Rick Hillegas commented on DERBY-5818:
--------------------------------------

Hi Saurabh,

Thanks for explaining more about the problem. Adding DBMDWrapper to Derby will only help you
if the Derby code is at a rev level greater than 10.9.1. The SQL functions you need won't
be built into Derby in 10.8.2.2. If you could tolerate shipping DBMDWrapper with your application,
then you could get around this issue.

I'm not sure that I understand the problem completely, though. There are two version numbers
which you have to be concerned about when you use Derby:

1) The version level of derby.jar. This determines the capabilities of newly created databases.

2) The version level of your particular database. This could be lower than the version level
of newly created databases.

Because of soft-upgrade, it is possible that your derby.jar can be at version level 10.9.1
even though your database is still at version 10.2.1. Some 10.9.1 features and bug fixes will
be available in your database, but some won't. The ones which won't be available are the ones
which require changes to Derby metadata, stored in the database catalogs. That metadata is
only changed when you do a hard-upgrade, bringing your database version up to the version
of derby.jar.

Are you trying to discover the full version string for (1), (2), or both?

Thanks,
-Rick
