CREATE TABLE department ( department_id INT PRIMARY KEY, department_name VARCHAR(50) NOT NULL, manager_id INT, location_id INT, FOREIGN KEY (manager_id) REFERENCES employee(employee_id), FOREIGN KEY (location_id) REFERENCES location(location_id) );

注解:

  • department_id:部门ID,是主键;
  • department_name:部门名称,不能为空;
  • manager_id:部门经理的员工ID,可以为空;
  • location_id:部门所在地的ID,可以为空;
  • manager_id和location_id都是外键,分别引用了员工表和地点表的主键。
