Description

DB2 is another DBMS in which clients must connect to a named database, not just to the DBMS. A JDBC connection that does the same will receive a single record containing a null string from a call to Connection::getMetaData::getCatalogs. We need to ignore such a record in order to query DB2 correctly.
