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.
