The #SqlResultSetMapping usage cause the schema validation problem - spring

Question

I have to extract data for statistic purpose. I've created a native query and used #SqlResultSetMapping to map the resultset to an object.
Hibernate needs to declare this class (Elaboration) as #Entity BUT IS NOT A TABLE, and I don't want a table because I have only to extract data on the fly when needed.
The code works fine but the gitlab pipeline fails during validation with
schemaManagementException: Schema-validation: missing table [elaboration].
Here my code so far:
SqlResultSetMapping(name="ValueMapping",
classes={
#ConstructorResult(
targetClass=Elaboration.class,
columns={
#ColumnResult(name="areadesc", type=String.class),
#ColumnResult(name="subsectordesc", type=String.class),
#ColumnResult(name="eurovalue", type=BigDecimal.class),
#ColumnResult(name="eurotch", type=BigDecimal.class),
}
)
})
#Entity
public class Elaboration{
#Id
private Long id;
private String areadesc;
private String subsectordesc;
private Integer dossiercount;
private BigDecimal eurovalue;
private BigDecimal eurotch;
....
and the custom query:
String statisticValueQuery = "select a.mdescr as areadesc, s.mdescr as subsectordesc, sum(euro_value) as eurovalue,
sum(euro_value_tch) as eurotch " +
"from dossier d " +
"join dossier_document dd on d.id = dd.dossier_id " +
"join dossier_country dc on d.id = dc.dossier_id " +
"join country c on dc.country_id = c.id " +
"join area a on c.area_id = a.id " +
"join dossier_subsector ds on d.id = ds.dossier_id " +
"join subsector s on ds.subsector_id = s.id " +
"where dd.document_id = :document " +
"and d.submission_date >= :startdate and d.submission_date <= :enddate " +
"group by s.id, a.id;";
public List<Elaboration> getValueElaboration(ElaborationRequestDTO elaborationRequestDTO){
Query resultMapping = em.createNativeQuery(statisticValueQuery, "ValueMapping");
resultMapping.setParameter("startdate", elaborationRequestDTO.getElaborateFromEquals());
resultMapping.setParameter("enddate", elaborationRequestDTO.getElaborateToEquals());
resultMapping.setParameter("document", elaborationRequestDTO.getDocumentIdEquals());
return resultMapping.getResultList();
Is there a way to pass the validation test?
Thanks

This is wrong statement.
Hibernate needs to declare this class (Elaboration) as #Entity
You should just put your #SqlResultSetMapping declaration above some #Entity but it can be some other entity not related to the Elaboration.
#SqlResultSetMapping(name="ValueMapping",
classes={
#ConstructorResult(
targetClass=Elaboration.class,
columns={
#ColumnResult(name="areadesc", type=String.class),
#ColumnResult(name="subsectordesc", type=String.class),
#ColumnResult(name="eurovalue", type=BigDecimal.class),
#ColumnResult(name="eurotch", type=BigDecimal.class),
}
)
})
#Entity
public class SomeEntity {
}
And if Elaboration is not an entity you should not annotate it as such.
