I just found

The BizTalk Utilities Adapter for Databases allows BizTalk Server 2004/2006 to interact with any .NET Compliant Data Provider.

Support for the following .NET Data Providers are provided by default:

* Microsoft .NET SQL Server Data Provider
* Microsoft .NET Oracle Data Provider
* Microsoft .NET OLEDB Data Provider
* Microsoft .NET ODBC Data Provider
* IBM DB2 .NET Data Provider
* IBM DB2 UDB for iSeries .NET Provider
* Sybase ASE .NET Data Provider
* PgSqlClient .NET Data Provider (PostgreSql)
* MySql .NET Data Provider
* FireBird ADO.NET Data Provider
* Oracle Data Provider for .NET (ODP)
* Microsoft Host Integration Server OLEDB Interface

Data providers can be extended by simply adding a new provider definition.

Will have a try tongiht, but wonder if anyone used it before? How good is it?
