The unixODBC cursor lib is only half finished, however I have been looking for
a excuse to finish it, part of the problem was finding someone to test what
I had done. before that could you install unixODBC-1.8.3.

What is the application ? Have you source I could take at ?

Could you send a trace from the odbc log (add the following to your
odbcinst.ini)

[ODBC]
Trace = yes
Trace File = /tmp/sql.log

and send me the /tmp/sql.log file.

If you dont mind a bit of debugging, we should be able to sort this out.
