You can create a new view based on one or more existing tables by using the CREATE VIEW statement as shown in the following script:

CREATE VIEW employee_department AS 
  SELECT e.employee_id, e.first_name, e.last_name, 
    e.email, e.manager_id, d.department_name 
  FROM employees e, departments d
  WHERE e.department_id = d.department_id;
View created.

SELECT first_name, last_name, department_name 
  FROM employee_department WHERE manager_id = 101;
FIRST_NAME           LAST_NAME           DEPARTMENT_NAME
