如何插入多对多记录数据？

CREATE TABLE student_course (
  student_id INT,
  course_id INT,
  PRIMARY KEY (student_id, course_id),
  FOREIGN KEY (student_id) REFERENCES students(id),
  FOREIGN KEY (course_id) REFERENCES courses(id)
);

INSERT INTO students (id, name) VALUES (1, 'Alice');
INSERT INTO students (id, name) VALUES (2, 'Bob');

INSERT INTO courses (id, name) VALUES (1, 'Math');
INSERT INTO courses (id, name) VALUES (2, 'Science');

INSERT INTO student_course (student_id, course_id) VALUES (1, 1); -- Alice选修Math课程
INSERT INTO student_course (student_id, course_id) VALUES (1, 2); -- Alice选修Science课程
INSERT INTO student_course (student_id, course_id) VALUES (2, 2); -- Bob选修Science课程
