s:df_append.to_sql（'FFIEC_CDR_Call_Schedule_RIBII'，con=engine，if_exists='append'）我得到这个错误：OperationalError:（sqlite3.OperationalError）table FFIEC_CDR_Call_Schedule_RIBII没有名为index的列，肯定有一个名为index的字段，但我不知道为什么需要它，因为它肯定不是字段。无论如何，我也尝试了以下方法：engine=create\u engine（cnxn，fast\u executemany=True）df\u append.to\u sql（'FFIEC\u CDR\u Call\u Schedule\u RIBII'，engine，index=False，如果存在，'append'）这给了我这个错误：AttributeError:'pyodbc.Connection'对象没有属性'\u实例化\u插件'如果不将pyodbc.Connection对象传递给

create\u engine（）

，则传递一个SQLAlchemy连接URI（字符串），SQLAlchemy为您创建DBAPI连接。再次检查。提示：您可以使用SQLAlchemy使用现有的pyodbc连接字符串。谢谢Gord。1433的TCP/IP端口已禁用。那没用。终于让它运行了，有了这个：engine=“mssql+pyodbc://Server_Name/DB_Name?driver=SQL 服务器本机客户端11.0？受信任的\u连接=是”
