APAR status
Closed as program error.
Error description
When removing @Embeddable objects from an @ElementCollection that contain fields of type CLOB, EclipseLink will construct queries that contain CLOB field types in WHERE clauses. This is not valid for Oracle databases and will result in an ORA-00932 exception. This APAR adds support to the EclipseLink persistence provider for CLOB field types in ElementCollections.

Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server Liberty - Java Persistence APA - JPA * * 2.1 & EclipseLink & Oracle * **************************************************************** * PROBLEM DESCRIPTION: EclipseLink creates a DELETE statement * * containing CLOB fields, which throws * * exception ORA-00932 on Oracle DB * **************************************************************** * RECOMMENDATION: * **************************************************************** Example JPA Entity mapping: @Embeddable public class CollectedEntity { @Lob @Column(name = "content", nullable = false) private String content; } @Entity public class ParentEntity { @ElementCollection(fetch = FetchType.EAGER) @CollectionTable( joinColumns = { @JoinColumn(name = "parent_id", referencedColumnName = "id"), @JoinColumn(name = "parent_version", referencedColumnName = "version") }) private Set<CollectedEntity> subs; } Observe in this example that the @ElementCollection, Set<CollectedEntity>, has a @Lob field. If the application code performs a removal from this Set and attempts to merge the entity back to the persistence context, EclipseLink will construct a DELETE query to remove from ParentEntity. For instance: em = emf.createEntityManager(); final Set<CollectedEntity> col1 = new HashSet<CollectedEntity>( Arrays.asList(new CollectedEntity[] { new CollectedEntity("label1", "content1"), new CollectedEntity("label2", "content2"), new CollectedEntity("label3", "content3") })); final ParentEntity pdo = new ParentEntity(9, Collections.unmodifiableSet(col1)); em.getTransaction().begin(); em.persist(pdo); em.getTransaction().commit(); final Set<CollectedEntity> col2 = new HashSet<CollectedEntity>( Arrays.asList(new CollectedEntity[] { new CollectedEntity("label1", "content1"), new CollectedEntity("label2", "content2") })); final ParentEntity newEntity = new ParentEntity(pdo.getId(), col2); try { em.getTransaction().begin(); //Failure would occur on merge with EclipseLink construction and execution of DELETE statement em.merge(newEntity); em.getTransaction().commit(); } catch (final Exception e) { ... } Exception: Exception [EclipseLink-4002] (Eclipse Persistence Services - 3.0.0.qualifier): org.eclipse.persistence.exceptions.DatabaseException Internal Exception: java.sql.SQLSyntaxErrorException: ORA-00932: inconsistent datatypes: expected - got CLOB
Problem conclusion
The fix for this APAR changes the EclipseLink implementation and involves an update to the thirdparty source. See https://bugs.eclipse.org/bugs/show_bug.cgi?id=529602 The fix for this APAR is currently targeted for inclusion in Service Level (Fix Pack) 9.0.0.9 of WebSphere Application Server version 9.0 and in fix pack 18.0.0.2 for WebSphere Application Server Liberty.
