SQL Server Native Client (ODBC) Reference
Open Database Connectivity (ODBC) is a Microsoft Win32 application programming interface used by applications to access data in ODBC data sources.
The SQL Server Native Client ODBC driver reference does not document all of the ODBC function calls. Only those functions that have driver-specific parameters or behaviors when used with the SQL Server Native Client ODBC driver are discussed.
The SQL Server Native Client ODBC driver complies with the ODBC 3.51 specification. For a comprehensive reference of ODBC 3.51, download the Microsoft Data Access Components SDK from the Data Access and Storage Developer Center, or view the ODBC Programmer's Reference online.
