We have spent days trying to perform a proof of concept and I am
dissappointed with SSIS to say the least. We are trying to connect and
fetch data from a Double Byte Progress database and the "DataReader
Source" using a ADO .NET ODBC provider does not work! I understand
that SSIS is a totally rewritten version of DTS. What annoys me is
that this functionality used to work in DTS and does not in the much
talked about SSIS!! Will someone in Microsoft start listening to
customers instead of gloating on useless features. SSIS is a total
waste if it cannot connect and fetch data from a wide variety of
source databases!!

In my experience, ODBC is a bad choice. It is slower than dirt and
a very old technology. I use SSIS w/ an OLE DB driver (both DB2 and
SQL Server) and have been very impressed with its functionality.

Can you use an OLE DB driver?

As "aj" suggested, you could try OLE DB instead. There may not be an
OLE DB provider for your data source, but you should still be able
to use MSDASQL, OLE DB over ODBC.

OLE DB is an general API for communicating with databases that is COM-based.
It appeared on the scene around 1998, and for a while this was the top of
the pops. However, it never became the smashing success that Microsoft
intended.

The main difference between OLE DB and ODBC as general APIs is that ODBC
assumes that the data source is relational, OLE DB does not. So you
can use OLE DB to access text files or Active Directory. However, OLE DB
is a more complex API, and applications which uses the OLE DB API directly,
are likely to become very verbose.

Now, most applications that uses OLE DB, use some other high-level API,
like ADO. Or OleDB Client in .Net.

For a data source like SQL Server, OLE DB is very much alive. But for
many smaller data sources, no one ever came around to implement an
OLE DB provider, and apparently there is not one for Double Byte Progress
that you use.

However, the first OLE DB provider that saw the light of day was MSDASQL,
which implements the OLE DB API on top of ODBC. Which means that everyhing
that has an ODBC driver still can be accessed from OLE DB. Maybe not
optimally, but it can be accessed.

Currently you use OdbcClient in .Net and you have problems with it.
I'm not going to promise that MSDASQL will fare any better, but I think
you should give it a try. I've tried using OdbcClient with SQL Server
and that did not work well.

So in your SSIS package, try replacing the DataReader source with an
OLE DB Source, and, oops! As I actually looked into BIDS and found
my way to the Connection Manager, I find that MSDASQL is not listed.
Drat! There goes my theory.

That was quite a long reply for nothing.

I am going around in circles here, lodged a ticket with DataDirect

who in turn pointed me to QAD (ERP Application Provider) who is now

using this technology.

Thanks for your post though. If we cannot do this via SSIS, I
basically explore and recommend another ETL tool that would accomplish
this task.

You could try Pentaho Data Integration (http://kettle.pentaho.org/),
formerly known as Kettle. We have been able to query Progress
databases (version 10.0B) using the DataDirect ODBC driver. You could
also play around with the JDBC Progress driver if you want, though I
have had trouble getting it to work. Kettle is Open Source but very
well supported with a decent set of documentation.
