN KEY (`trainning_site_' at line 2
