Frequently asked questions about SQL Native Client
Q1: What is SQL Native Client?
A1: Microsoft SQL Server Native Client (SQL Native Client) contains the SQL OLE DB provider and SQL ODBC driver in one native dynamic link library (DLL) supporting applications using native-code APIs (ODBC, OLE DB and ADO) to Microsoft SQL Server. SQL Native Client should be used rather than Microsoft Data Access Components (MDAC) to create new applications or enhance existing applications that need to take advantage of new SQL Server 2005 features such as Multiple Active Result Sets (MARS), Query Notifications, User-Defined Types (UDT), and XML data type support.
Q2: What versions of SQL Server does SQL Native Client support?
A2: SQL Native Client supports Microsoft SQL Server 7.0, 2000 and SQL Server 2005.
Q3: Why would I move from MDAC (either the SQL ODBC driver or the SQL OLEDB provider)?
A3: SQL Native Client can be used to create new applications or enhance existing applications that need to take advantage of new SQL Server 2005 features such as Multiple Active Result Sets (MARS), user-defined data types (UDT), query notifications, snapshot isolation, and XML data type support.
Q4: Where can I find documentation for SQL Native Client?
A4: SQL Native Client documentation is available in the “SQL Server Programming Reference” section of the SQL Server 2005 Books Online. SQL Server 2005 Books Online can be viewed in the MSDN Library, available for download on
http://www.microsoft.com/downloads and is optionally installed with Microsoft SQL Server 2005.
Q5: Does SQL Native Client require MDAC and if so what version?
A5: The SQL Native Client ODBC driver is always used in conjunction with the ODBC Driver Manager supplied with MDAC. The SQL Native Client OLE DB provider may be used in conjunction with OLE DB Core Services supplied with MDAC, but this is not a requirement – the choice to use Core Services or not depends on the requirements of the individual application (for example, if connection pooling is required). SQL Native Client uses the version of MDAC supplied by the operating system.
