如前所述，使用 SQL Server 2000 是一个 真的 坏主意；它没有收到任何支持、错误修复，或者最重要的是，来自 Microsoft 的安全补丁。
就是说，如果您使用的是 django-pyodbc-azure，您也许可以对其进行猴子修补以使其正常工作。看到这一行：
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 词典中：
_sql_server_versions = {
8: 2000,
9: 2005,
10: 2008,
11: 2012,
12: 2014,
13: 2016,
14: 2017,
}
我无法保证这是否有效，但欢迎您尝试。这应该可以帮助您克服遇到的错误。
您还需要修改 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，我再次强烈建议升级到现代版本的 SQL 服务器。
