NP Property

未來的 Microsoft SQL Server 版本將移除這項功能。請避免在新的開發工作中使用這項功能，並規劃修改目前使用這項功能的應用程式。

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

語法

object.NP [= value]

Parts

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

• value
  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);

備註

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.

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

[!附註]

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.
