Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server V6.1.0 Feature Pack for Enterprise * * JavaBeans 3.0 who make use of an * * @VersionStrategy of * * RowChangeTimestampStrategy. * **************************************************************** * PROBLEM DESCRIPTION: Incorrect SQL is generated when an * * @VersionStrategy of * * RowChangeTimestampStrategy is used. * **************************************************************** * RECOMMENDATION: * **************************************************************** There exists the potential for incorrect SQL to be generated when your JPA entity uses an @VersionStrategy of 'com.ibm.websphere.persistence.RowChangeTimestampStrategy'. For example, take the following JPA Entity definition: @Entity @VersionStrategy("com.ibm.websphere.persistence. RowChangeTimestampStrategy") public class ChildEntity implements Serializable { ..... @Id int id; @Version private Timestamp lupdDatetime; ..... The incorrectly SQL generating is missing your schema name. For example, if you specify a schema name via the "openjpa.jdbc.Schema" property of say 'mySchema'. In this case, SQL generated for CRUD operations on the field 'lupdDatetime' will not contain the schema name of 'mySchema'.
Problem conclusion
With this fix, code has been added to ensure that the proper SQL is generated when an entity uses 'com.ibm.websphere.persistence.RowChangeTimestampStrategy' as a VersionStrategy. The fix for this APAR is currently targeted for inclusion in Enterprise JavaBeans 3.0 Feature Pack Fix Pack 47 (6.1.0.47) of WebSphere Application Server version 6.1.0.
