sql-server - 连接到 SQL Server 2014 的 FreeTDS 错误

Question

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是无效的。

查看错误日志并基于 Choosing TDS protocol ，是否支持 SQL Server 2014？

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

查看 tsql 转储的日志:

Answer 1

我不确定 SQL 服务器是否应该返回 TDS header ，如 HTTP/1.1 - 看起来您正在尝试连接到 Web 服务器(和/或错误的端口)。
