Question

摘要：：tsql连接而isql未连接。

详细信息：我已经尝试了所有可以找到的官方安装指南和Stack Overflow问题，但没有一个能让人高兴。我正在尝试使用pyodbc从我的Mac（Mohave）和最终的Xubuntu 16.04虚拟机连接到MS SQL Server数据库。在进入Python之前，我只想对连接进行故障排除。问题是，我看到的大多数文档都缺少重要的细节，例如“我应该在用户名和密码中使用引号吗？”。或者，“我应该在用户名中包含域吗？”如果我应该在域中添加用户名，“我是否应该转义反斜杠字符？”

这是我当前的设置：tsql -C产生

Compile-time settings (established with the "configure" script)
                            Version: freetds v1.1.11
             freetds.conf directory: /usr/local/etc
     MS db-lib source compatibility: no
        Sybase binary compatibility: yes
                      Thread safety: yes
                      iconv library: yes
                        TDS version: 7.3
                              iODBC: no
                           unixodbc: yes
              SSPI "trusted" logins: no
                           Kerberos: yes
                            OpenSSL: yes
                             GnuTLS: no
                               MARS: yes

/usr/local/etc/freetds.conf的内容是：

#
# 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 = auto

    # 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

    # To reduce data sent from server for BLOBs (like TEXT or
    # IMAGE) try setting 'text size' to a reasonable limit
;   text size = 64512

    # If you experience TLS handshake errors and are using openssl,
    # try adjusting the cipher list (don't surround in double or single quotes)
    # openssl ciphers = HIGH:!SSLv2:!aNULL:-DH

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

# A typical Microsoft server
[egServer73]
    host = ntmachine.domain.com
    port = 1433
    tds version = 7.3

[my_server]
    host = my_server
    port = 1433
    tds version = 7.3

my_server是我要连接的服务器。命令tsql -S my_server -U domain\\username -P password（在任何地方都没有引号）可以很好地连接，并显示结果

locale is "en_US.UTF-8"
locale charset is "UTF-8"
using default charset "UTF-8"

FreeTDS太多了。对于ODBC方面，首先请注意，显然已经为ODBC设置了FreeTDS，因为它在unixodbc: yes的结果中显示了tsql -C。我的/etc/odbcinst.ini文件包含：

[FreeTDS]
Description=FreeTDS Driver for Linux & MSSQL
Driver=/usr/local/lib/libtdsodbc.so
Setup=/usr/local/lib/libtdsodbc.so
UsageCount=1

我的/etc/odbc.ini文件包含

[my_server]
Description = "The Location of the EOAM_RA Database"
Driver = FREETDS
Trace = Yes
TraceFile = /tmp/sql.log
Database = my_database
Servername = my_server
UserName = domain\\username
Password = password
Port = 1433
Protocol = 7.3
ReadOnly = No
RowVersioning = No
ShowSystemTables = No
ShowOidColumn = No
FakeOidIndex = No

但是，当我尝试使用任何版本的isql -v my_server username password时，我都会感到恐惧和无济于事

[S1000][unixODBC][FreeTDS][SQL Server]Unable to connect to data source
[01000][unixODBC][FreeTDS][SQL Server]Unknown host machine name.
[ISQL]ERROR: Could not SQLConnect

因此，尽管我当然希望对所有设置都具有正确的设置，以便我可以通过isql并最终通过pyodbc进行连接，但是如果我能得到以下答案的话，这也将大有帮助问题：

在每个应该输入用户名的地方，都应该在引号中加上引号吗？
在每个应该输入用户名的地方，都应该在域名前加上前缀吗？
对于每个我应该输入用户名的地方，如果我确实需要包括我的域，是否应该在中间输入反斜杠？
对于服务器，我应该加引号吗？

非常感谢您的光临！

在freetds.conf文件中为SQL Server使用完全限定的域名（fqdn）之后，您是否尝试过连接：

[my_server]
host = my_server.<yourdomain.example>
port = 1433
tds version = 7.3

在Mac上使用isql连接到MS SQL Server数据库
