Problem description
===================
As the specification says the getTableName method should return empty
string in case if no table name is available. Now it returns *null*

} catch (SQLException e) {
System.out.println( "Unexpected (0) "+e );
}
try {
String output = meta.getTableName(2);
System.out.println("output: "+output);
} catch (SQLException e) {
System.out.println( "Unexpected "+e );

System.out.println( "finished" );
