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.

Setting the NP property changes registry settings, and it should be used with caution.
ms136316.note(zh-cn,SQL.90).gif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.
