Hey Bill,

  This is great news!!  I was one interested party that was great disappointed
to find out that FreeTDS did not have cursors available.  It hurt so much that
I had to scrap plans to use this driver and went to a commercial vendor.  I
would love to see this functionality be incorporated into the ODBC module as
well.  I am not up on the technical issues, but as a user, it would be good to
have multiple resultsets handled with a single connection.  The API I'm using
does not handle this and I'm not even sure that the commercial driver does
either.  The main reason I'm interested in this is simply one of speed.  We
deal in multiple connections with multiple machines all hitting one backend
DB.  It seems pointless to connect and dump the connection with every query we
need to run.  Connect times are typically the most expensive and it would
boost our throughput immensely to re-use the connection.
