Has anyone made any database connectivity tools publicly available? I
know that Mike Wallace has done a lot of work with the IDL-Java bridge
and JDBC but I don't think he has released anything. I have worked with
the ADODB COM object and plan to experiment with it in IDL this
afternoon but ideally someone will have already done this :)

My quest for database connectivity continues...
ADO + IDL's COM interface is a no go. Despite the work of Paul and
others, IDL's com interface is still not complete. It is unable to
properly return arrays of type variant containing mixed types nor is it
able (as best as I can tell) return arrays of arrays of type variant. I
will submit my feature request and hope for the best but I am not
holding breath.
Renaud, I have dropped you a couple of emails with no response so I will
try one last time by posting here. I would very much like to test
DataJiver. Please email me or post additional information.
