> Forward-only result sets that are exhausted should be implicitly
> closed on the server. This way, ResultSet.close() does not have to
> send an explicit close message generating unnecessary network traffic.
> The DRDA protocol supports this. From the description of OPNQRY (open
> query):
>   The qryclsimp parameter controls whether the target server
>   implicitly closes a non-scrollable query upon end of data (SQLSTATE
>   02000) in association with the cursor type.
