Mamta A. Satoor resolved DERBY-655:
-----------------------------------
Fix Version: 10.2.0.0
Resolution: Fixed
Resolving this issue since the patch ensures the uniqueness of conglomerateid
for new conglomerates in SYSCONGLOMERATES table. For existing duplicate
conglomeratid, work needs to be done at the database upgrade time. DERBY-1343
is open to track upgrade work. As per my knowledge, nobody is working on
DERBY-1343 at this point.
> getImportedKeys returns duplicate rows in some cases

> I have a database with a large number of tables. I get duplicate rows when I
> call DatabaseMetaData.getImportedKeys for a particular table. However, if I
> create the same table with same number of foreign keys in another database
> (which has fewer number of tables), then getImportedKeys returns me the
> correct number of rows. This error seems to happen only when the database has
> a large number of tables. I will attach a repro for this shortly.
