For more information about the use of these features with ADO, see Using ADO with SQL Native Client. When using the SQL Native Client OLE DB provider, ADO applications may exploit those new features of SQL Server 2005 that are available via the SQL Native Client via connection string keywords or OLE DB properties or Transact-SQL. 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 required).ĪctiveX Data Object (ADO) applications may use the SQL Native Client OLE DB provider, but it is recommended to use it in conjunction with the DataTypeCompatibility connection string keyword (or its corresponding DataSource property).

The SQL Native Client ODBC driver is always used in conjunction with the ODBC Driver Manager supplied with MDAC.

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.įor a list of the differences between SQL Native Client and MDAC, plus information about issues to consider before updating an MDAC application to SQL Native Client, see Updating an Application to SQL Native Client from MDAC. It combines the SQL OLE DB provider and the SQL ODBC driver into one native dynamic-link library (DLL) while also providing new functionality above and beyond that supplied by the Microsoft Data Access Components (MDAC). SQL Native Client is a data access technology that is new to Microsoft SQL Server 2005, and it is a stand-alone data access application programming interface (API) that is used for both OLE DB and ODBC. Transact-SQL endpoints create by SQL Server Setup are as follows:įor more information on managing Transact-SQL endpoints, see Net-Libraries, Network Protocols, and TDS Endpoints. The GRANT, REVOKE, and DENY ENDPOINT syntax uses an endpoint ID that the admin must get from the endpoint's catalog view. By default, all users have permissions to access an endpoint unless the permissions are denied or revoked by a member of the sysadmin group or by the endpoint owner. Permissions can be granted, revoked, and denied for Transact-SQL endpoints. SQL Server 2005 introduces a new concept for SQL Server connections the connection is represented on the server end by the concept of a Transact-SQL endpoint. Use the SQL Server 2005 Network Configuration area of the SQL Server Configuration Manager to enable, disable, and configure network protocols after Setup is complete. To enhance security, network connectivity is not fully enabled when SQL Server 2005 is installed. Choose a port in this range that is not used by the operating system or another application. If you cannot use dynamic port addresses (for example, when SQL Server connections must pass through a firewall server configured to pass through specific port addresses, or when some connections are made using the client components from SQL Server version 7.0 or earlier), then using a port address less than 1024 is recommended. This problem should not occur if the instance of SQL Server is configured to use a dynamic port address by specifying a port address of 0 using the SQL Server Configuration Manager.

The TCP/IP server Net-Library will not initialize, and the instance of SQL Server cannot accept TCP/IP connections until the service is stopped and restarted. When an instance of Microsoft SQL Server is configured to listen on a static IP port (such as a default instance that takes the default of listening on port 1433), the SQL Server service cannot open the port if another application or component is using the port when the SQL Server service initializes. After installation, you can change these configurations using the SQL Server Configuration Manager. If a particular Net-Library is not configured, the server cannot listen on that Net-Library. During installation, SQL Server 2005 Setup installs all of the Net-Libraries onto the computer and allows you to configure some or all of the Net-Libraries.

The network libraries, implemented as dynamic-link libraries (DLLs), perform the network operations required to communicate using specific interprocess communication (IPC) mechanisms.Ī server can listen on, or monitor, multiple network libraries at one time. Network libraries are used to pass network packets between clients and a server running SQL Server.
