.NET ODBC Data Provider - Mailing list pgsql-odbc

As I mentioned in an earlier message, I've been playing with C# & .NET. In
.NET, unlike ADO it is possible to write your own INSERT/UPDATE/DELETE
parameterised queries to handle updates to a DataSet - if you do, then you
have a 'dynamic recordset', otherwise it's a very lightweight data cache (or
somewhere in between). An OdbcCommandBuilder object can be used to
auto-generate the queries from the SELECT as ADO does.

I'm having a problem persuading the an OdbcCommandBuilder object to generate
queries from a SELECT query - basically it just fails silently. Hunting
around on Google, others have reported the same problem with Foxpro where it
was put down to problems with the ODBC *and* OLE DB drivers.

I have tried both the release driver, and experimental ODBC3 driver - a
commlog from the latter is included below. Any help would be appreciated.

Regards, Dave.
