Hi I am new to Hibernate. I am facing the issues while translating the SQL to HQL. Please find below the SQL query which is executing fine.

select distinct Max(A.TRACK_ID) TRACK_ID, A.EVENT_ID, B.ORG_ARPT_CD, B.DEST_ARPT_CD, C.CRITERIA_DEFINITION, C.EVENT_DEFINITION from EVENT_TRACKER A, FLT_MASTER B, EVENT_DEFINITION C, ( select Max(TRACK_ID) TRACK_ID from EVENT_TRACKER group by FLT_DTL_ID ) D where A.FLT_DTL_ID = B.FLT_DTL_ID And A.EVENT_ID = C.EVENT_ID And C.EVENT_DEFINITION is not null And A.TRACK_ID = D.TRACK_ID And C.EVENT_OWNER = 'U292670' group by A.EVENT_ID, B.ORG_ARPT_CD,B.DEST_ARPT_CD,C.CRITERIA_DEFINITION,C.EVENT_DEFINITION


I write down the below mentioned HQL query like

[SELECT DISTINCT MAX(A.id.trackId), A.eventId, B.origin, B.destination, C.criteriaDefinition, C.eventDefinition FROM com.skytech.rmi.services.domain.EventTracker A, com.skytech.rmi.services.domain.FlightDetails B, com.skytech.rmi.services.domain.EventDefinition C , ( SELECT MAX(eventTr.id.trackId) FROM com.skytech.rmi.services.domain.EventTracker eventTr GROUP BY eventTr.id.fltDtlId )as D WHERE A.id.fltDtlId = B.flightDtlId AND A.eventId = C.eventId AND C.eventDefinition IS NOT NULL AND A.id.trackId = D AND C.eventOwner = 'U292670' GROUP BY A.eventId, B.origin, B.destination, C.criteriaDefinition, C.eventDefinition ORDER BY A.id.trackId DESC, A.eventId, B.origin, B.destination]




In place of D (red color)used: D.id.trackId or D.trackId but still the same kind of exception which is mentioned below.
And I am getting the below mentioned exception like

org.hibernate.hql.ast.QuerySyntaxException: unexpected token: ( near line 1, column 266 [SELECT DISTINCT MAX(A.id.trackId), A.eventId, B.origin, B.destination, C.criteriaDefinition, C.eventDefinition FROM com.skytech.rmi.services.domain.EventTracker A, com.skytech.rmi.services.domain.FlightDetails B, com.skytech.rmi.services.domain.EventDefinition C , ( SELECT MAX(eventTr.id.trackId) FROM com.skytech.rmi.services.domain.EventTracker eventTr GROUP BY eventTr.id.fltDtlId )as D WHERE A.id.fltDtlId = B.flightDtlId AND A.eventId = C.eventId AND C.eventDefinition IS NOT NULL AND A.id.trackId = D AND C.eventOwner = 'U292670' GROUP BY A.eventId, B.origin, B.destination, C.criteriaDefinition, C.eventDefinition ORDER BY A.id.trackId DESC, A.eventId, B.origin, B.destination]

The below mentioned POJO classes have respective member variables


Please help me in this regard.
