ODBC How-to Topics
SQL Server Native Client (SNAC) is not supported beyond SQL Server 2012. Avoid using SNAC in new development work, and plan to modify applications that currently use it. The Microsoft ODBC Driver for SQL Server provides native connectivity from Windows to Microsoft SQL Server and Microsoft Azure SQL Database.
To use the SQL Server ODBC driver, you must be able to create ODBC data sources and ensure that the server has the correct version of the catalog stored procedures. To code an ODBC application that uses SQL Server, you must know how to allocate ODBC handles, set attributes, connect to an instance of SQL Server, execute queries, and process results.
