  ****************************************************************
  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 Service Levels (Fix Packs) 7.0.0.25, 8.0.0.5, and
  8.5.0.1 of WebSphere Application Server versions 7.0.0,
  8.0.0, and 8.5.0.
