HRESULT GetNP(SQLDMO_LPBSTR pRetVal);

备注

Named pipe support is required on instances of SQL Server that run on Microsoft Windows. By default, SQL Server listens on the standard pipe, \\.\pipe\sql\query, for Named Pipes Net-Library connections. After SQL Server is installed, you can change the pipe name. You can also drop named pipe support and set SQL Server to listen only on other Net-Libraries.

To set the NP property, you must be a member of the sysadmin fixed server role.

重要提示：
Setting the NP property changes registry settings, and it should be used with caution.

注意：
If an application calls NP on an instance of SQL Server version 7.0, the constant, SQLDMO_E_SQL80ONLY, and the message "This property or method requires Microsoft SQL Server 2000 or later" are returned.
