Be aware though, if you're using ActiveRecord 1.0.3 (RC3) as I was, this will result in a runtime InvalidCastException. ActiveRecordMediator.ExecuteQuery returns an ArrayList and not a generic ICollection. So in order to make it work, just change this line:

var results = (ICollection) ActiveRecordMediator.ExecuteQuery(query);

to

var results = (ArrayList) ActiveRecordMediator.ExecuteQuery(query);

and it should work.

Also note that using count(1) in your hql statement will make the query return an ArrayList of String instead of an ArrayList of object[] (which is what you get when using count(*).)

Just thought I'd point this out for the sake of having it all documented in one place.
