Nullable ID columns are generated which causes test test failures for DB2 (because it does not allow primary key columns to be nullable).
Example 1:
{{@Entity
@IdClass(DependentId.class)
public class Dependent {
@Id
String name;
@Id @ManyToOne
@JoinColumns( { @JoinColumn(name="FK1", referencedColumnName="firstName"), @JoinColumn(name="FK2", referencedColumnName="lastName") }
)
Employee emp;
}
}}
Reproduced by (both are regresssions):
org.hibernate.test.annotations.derivedidentities.e2.a.DerivedIdentityIdClassParentIdClassDepTest (Employee has @IdClass.
org.hibernate.test.annotations.derivedidentities.e3.a.DerivedIdentityEmbeddedIdParentIdClassTest (Employee has @EmbeddedId.
Example 2:
{{@Entity
public class Dependent {
@EmbeddedId
DependentId id;
@MapsId("empPK")
@JoinColumns( { @JoinColumn(name = "FK1", referencedColumnName = "FIRSTNAME"), @JoinColumn(name = "FK2", referencedColumnName = "lastName") }
)
@ManyToOne
Employee emp;
}
}}
Reproduced by:
-
org.hibernate.test.annotations.derivedidentities.e3.b.DerivedIdentityEmbeddedIdParentEmbeddedIdDepTest (Employee has @EmbeddedId) (regression).
Example 3:
@Entity
public class MedicalHistory {
@EmbeddedId
PersonId id;
@MapsId
@JoinColumns( { @JoinColumn(name = "FK1", referencedColumnName = "firstName"), @JoinColumn(name = "FK2", referencedColumnName = "lastName") }
)
@OneToOne
Person patient;
}
Reproduced by:
-
DerivedIdentityIdClassParentSameIdTypeEmbeddedIdDepTest (regression)
-
DerivedIdentityEmbeddedIdParentSameIdTypeEmbeddedIdDepTest (regression)
Following test also incorrectly generate ID columns that are nullable (introduced by
HHH-5764
):
