title: The default sorting criteria of sqlalchemy?
body: <p>Now I sort the data in the database by its attribute 1. 
  If there is a tie of different items with same value of attribute 1, the data seems to be sorted by its id. 
  However, I would like to break the tie by sorting by desc(id). How could I change the default sorting criteria of the database if there is a tie?</p>
  
  <p>Thanks!</p>
