You can specifying multiple columns in the ORDER BY clause as shown in the following example statement, which returns employees' salaries sorted by department and salary value:

SQL> SELECT department_id, first_name, last_name, salary 
  FROM employees ORDER BY department_id, salary;
DEPARTMENT_ID FIRST_NAME      LAST_NAME           SALARY
------------- --------------- --------------- ----------
           10 Jennifer        Whalen                4400
           20 Pat             Fay                   6000
           20 Michael         Hartstein            13000
