Hibernate SQL for HQL

I'm running into some problems when trying to convert a SQL query to HQL (or Criteria / Restriction). I have the following SQL query:

Select count(n), CreatedDate from (
  Select count(serverId) as n, Date(Created) as CreatedDate 
  from mytable 
  group by Date(Created), serverId
) as tbl 
group by CreatedDate;

      

        
        
        
      

    

So what is the HQL (or Criteria) equivalent?
