hibernate cannot handle Entities with Inheritance and a Discriminator that is part of composite pk -------------------------------------------------------------------------------------------------- Key: HHH-5287 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5287 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.3.2 Environment: Linux, JDK1.6 Reporter: AndyW Attachments: jpatest_hibernate33.zip hi, i am using Hibernate Annotations 3.4.0.GA Hibernate EntityManager 3.4.0.GA Hibernate 3.3.2.GA with JPA 1.0 hibernate fails to create the entities using a SINGLE_TABLE Inheritance when the Discriminator is part of the composite primary key. I have attached a testcase. hibernate is expected to only create a table LADEEINHEIT_EINAUS. however it also creates a table for each of the two entities that extend the base class and defines a DiscriminatorValue @Entity @DiscriminatorValue("EINGANG") public class LadeeinheitEingaenge extends LadeeinheitEinausgaenge @Entity @Inheritance(strategy = InheritanceType.SINGLE_TABLE) @DiscriminatorColumn(name = "LAEA_TYP", discriminatorType = DiscriminatorType.STRING) @Table(name = "LADEEINHEIT_EINAUS") @MappedSuperclass public abstract class LadeeinheitEinausgaenge i have executed the same code using EclipseLink. EclipseLink only created one table 'LADEEINHEIT_EINAUS' which is what i expected. log output from the testcase: 06:59:30,017 [main] DEBUG SchemaUpdate - create table LADEEINHEIT_EINAUS (LAEA_TYP varchar(31) not null, LAEI_AUFT_AUFT_NR bigint not null, LAEI_AUFT_MAND_MAND_NR bigint not null, LAEI_LAEI_LFD_NR bigint not null, LAEA_LOCATION_CODE varchar(6), LAEA_RADIO_CALL_SIGN varchar(4), primary key (LAEA_TYP, LAEI_AUFT_AUFT_NR, LAEI_AUFT_MAND_MAND_NR, LAEI_LAEI_LFD_NR)) 06:59:30,021 [main] DEBUG SchemaUpdate - create table LadeeinheitAusgaenge (LAEA_TYP varchar(10) not null, LAEI_AUFT_AUFT_NR bigint not null, LAEI_AUFT_MAND_MAND_NR bigint not null, LAEI_LAEI_LFD_NR bigint not null, LAEA_LOCATION_CODE varchar(6), LAEA_RADIO_CALL_SIGN varchar(4), primary key (LAEA_TYP, LAEI_AUFT_AUFT_NR, LAEI_AUFT_MAND_MAND_NR, LAEI_LAEI_LFD_NR)) 06:59:30,022 [main] DEBUG SchemaUpdate - create table LadeeinheitEingaenge (LAEA_TYP varchar(10) not null, LAEI_AUFT_AUFT_NR bigint not null, LAEI_AUFT_MAND_MAND_NR bigint not null, LAEI_LAEI_LFD_NR bigint not null, LAEA_LOCATION_CODE varchar(6), LAEA_RADIO_CALL_SIGN varchar(4), primary key (LAEA_TYP, LAEI_AUFT_AUFT_NR, LAEI_AUFT_MAND_MAND_NR, LAEI_LAEI_LFD_NR)) cheers, andy -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
