Not all drivers support scrollable cursors, which means that
rs.moveFirst (and moveLast and movePrevious) would not be supported.
Your best best is to assume forward-only cursors, and only use
rs.moveNext.
You do not need to call rs.moveFirst after executing a query - the
cursor is placed at the first row by default.

Jonathan, Martin,
Thanks for the advice, however I still can only see the first record in the recordset. I am very frustrated at this point. I see that this support request for last year has not been resolve, and it appears to be the same problem:
http://sourceforge.net/tracker/index.php?func=detail&aid=1681056&group_id=177561&atid=881727
I was thinking that what I am trying to do was quite common (MySQL DB using ODBC), and hoping I could leverage what someone else has already learned.
I would really like to get this working using ODBC rather than being limited to a particular DB, even if ODBCKit doesn't work and/or is no longer supported.
Again, thanks,
Matt
