Hi friends! I thought of sharing this URL with you all where I usually get information about connection strings. This has been a reference site for me on various connection strings for several years now. It's a great site where it gives a collection of connection strings for most of the databases servers, data files and other data sources in one place. And it gives connection strings for different scenarios (ODBC, OLE DB etc) for the same data source as well.
Check it out.
