Subject [jira] Updated: (DERBY-655) getImportedKeys returns duplicate rows in some cases
Date Wed, 31 May 2006 04:46:31 GMT
     [ http://issues.apache.org/jira/browse/DERBY-655?page=all ]

Mamta A. Satoor updated DERBY-655:
----------------------------------

    Attachment: Derby655GetImportedKeysPatch2Codeline101.txt

After submitting my earlier patch for 10.1, I ran the derbyall and found that there are few
more masters that are getting impacted by changes to metadata_test.java. So, I am attaching
a new diff file for 10.1 codeline, named Derby655GetImportedKeysPatch2Codeline101.txt(Commiters,
please disregard Derby655GetImportedKeysPatch1Codeline101.txt)

> 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.
