我想在Ubuntu 14.04上使用FreeBSD连接到Windows SQL Server。 FreeTDS使用apt-get安装。 我尝试了以下命令的不同tds版本:
$ TDSVER=7.0 tsql -H xxx.xxx.xxx.xxx -U xxxx -p 1433 -P xxxxxxx
日志文件显示:
...
net.c:205:Connecting to xxx.xxx.xxx.xxx port 1433 (TDS version 7.0)
net.c:270:tds_open_socket: connect(2) returned "Operation now in progress"
net.c:310:tds_open_socket() succeeded
...
这里没问题。但是,如果我将TDSVER更改为7.4:
$ TDSVER=7.4 tsql -H xxx.xxx.xxx.xxx -U xxxx -p 1433 -P xxxxxxx
TDS版本变为4.2?
...
net.c:205:Connecting to xxx.xxx.xxx.xxx port 1433 (TDS version 4.2)
net.c:270:tds_open_socket: connect(2) returned "Operation now in progress"
net.c:310:tds_open_socket() succeeded
...
命令$ tsql -C
的输出是:
Compile-time settings (established with the "configure" script)
Version: freetds v0.91
freetds.conf directory: /etc/freetds
MS db-lib source compatibility: no
Sybase binary compatibility: yes

TDS version: 4.2
iODBC: no
unixodbc: yes
SSPI "trusted" logins: no

我尝试在〜/ .freetds.conf中配置tds版本,结果是一样的。
然后我尝试构建从git下载的版本并安装在我的主文件夹下。似乎版本匹配:
$ TDSVER=7.4 .local/bin/tsql -H xxx.xxx.xxx.xxx -U xxxx -p 1433 -P xxxxxxx
...
iconv.c:384:tds_iconv_open: done
net.c:216:Connecting to xxx.xxx.xxx.xxx port 1433 (TDS version 7.4)
net.c:242:tds_open_socket: connect(2) returned "Operation now in progress"
net.c:343:tds_open_socket() succeeded
...
$ .local/bin/tsql -C
的输出是:

这是v0.91的错误还是我做错了什么? 感谢。
答案 0 :(得分:3)
FreeTDS 0.91不支持TDS版本7.4。我有一个拉取请求,希望在文档中更清楚地说明这一点:
https://github.com/FreeTDS/freetds/pull/71/files
7.3
7.2
8.0
此外,从不使用7.0
,除非您使用非常旧版本的FreeTDS(此时您不应该使用此版本)。这是一个长篇故事,也包含在文档中,但网络上有很多“指南”推荐它。它将恢复为版本{{1}}并可能会产生问题。
