I want to create a view from two tables using annotions in java/JEE ,
so after some researches i found that the only way to do it is using @Subselect
annotation so I created 3 entities
the test entity



 @Table
@Entity
public class Test {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private long id;
@Column
private String nom;
@Column
private String prenom;
@Column
private int age;
@Column
private String adresse;
@Column
private Date dateNaissance;
// getters and setters
}


The compte entity



 @Entity
public class Compte {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private long id;
@Column
private long solde;
@Column
private long numero;
@Column
private String description;
// getters and setters
}


and the entity Compte_Test wich has the same role as a view



@Entity
@Subselect("SELECT c2.id as idTest,c1.id as id,c1.solde as solde,c1.numero as numero, c2.nom as nom, c2.prenom as prenom FROM Compte c1 INNER JOIN Test c2 ON c1.id_test= c2.id")
@Synchronize({ "compte", "test" })
public class Compte_Test {

@Id
private long idCompte_Test;
@Column
private long idTest;
@Column
private long id;
@Column
private long solde;
@Column
private long numero;
@Column
private String nom;
@Column
private String prenom;

// getters and setters
}


I'am using spring data @Query annotaion to get data from Compte_Test entity



@Query(value = "SELECT c from Compte_Test c ")
List<Compte_Test> fullTextSearch(Pageable pageable);


The problem is that it generates for me an error



org.postgresql.util.PSQLException: ERROR: column compte_tes0_.id_compte_test does not exist
Position : 8
at org.postgresql.core.v3.QueryExecutorImpl.receiveErrorResponse(QueryExecutorImpl.java:2440) ~[postgresql-42.2.5.jar:42.2.5]

    have you checked the database for the column? Is it exactly as query expects? The name idCompte_Test is a bit unusual name and Hibernate by default seems to prefix capital-camel-case with _ also so this miight be the problem.

  • the table isn't even created in the db

  • Well, that is a bigger problem then. About the subselect, do you think you could achieve the same result by other means, like my answer to this quiestion suggests?
