我正在使用Django和PyODBC连接到SQL Server 2000数据库，我得到了这个错误：
异常类型： 未实现错误
异常值：不支持 SQL Server v8。

我的 odbc.ini：

Port = 1433
Database = database
Driver = /usr/local/lib/libtdsodbc.so

My freetds.conf
[HGP]
database = database
host = "IP"
port = 1433
tds version = 8.0
odbcinst.int 上的驱动程序配置
[FREETDS]
Description = FreeTDS
Driver = /usr/lib/i386-linux-gnu/odbc/libtdsodbc.so
Setup = /usr/lib/i386-linux-gnu/odbc/libtdsS.so

我的 settings.py
'hgp': {
'ENGINE': 'sql_server.pyodbc', # Add 'postgresql_psycopg2', 'postgresql', 'mysql', 'sqlite3' or 'oracle'.

我的查询

如前所述，使用 SQL Server 2000 是一个非常糟糕的主意;它不会从Microsoft获得任何支持、错误修复，或者最重要的是安全补丁。
也就是说，如果您使用的是 django-pyodbc-azure ，您也许可以对它进行猴子修补以使其正常工作。请参阅此行：
https://github.com/michiya/django-pyodbc-azure/blob/azure-1.10/sql_server/pyodbc/base.py#L145
将8: 2000,添加到_sql_server_version字典：
_sql_server_versions = {
8: 2000,
9: 2005,
10: 2008,
11: 2012,
12: 2014,
13: 2016,
14: 2017,
}
我不能保证这将如何工作，但欢迎您尝试。这应该可以让您克服遇到的错误。
您还需要修改您的freetds.conf，因为8.0不是有效的 TDS 版本：
[HGP]
database = database
host = "IP"
port = 1433
tds version = 7.1

祝你好运，再次，我强烈建议升级到现代版本的SQL Server。
