Sql server UnixODBC、FreeTDS和PyODBC有问题
我很难让这三者协调工作。我想我会列出所有不同的配置,以及测试代码,看看是否有一双新鲜的眼睛可以意识到我的愚蠢 我正在运行12.04 Ubuntu服务器,我正在尝试连接到MSSQL Server 2008,并最终将其与PyODBC一起使用 但是,刚投入的时候,Sql server UnixODBC、FreeTDS和PyODBC有问题,sql-server,ubuntu,pyodbc,freetds,unixodbc,Sql Server,Ubuntu,Pyodbc,Freetds,Unixodbc,我很难让这三者协调工作。我想我会列出所有不同的配置,以及测试代码,看看是否有一双新鲜的眼睛可以意识到我的愚蠢 我正在运行12.04 Ubuntu服务器,我正在尝试连接到MSSQL Server 2008,并最终将其与PyODBC一起使用 但是,刚投入的时候, tsql -S T2 -U Foo -P Bar 我明白了 1> 2> 3> 4> 5> 6> 7> 8> 9> 10> 11> 等等 无论如何,如果有人能帮我(如果你能

我的Python测试文件只是为了更好的衡量

哇!这也许是我读过的关于堆栈溢出的最完整的答案。对我来说唯一的改变是在/etc/odbcinst.ini:/usr/lib/x86_64-linux-gnu/odbc/libtdsodbc.som中更改64位的位置,这是迄今为止最完整的答案!唯一缺少的是pyodbc的连接字符串
