freetds 无法识别任何配置文件中的版本

Question

不知道为什么...

我在 /etc/freetds/freetds.conf、/usr/share/freetds/freetds.conf 和 ~/.freetds.conf

中有相同的 conf 文件

#   $Id: freetds.conf,v 1.12 2007/12/25 06:02:36 jklowden Exp $
#
# This file is installed by FreeTDS if no file by the same 
# name is found in the installation directory.  
#
# For information about the layout of this file and its settings, 
# see the freetds.conf manpage "man freetds.conf".  

# Global settings are overridden by those in a database
# server specific section
[global]
        # TDS protocol version
    tds version = 7.4

    # 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

[cdcods]
    host = *my_host*
    port = 1433
    tds version = 7.4

其中 my_host 是我实际的 mssql 主机。我正在连接到 MSSQL 2012，所以我认为 7.4 是正确的。

我使用的命令是$tsql -S cdcods -U 'my_domain\my_user' -P 'my_pass'

这是日志：

Answer 1

您是运行 FreeTDS v0.91，不支持 TDS 7.4 版。 IIRC它支持的最高是7.2。正在尝试使用 7.2 版。

如果您想使用 TDS 版本 7.3，您至少需要 FreeTDS 0.95，如果您想要 7.4，您需要 FreeTDS 1.0。

我有一个 PR 来澄清这一点，但它还没有被推送到文档中。

祝你好运！
