EntityManager doesn't care about INSERT trigger of Oracle XE ------------------------------------------------------------ Key: EJB-381 URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-381 Project: Hibernate Entity Manager Issue Type: Bug Affects Versions: 3.4.0.GA Environment: Hibernate EM 3.4.0, Hibernate Annotations 3.4.0, Hibernate Commons Annotations 3.1.0, Hibernate 3.3.0.SP1, Hibernate Validator 3.1.0.CR2, JDK 1.6.0_07 Reporter: Juergen Zimmermann I have an abstract entity class with 2 derived concrete classes: @Entity @Table(name="kunde") @Inheritance @DiscriminatorColumn(name="art", length=1) @XmlRootElement @XmlSeeAlso({ Firmenkunde.class, Privatkunde.class }) @XmlAccessorType(XmlAccessType.FIELD) public abstract class Kunde implements java.io.Serializable { @Id @GeneratedValue(generator="kunde_sequence_name") @SequenceGenerator(name="kunde_sequence_name", sequenceName="kunde_k_id_seq", allocationSize=1) @Column(name="k_id", nullable=false) @XmlAttribute(name="id", required=true) protected Long id = KEINE_ID; @Version @XmlTransient protected int version = ERSTE_VERSION; @Column(length=32, nullable=false) @XmlElement(required=true) protected String nachname = ""; ... @Column(length=32, unique=true) protected String username = ""; ... } The table is created as follows: CREATE TABLE kunde( k_id NUMBER(16) NOT NULL PRIMARY KEY, version NUMBER(8) DEFAULT 0, nachname VARCHAR2(32) NOT NULL, ... art VARCHAR2(2) DEFAULT 'P', ... username VARCHAR2(32) NOT NULL UNIQUE, ... ); Additionally there is this sequence and insert trigger for column username. CREATE SEQUENCE kunde_k_id_seq START WITH 200 NOMAXVALUE / CREATE OR REPLACE TRIGGER kunde_trigger_insert BEFORE INSERT ON kunde FOR EACH ROW BEGIN :NEW.username := TO_CHAR(:NEW.k_id); END; / New objects are inserted into the database using this code which works fine with PostgreSQL. However, using Oracle XE the insert trigger isn't considered: public List<Kunde> insertKunden(List<Kunde> kunden) { if (kunden == null || kunden.isEmpty()) { return new ArrayList<Kunde>(0); } for (Kunde k: kunden) { em.persist(k); } return kunden; } The attribute "username" is null using Oracle XE, but using PostgreSQL it has the value produced by the INSERT trigger. -- 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
