Subject [jira] Created: (DERBY-4259) Provide public database property for determining database format version
Date Thu, 04 Jun 2009 22:11:07 GMT
Provide public database property for determining database format version
------------------------------------------------------------------------

                 Key: DERBY-4259
                 URL: https://issues.apache.org/jira/browse/DERBY-4259
             Project: Derby
          Issue Type: Improvement
          Components: Services
    Affects Versions: 10.6.0.0
            Reporter: Kathey Marsden
            Priority: Minor


It would be useful  to have a public interface for determining the database format when running
in soft upgrade mode.  In the derby-user thread:
http://www.nabble.com/Hard-upgrade-failing--td23826558.html#a23835534
Evan pointed out he was using an undocumented property 'DataDictionaryVersion' for this purpose,
but this is not ideal because it does not conform to the normal derby.* naming convention
 and is not documented.

Discussion in DERBY-4255 determined that there are not currently DatabaseMetaData methods
that achieve the same result.
