Translating to detachedCriteria

How can I translate the following query to detachedCriteria:

select * from (
    select a.* ,row_num开发者_运维问答ber() over (partition by hotel_id order by  EXECUTION_START_DATE desc)  rnk  
    from HOLIDAY_PACKAGES a
)
where rnk = 1

I don't think you will be able to construct such a query using the Criteria API. The only way to go is through the Native SQL support or in the worst case scenario use a stored procedure.
