what do you think about using an SQL-ODBC-driver (SQLSRV32.DLL) with the name 'SQL SERVER' for accessing a SQL Server 2008 Server database?
A first look shows that it works but is there something like upward combatibility?
If possible, I would get a current ODBC driver. I don't know what kind of backward compatibility SQL Server 2008 has been given for older ODBC drivers, so I would tread carefully.
What that means in practice is that if it works, great, but test the heck out of it. Don't rest assured that all is fine because you could connect and run a "select * from xxx" query. Test the app thoroughly; if you are updating, test the updates, and test summarization. Repeat the tests after patching or upgrading the server or making changes to the app.
