连接到 SQL Server 2014 的 FreeTDS 错误

问题描述

我已经尝试了从 4.2 到 7.2 的所有可用版本，在我看来，我尝试过的所有版本都无效.

I have tried all the version available from 4.2 until 7.2, it seems to me all the versions I've tried are invalid.

查看错误日志并根据选择TDS协议，是SQL服务器2014 支持吗?

Looking at the errors logs and based on the Choosing TDS protocol, is SQL server 2014 supported?

简要错误:

Error 20017 (severity 9):
    Unexpected EOF from the server
    OS error 115, "Operation now in progress"
Error 20002 (severity 9):
    Adaptive Server connection failed

推荐答案

我不确定 SQL 服务器是否应该像 HTTP/1.1 一样返回 TDS 标头 - 看起来您正在尝试连接到Web 服务器(和/或错误的端口).

I'm not that sure that SQL server should return TDS header like HTTP/1.1 - looks like you are attempting to connect to web server (and/or wrong port).
