Most databases use vendor-specific types. Their treatment (even if it is: ignore these columns) has to be specified. That's why I specified this mapping first through its type [1]. Then I then gave a sense of the intended behavior [2]. I'll be happy to update [2] if I know which types we want to put there. Alexandre.
