Question

I have the following Java 6 code:

    Query q = em.createNativeQuery(          'select T.* ' +         'from Trip T join Itinerary I on (T.itinerary_id=I.id) ' +         'where I.launchDate between :start and :end ' +         'or ADDDATE(I.launchDate, I.equipmentPullDayOfTrip) between :start and :end',         'TripResults' );      q.setParameter( 'start', range.getStart(), TemporalType.DATE );     q.setParameter( 'end', range.getEnd(), TemporalType.DATE );      @SqlResultSetMapping( name='TripResults',         entities={             @EntityResult( entityClass=TripEntity.class ),             @EntityResult( entityClass=CommercialTripEntity.class )         }     ) 

I receive a syntax error on the last closing right parenthesis. Eclipse gives: ‘Insert EnumBody to complete block statement’ and ‘Insert enum Identifier to complete EnumHeaderName’. Similar syntax error from javac.

What am I doing wrong?

The Hibernate annotations docs (http://www.hibernate.org/hib_docs/annotations/reference/en/html_single/) suggest that this should be a class-level annotation rather than occurring inline within your code. And indeed when I paste that code into my IDE and move it around, the compile errors are present when the annotation is inline, but vanish when I put it in above the class declaration:

@SqlResultSetMapping( name='TripResults',         entities={             @EntityResult( entityClass=TripEntity.class ),             @EntityResult( entityClass=CommercialTripEntity.class )         }     ) public class Foo {    public void bogus() {       Query q = em.createNativeQuery(          'select T.* ' +         'from Trip T join Itinerary I on (T.itinerary_id=I.id) ' +         'where I.launchDate between :start and :end ' +         'or ADDDATE(I.launchDate, I.equipmentPullDayOfTrip) between :start and :end',         'TripResults' );        q.setParameter( 'start', range.getStart(), TemporalType.DATE );       q.setParameter( 'end', range.getEnd(), TemporalType.DATE );    } } 

…obviously I have no evidence that the above code will actually work. I have only verified that it doesn’t cause compile errors.
