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.
SQLFetch supports enhanced date and time features.
For information about how result column values of date/time types are converted, see Conversions from SQL to C.
SQLFetch supports large CLR user-defined types (UDTs). For more information, see Large CLR User-Defined Types (ODBC).
