You are saying you are trying to connect to an SQL server but using a Microsoft Access Driver.您是说您正在尝试连接到 SQL 服务器，但使用的是 Microsoft Access 驱动程序。 Only use a Microsoft Access Driver if connecting to an Access Database/File.如果连接到 Access 数据库/文件，则仅使用 Microsoft Access 驱动程序。
Try the following, this is why I use to connect to a Microsoft SQL Server: sql_connection = pyodbc.connect('DRIVER={SQL Server};SERVER=IPADDRESS\\SQLSERVERINSTANCE;DATABASE=DBNAME;UID=USERNAME;PWD=PASSWORD;Trusted_Connection=no;')尝试以下操作，这就是我用来连接 Microsoft SQL Server 的原因： sql_connection = pyodbc.connect('DRIVER={SQL Server};SERVER=IPADDRESS\\SQLSERVERINSTANCE;DATABASE=DBNAME;UID=USERNAME;PWD=PASSWORD;Trusted_Connection=no;')
Microsoft have a doc on setting up pyodbc for Microsoft SQL Server: https://docs.microsoft.com/en-us/sql/connect/python/pyodbc/python-sql-driver-pyodbc?view=sql-server-ver15 Microsoft 有关于为 Microsoft SQL Server 设置 pyodbc 的文档： https ://docs.microsoft.com/en-us/sql/connect/python/pyodbc/python-sql-driver-pyodbc?view = sql-server-ver15
