NP Property
This feature will be removed in a future version of Microsoft SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature.
The NP property specifies the pipe name when using named pipe protocol on an instance of Microsoft SQL Server.
Syntax
object.NP [= value]
Parts
object
An expression that evaluates to an object in the Applies To listvalue
A string that specifies the pipe name
Data Type
String
Modifiable
Read/write
Prototype (C/C++)
HRESULT GetNP(SQLDMO_LPBSTR pRetVal);
HRESULT SetNP(SQLDMO_LPCSTR NewValue);
Remarks
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.
Important
Setting the NP property changes registry settings, and it should be used with caution.
Note
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.
