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
