python pyodbc-在windows/python2.7上连接到sql server 2008，但在centOS6.32/python2.6.6上不连接

我有以下代码：

import pyodbc

cnxn = pyodbc.connect("DRIVER={SQL Server};"
                      +"SERVER=something.example.com;"
                      +"DATABASE=something;")

cursor = cnxn.cursor()

name=('Smith, Joe', )

cursor.execute('SELECT id FROM Users WHERE displayname=?', name)
rows = cursor.fetchall()

for row in rows:
        print row

代码在windows/python2.7上按需要执行。但是，当我尝试在linux上运行它时，出现以下错误：

Traceback (most recent call last):
  File "/something/script.py", line 125, in <module>
    main()
  File "/something/script.py", line 77, in main
    +"DATABASE=something;")
pyodbc.Error: ('IM002', '[IM002] [unixODBC][Driver Manager]Data source name not found, and no default driver specified (0) (SQLDriverConnectW)')

您没有为sql server配置odbc驱动程序-您需要安装并配置一个。的网页上的驱动程序部分建议，或者你也可以试试微软自己的

freedts应该可以使用

yum安装

然后，基本配置应如下所示：

/etc/odbcinst.ini
：

[SQL Server]
Description=SQL Server的FreeTDS驱动程序
Driver=/usr/lib/libtdsodbc.so
Driver64=/usr/lib64/libtdsodbc.so

现在你应该已经可以连接了。有关配置的更多详细信息，请参阅

编辑：

或者，还有其他从python连接到sql server的方法，如和
请发布
odbcinst.ini
文件的内容。
