Question

I have a query where i am joining two tables ROuteMaster and RouteHalts.
When i perform inner join i am getting

org.hibernate.hql.ast.QuerySyntaxException: unexpected token: on near line 1, 

column 169 [SELECT  rm.id , rm.routeCode , rm.startPlaceId , rm.endPlaceId , 
rm.active, rm.linkedRoute FROM com.oprs.pojo.routes.RouteMaster rm  INNER JOIN 
RouteHalts rh  on rm.id = rh.routeId  WHERE  rh.placeId = :PlaceId  
ORDER BY  rm.id  ASC]

I searched through the site and found similar question and the response for it. the question referred was

Hibernate: org.hibernate.hql.ast.QuerySyntaxException: unexpected token

I have many-to-one mapping in RouteHalts for RouteMaster, I have defined getter and setter methods for RouteMaster in RouteHalts

<many-to-one name="RouteMaster" class="com.oprs.pojo.routes.RouteMaster" 
                    fetch="join"
            foreign-key="id" column="ROUTE_ID" insert="false"
            update="false" lazy="false" />

but still getting the same error. Can please some one guide me.

Answer 1

You should not use explicit “JOIN ON” in HQL. Instead you can use implicit joining in HQL:

SELECT  rm.id , rm.routeCode , rm.startPlaceId , rm.endPlaceId , rm.active , rm.linkedRoute 
FROM com.abhibus.oprs.pojo.routes.RouteMaster rm  
INNER JOIN rm.routeHalts rh WHERE  rh.placeId = :PlaceId  ORDER BY  rm.id  ASC

or you can use Theta style for writing join:

SELECT  rm.id , rm.routeCode , rm.startPlaceId , rm.endPlaceId , rm.active , rm.linkedRoute 
FROM com.abhibus.oprs.pojo.routes.RouteMaster rm, RouteHalts rh
WHERE rm.id = rh.routeId AND rh.placeId = :PlaceId  ORDER BY  rm.id  ASC

Also you can execute your query as native SQL query, not HQL query. For this you should use

session.createSQLQuery(queryText);

instead of

session.createQuery(queryText);

And by the way, may be in your case in is better to fetch whole entity, not separated fields (columns)? For this you can use:

select rm from ...

This will return the List<RouteMaster> insted of List<Object[]>.
