Dan Guzman discusses a couple deprecated components which are still hanging around:
The message is loud and clear that ODBC is the supported and preferred path for native applications going forward. The Data Access Technologies Road Map provides an overview and history of Microsoft data access technologies, which I recommend you peruse to ensure you are not inadvertently using deprecated or unsupported technologies for new development and, for existing applications, consider moving from legacy data access technologies to current ones when practical.
The current Microsoft ODBC Driver for SQL Server as of this writing is ODBC Driver 13 for SQL Server. Note that that both the 13.0 and 13.1 versions of this driver have the same “ODBC Driver 13 for SQL Server” display name listed under installed programs and ODBC Data Source Administrator. If installed, the driver will be listed under installed programs along with the corresponding driver version (when viewed detail mode). The 13.1 version adds support for the Always Encrypted feature. These ODBC Drivers are available from the link I mentioned earlier.
They will pry OLE DB from my cold, dead hands. For my money, it’s still the best SQL Server data access technology for Integration Services, beating out ODBC both in terms of ease of use and performance.
