NP Property
Questa caratteristica verrà rimossa a partire da una delle prossime versioni di Microsoft SQL Server. Evitare di utilizzare questa funzionalità in un nuovo progetto di sviluppo e prevedere interventi di modifica nelle applicazioni in cui è attualmente implementata.
The NP property specifies the pipe name when using named pipe protocol on an instance of Microsoft SQL Server.

Osservazioni
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.

Setting the NP property changes registry settings, and it should be used with caution. |
[!NOTA]
If an application calls NPon 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.
