i want to convert this query to HQL
select status,count(*) from server s, status st where s.id = st.server_id and st.created = (select max(ss.created) from status ss where ss.server_id = s.id) group by st.status
i tried this
@Query("select new StatisticServerDTO( st.status, count(*)) from Server s, Status st where "
+ "s.id = st.server.id and st.created = (select max(ss.created) from Status ss where ss.server.id = s.id)"
+ "group by st.status")
List<StatisticServerDTO> nbrServerByStatus();
but its not working
my return class is like :
public class StatisticServerDTO{
private String status;
private int nbr;
...
}
the exception is:
Caused by: java.lang.IllegalStateException: No data type for node: org.hibernate.hql.internal.ast.tree.MethodNode
\-[METHOD_CALL] MethodNode: '('
+-[METHOD_NAME] IdentNode: 'StatisticServerDTO' {originalText=StatisticServerDTO}

You are missing New in your query
@Query("select NEW StatisticServerDTO( st.status, count(*)) from Server s, Status st where " + "s.id = st.server.id and st.created = (select max(ss.created) from Status ss where ss.server.id = s.id)" + "group by st.status") List nbrServerByStatus();
