MySQL: ORDER BY with empty date '0000-00-00' as last but the rest ASC

Question

In our database, instead of making empty dates NULL, they are '0000-00-00' (I know, it sucks). How can I order these so that dates that are not '0000-00-00' are first and ordered ASC, and then the empty dates of '0000-00-00' come after?

Thanks!

Try Below :

  SELECT * FROM your_table ORDER BY (date_column='0000-00-00'), date_column ASC
