【问题描述】：

早上好！

我在运行命令时遇到问题：

tsql -S "servername" - U "user" -P "password"

我得到命令的响应：

There was a problem connecting to the server

我正在尝试连接到 MS SQL 服务器。我已经检查了文档，但我还没有找到解决这个问题的方法。

我的 freetds.conf 是：

[global]
    # TDS protocol version
    tds version = 4.2

    # Whether to write a TDSDUMP file for diagnostic purposes
    # (setting this to /tmp is insecure on a multi-user system)
    dump file = /tmp/freetds.log
    debug flags = 0xffff

    # Command and connection timeouts
    timeout = 10
    connect timeout = 10

    # If you get out-of-memory errors, it may mean that your client
    # is trying to allocate a huge buffer for a TEXT field.
    # Try setting 'text size' to a more reasonable limit
    text size = 64512

# A typical Sybase server
[egServer50]
    host = symachine.domain.com
        port = 5000
        tds version = 5.0

# A typical Microsoft server
[egServer70]
    host = ntmachine.domain.com
        port = 1433
        tds version = 7.0

[SRVBD1] 
        host = 10.7.1.7          
        instance = SQL2008
        port = 1434
        tds version = 5.0

检查 FreeTDS 日志文件我注意到以下错误：

有人知道怎么解决吗？

谢谢！

【问题讨论】：

您的示例显示- U（破折号和U之间的空格）；尝试删除空间；还是在创建您的问题时这是一个错字？当您将服务器/用户/密码用引号括起来时，tsql 是否正常工作？

【解决方案1】：

如果您的配置使用tds version = 5.0，SQL Server 2008 不支持。您可以尝试使用tds version = 7.1 代替吗？另外，你确定它在端口1434 而不是1433（默认）？

如果这不起作用，我会在解决问题时修改此答案，但这是我看到的第一个答案。
