Refer to the code below for generating the teacher sample table:

CREATE TABLE teacher (
id INT AUTO_INCREMENT,
teacher_name VARCHAR(30),
pupil_id INT UNSIGNED, -- This is our foreign key.
department VARCHAR(30),
PRIMARY KEY (id),
FOREIGN KEY (pupil_id) REFERENCES pupil(id) -- Important!
);

INSERT INTO teacher(name, pupil_id, department)
VALUES ('emily', 1, 'physics'), ('fiona', 2, 'physics'), ('gilbert', 3, 'chemistry');

SELECT * FROM teacher;
+----+---------------+----------+------------+
| id | teacher_name | pupil_id | department |
+----+---------------+----------+------------+
| 1 | emily | 1 | physics |
| 2 | fiona | 2 | physics |
| 3 | gilbert | 3 | chemistry |
+----+---------------+----------+------------+
