NP Property

В будущей версии Microsoft SQL Server эта возможность будет удалена. Избегайте использования этой возможности в новых разработках и запланируйте изменение существующих приложений, в которых она применяется.

The NP property specifies the pipe name when using named pipe protocol on an instance of Microsoft SQL Server.

.NP [= value]

Parts

  • object
    An expression that evaluates to an object in the Applies To list

  • value
    A string that specifies the pipe name

String

Modifiable

Read/write

Prototype (C/C++)

HRESULT GetNP(SQLDMO_LPBSTR pRetVal);
HRESULT SetNP(SQLDMO_LPCSTR NewValue);

Замечания

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.

Важное примечаниеВажно!

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

ПримечаниеПримечание

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.
