ODBC API Implementation Details
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.
This section documents the ODBC functions that exhibit SQL Server-specific behaviors when used with the SQL Server Native Client ODBC driver. Not all ODBC functions are documented here. The individual topics only discuss the SQL Server-specific issues for an ODBC function. They are not a complete reference for the ODBC functions.
The SQL Server Native Client ODBC driver complies with the ODBC 3.51 specification and, if you are using the Windows 7 SDK, with the ODBC 3.8 specification. For a comprehensive ODBC reference, view the ODBC Programmer's Reference online.
