Python pymssql：Adaptive Server 连接失败

Question

我尝试使用 python 连接 Azure SQL，但出现下一个错误：

File "pymssql.pyx", line 641, in pymssql.connect (pymssql.c:10824)
pymssql.OperationalError: (20002, 'DB-Lib error message 20002, severity 9:\nAdaptive Server connection failed (myserver:1433)\n')

freetds.conf:

[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

如果我尝试连接使用 tsql - 连接成功！

我尝试使用参数重新编译 freetds：

./configure --enable-msdblib --enable-threadsafe --enable-sybase-compat --with-tdsver=7.4 --with-openssl=/usr/bin

我正在使用这本手册https://msdn.microsoft.com/en-us/library/mt694094(v=sql.1).aspx

Answer 1

@Alximik 根据我的经验，我认为没有必要自行重新编译 freetds。对于这个问题，我认为问题是由您对 freetds.conf 的配置引起的，请参阅我对已解决的 SO 线程的回答和下面的示例配置内容。

host = <database_name>.database.windows.net
port = 1433
tds version = 7.3

同时，您可以参考http://www.freetds.org/userguide/freetdsconf.htm进行配置

Answer 2

我在从源代码 pymssql 和 freetds 生成后解决了它（使用先前 post 中的选项并在全局配置中设置 tds version=7.3）。 Pymssql make from source use command "python setup.py build" 然后下一步在系统中安装 "python setup.py install"
