SELECT `field1`, `field2`, STR_TO_DATE(`datefield`,'%d-%m-%Y :: %h:%i:%s') AS mydate FROM `table1` ORDER BY mydate;

Don't know if that will work. Can you order on the calculated field?? Sorry brain frazzled.

I think you need to do:

SELECT STR_TO_DATE(`datefield`, '%d-%m-%Y :: %h:%i:%s') AS mydate
FROM `table1` 
ORDER BY STR_TO_DATE(`datefield`, '%d-%m-%Y :: %h:%i:%s') DESC LIMIT 1
