试图运行 sqlcmd 失败，无法建立连接? [英] trying to run sqlcmd fails, unable to establish connection?

问题描述

当我尝试运行 sqlcmd(从 cmd 提示符)时，出现以下错误:

When I try to run sqlcmd (from the cmd prompt) I get the following error:

HResult 0x2，级别 16，状态 1命名管道提供程序:无法打开与 SQL Server [2] 的连接.Sqlcmd: 错误: Microsoft SQL Server Native Client 10.0 : A network-related or in与 SQL Server 建立连接时发生特定于立场的错误.服务器未找到或无法访问.检查实例名称是否正确，我f SQL Server 配置为允许远程连接.有关更多信息，请参阅SQL Server 联机丛书Sqlcmd:错误:Microsoft SQL Server Native Client 10.0:登录超时.

HResult 0x2, Level 16, State 1 Named Pipes Provider: Could not open a connection to SQL Server [2]. Sqlcmd: Error: Microsoft SQL Server Native Client 10.0 : A network-related or in stance-specific error has occurred while establishing a connection to SQL Server . Server is not found or not accessible. Check if instance name is correct and i f SQL Server is configured to allow remote connections. For more information see SQL Server Books Online.. Sqlcmd: Error: Microsoft SQL Server Native Client 10.0 : Login timeout expired.

不知道为什么会这样?我可以从我的 asp.net 网站(在本地运行，如数据库)连接到 sql 服务器，但 sqlcmd 无法连接.

Not sure why this happens? I can connect to the sql server from within my asp.net website (which runs locally, like the database) but sqlcmd can't connect.

推荐答案

Try sqlcmd -S

• 只有在您将服务器安装为默认实例时，您的命令才会起作用.
• 运行 sp_helpserver 以了解实例名称.
