What's New in SQL Server Native Client

[!INCLUDEssSQL14] installs [!INCLUDEssSQL11] Native Client. There is no [!INCLUDEssSQL14] Native Client.

There will be no more updates to the ODBC driver in [!INCLUDEssNoVersion] Native Client. The successor to the ODBC driver in [!INCLUDEssNoVersion] Native Client, which is called the [!INCLUDEmsCoName] ODBC Driver 11 for [!INCLUDEssNoVersion] on Windows, is installed with [!INCLUDEssSQL14]. For more information about the [!INCLUDEmsCoName] ODBC Driver 11 for [!INCLUDEssNoVersion] on Windows, see Microsoft ODBC Driver 11 for SQL Server - Windows.

The OLE DB Provider in [!INCLUDEssNoVersion] Native Client was last updated in [!INCLUDEssSQL11] Native Client. Developers who wish to use an OLE DB provider to connect to the latest version of [!INCLUDEssNoVersion] must use the OLE DB provider that shipped in [!INCLUDEssSQL11] Native Client.

The following topics describe significant new [!INCLUDEssNoVersion] Native Client features in [!INCLUDEssSQL11].

• SQL Server Native Client Support for LocalDB

• Metadata Discovery

• UTF-16 Support in SQL Server Native Client 11.0

• SQL Server Native Client Support for High Availability, Disaster Recovery

• Accessing Diagnostic Information in the Extended Events Log

In addition, ODBC in [!INCLUDEssNoVersion] Native Client now supports three features that were added to standard ODBC in the Windows 7 SDK:

• Asynchronous execution on connection-related operations. For more information, see Asynchronous Execution.

• C Data Type Extensibility. For more information, see C Data Types in ODBC.

  To support this feature in [!INCLUDEssNoVersion] Native Client, SQLGetDescField can return SQL_C_SS_TIME2 (for time types) or SQL_C_SS_TIMESTAMPOFFSET (for datetimeoffset) instead of SQL_C_BINARY, if your application uses ODBC 3.8. For more information, see Data Type Support for ODBC Date and Time Improvements.

• Calling SQLGetData with a small buffer multiple times to retrieve a large parameter value. For more information, see Retrieving Output Parameters Using SQLGetData.

The following topics describe [!INCLUDEssNoVersion] Native Client behavior changes in [!INCLUDEssSQL11].

• When calling ICommandWithParameters::SetParameterInfo, the value passed to the pwszName parameter must be a valid identifier. For more information, see ICommandWithParameters.

• SQLDescribeParam will now consistently return a value that conforms to the ODBC specification. For more information, see SQLDescribeParam.

• ODBC Driver Behavior Change When Handling Character Conversions
