Get record with max id, using Hibernate Criteria

Question

Using Hibernate\'s Criteria API, I want to select the record within a table with the maximum value for a given column.

I tried to use Projections, creating an alias

Answer 1

HQL:

from Person where person.id = (select max(id) from Person)

Untested. Your database needs to understand subselects in the where clause.

Too lazy to find out if/how such a subselect can be expressed with the criteria api. Of course, you could do two queries: First fetch the max id, then the entity with that id.
