alternative code

Is this a valid solution?

CREATE OR REPLACE VIEW v_dm_salary AS
    SELECT 
        ROUND(AVG(salary), 2) AS ave_salary
    FROM
        salaries s
    WHERE
        EXISTS( SELECT 
                dm.emp_no
            FROM
                dept_manager dm
            WHERE
                s.emp_no = dm.emp_no);
            
SELECT 
    *
FROM
    v_dm_salary;
