[jira] Created: (OPENJPA-275) Bulk updates: version information should be automatically maintained when the query does not

Bulk updates: version information should be automatically maintained when the query does not
--------------------------------------------------------------------------------------------

                 Key: OPENJPA-275
                 URL: https://issues.apache.org/jira/browse/OPENJPA-275
             Project: OpenJPA
          Issue Type: Improvement
          Components: jdbc, query
    Affects Versions: 0.9.7, 0.9.6, 0.9.0
            Reporter: Patrick Linskey
            Assignee: Patrick Linskey
             Fix For: 1.0.0


According to the JPA specification, the user must manually maintain the @Version column in objects that are updated via a bulk update. This is a potential bug in the waiting, and is impossible to do correctly for time-based version fields.

OpenJPA should automatically increment version counters when a bulk update is issued that does not maintain version counters itself.

Of course, this will not change the fact that bulk updates do not do any optimistic lock checks; that behavior is inherent to the nature of bulk updates in the JPA specification, since they are evaluated entirely against the database.
