  - by Buzz

  I have a column of states, and, depending on the query, I want to order by results by a particular state, then by id (Asc or Desc, depending). For instance, I might want to show all rows with state "HI", sorted by ID desc, and then all the other rows, sorted by id desc. I was hoping I could do this in one query, rather than getting all my favored state results, and then getting the rest. Can I?
