sql - SQL Query returning dates in descending order

Question

I'm using my phpmyadmin which is linked up to our CRM system where we can pull reports from our DB. I'm trying to return a report where the dates will be in descending order - however my query doesn't seem to be returning the order by command correctly.

Query I have is:

SELECT emp.emp_firstname as `first name` 
     , emp.emp_lastname as `last name`
     , emp.emp_work_email as `email` 
     , emp.custom6 as `Agency` 
     , emp.employee_id as `crewcode` 
     , emp.custom67 as `nationality`
     , emp.custom14 as `Salary options`
     , emp.custom15 as `Salary options comments`
     , emp.custom17 as `Salary options date of change`
     , emp.custom30 as `Bank Cert` 
FROM `hs_hr_employee` emp  
WHERE emp.custom61 LIKE "active-oam" 
ORDER by emp.custom17 DESC

Answer 1

 SELECT emp.emp_firstname as `first name` 
 , emp.emp_lastname as `last name`
 , emp.emp_work_email as `email` 
 , emp.custom6 as `Agency` 
 , emp.employee_id as `crewcode` 
 , emp.custom67 as `nationality`
 , emp.custom14 as `Salary options`
 , emp.custom15 as `Salary options comments`
 , emp.custom17 as `Salary options date of change`
 , emp.custom30 as `Bank Cert` 
  FROM `hs_hr_employee` emp  
  WHERE emp.custom61 LIKE "active-oam" 
  ORDER by emp.custom17 DESC, emp.employee_id DESC
