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

You can do it in MySQL with the ORDER BY clause. Sort by NULL first, then the date.

SELECT * FROM your_table ORDER BY (date_column IS NULL), date_column ASC

Note: This assumes rows without a date are NULL.

Answer 2

Yes

SELECT * 
  FROM table 
  ORDER BY  CASE your_date 
              WHEN '' THEN 'b' 
              ELSE 'a' 
            END,
            date ASC 

Answer 3

possibly add a NVL( thedate, to_date('2099-12-31','yyyy-mm-dd')) in the order by clause

Answer 4

You can use this:

select * from my_table
order by if(isnull(my_field),1,0),my_field;

Answer 5

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')
