[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-3889) Foreign key constraint should not be generated when <any> is used as element in a collection

Foreign key constraint should not be generated when <any> is used as element in a collection -------------------------------------------------------------------------------------------- Key: HHH-3889 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3889 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.3.0.SP1 Environment: hibernate verson = 3.3.0.sp1, db=h2 Reporter: Rice Yeh Let P0, P1 and C are 3 classes. Both P0 and P1 have a set of C. This is like parent-child relationship. In C, there is a field p with type I, which is a interface shared by P0 and P1. These 3 classes are like below: class P0 implements I { Long oid; Set<C> cs; ... } class P1 implements I { Long oid; Set<C> cs; ... } class C { I p; .. } Their hbm mappings are like the following: <class name="P0"> <id name="oid" type="java.lang.Long"> <generator class="native"/> </id> <set name="cs" cascade="all,delete-orphan" inverse="true"> <key column="P_OID" not-null="true"/> <one-to-many class="C"/> </set> </class> <class name="P1"> <id name="oid" type="java.lang.Long"> <generator class="native"/> </id> <set name="cs" cascade="all,delete-orphan" inverse="true"> <key column="P_OID" not-null="true"/> <one-to-many class="C"/> </set> </class> <class name="C"> <id name="oid" type="java.lang.Long"> <generator class="native"/> </id> <any name="p" meta-type="string" id-type="long"> <column name="P_CLASS"/> <column name="P_OID"/> </any> </class> Then 2 foreign key constraints F0 and F1 for P_OID in C to P0 and P1 are created when generated DDL respectively. This is not right because persisting a object p0 in P0 will violate the constraint F1 and persisting a object p1 in P1 will violate the constraint F0.
