PHP, MYSQL: Order by date but empty dates last not first

Question

I fetch an array with todo titles and due dates from MySQL. I want to order it by date and have the oldest on top. But there are some todos without a date. These todos I don\'t

Answer 1

Well, as a pure MySQL answer, I would probably do it like this.

  select todo.title, todo.due_date
    from todo
    order by ifnull(todo.due_date, '9999-12-31')
