I am trying to fetch a PlaceEntity
. I've previously stored a bunch of GooglePlaceEntity
objects where
@Entity
@Table(name = "place")
@Inheritance(
strategy = InheritanceType.JOINED
)
public class PlaceEntity extends AbstractTimestampEntity {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
}
and
@Entity
@Table(name = "google_place")
public class GooglePlaceEntity extends PlaceEntity {
// Additional fields ..
}
However, neither do I want to send information stored in google_place
nor do I want to load it unnecessarily. For this reason I am only fetching
public interface PlaceRepository extends JpaRepository<PlaceEntity, Long> {
@Query(value = "" +
"SELECT * " +
"FROM place " +
"WHERE earth_distance( " +
" ll_to_earth(place.latitude, place.longitude), " +
" ll_to_earth(:latitude, :longitude) " +
") < :radius",
nativeQuery = true)
List<PlaceEntity> findNearby(@Param("latitude") Float latitude,
@Param("longitude") Float longitude,
@Param("radius") Integer radius);
}
and what I get is this:
org.postgresql.util.PSQLException: The column name clazz_ was not found in this ResultSet.
at org.postgresql.jdbc.PgResultSet.findColumn(PgResultSet.java:2588) ~[postgresql-9.4.1208-jdbc42-atlassian-hosted.jar:9.4.1208]

at org.hibernate.type.descriptor.sql.BasicExtractor.extract(BasicExtractor.java:47) ~[hibernate-core-5.2.14.Final.jar:5.2.14.Final]
...
I am able to run this statement in pure PostgreSQL:
SELECT * FROM place WHERE
earth_distance(
ll_to_earth(place.latitude, place.longitude),
ll_to_earth(17.2592522, 25.0632745)
) < 1500;
but not using the JpaRepository
.
And by the way, fetching a GooglePlaceEntity
is working however:
@Query(value = "" +
"SELECT * " +
"FROM place JOIN google_place ON google_place.id = place.id " +
"WHERE earth_distance( " +
" ll_to_earth(place.latitude, place.longitude), " +
" ll_to_earth(:latitude, :longitude) " +
") < :radius",
nativeQuery = true)
List<GooglePlaceEntity> findNearby(@Param("latitude") Float latitude,
@Param("longitude") Float longitude,
@Param("radius") Integer radius);
