| I've the following Entity
@Entity
@Table(name="cod__postales")
public class CodigoPostal {
@Id
@GeneratedValue
private Long registro;
@Column(name = "`POST_Nº_CODIGO`", length = 6, nullable = false)
private String codigo = " ";
@Column(name = "POST_DESCRIP", length = 30, nullable = false)
private String descripcion = " ";
@Column(name = "POST_ZONA_ASIG", length = 2, nullable = false)
private String zona = " ";
...
}
Also I've the following Spring JPA Repository:
public interface CodigoPostalRepository extends JpaRepository<CodigoPostal, Long> {
CodigoPostal findOneByCodigo(String codigo);
}
As you can see, there is a special character on the first column name 'º'. The problem is that, when I call to repo.findOneByCodigo() method, the following SQL is generated:
select codigopost0_.registro as registro1_2_,
codigopost0_.`post_nº_codigo` as post_nº_2_2_,
codigopost0_.post_descrip as post_des3_2_,
codigopost0_.post_zona_asig as post_zon4_2_
from cod__postales codigopost0_
where codigopost0_.`post_nº_codigo`=?
The problem is that sql gives an error because of the name Hibernate assings to that column: as post_nº_2_2_. The generated SQL should be put inside `` the same way I've put the column name inside the @Column annotation Aditional Data: 2016-02-02 11:53:07.372 DEBUG 8185 — [ main] o.h.h.internal.ast.QueryTranslatorImpl : — HQL AST —
