SQL Server Native Client (often abbreviated SNAC) was included in SQL Server 2005 through 2012. SQL Server Native Client was a stand-alone library that is used for both OLE DB and ODBC. After SQL Server 2012, the Microsoft ODBC Driver for SQL Server is the driver that is updated with the most recent server features going forward. This driver also isn't recommended for new development. Starting in SQL Server 2005, the SQL Server Native Client includes an ODBC interface and is the ODBC driver that shipped with SQL Server 2005 through SQL Server 2012. This driver isn't recommended for new development. The first 'SQL Server' ODBC driver still ships as part of Windows Data Access Components. There are three distinct generations of Microsoft ODBC drivers for SQL Server. This page describes Microsoft's historical data connection technologies for connecting to SQL Server.
