import pyodbc as po    

connection_string = """
driver=ODBC Driver 17 for SQL Server;
server=SHADOW-LN4F5NUO;
database=FBI_Crime_Data;
trusted_connection=True;
"""

connection = po.connect(connection_string)

输出:

• 服务器名称正确。
• 数据库名称正确
• 存在 ODBC 驱动程序。
• SSMS 中的 Windows 身份验证有效。

Answer 1

根据 this microsoft documentation ，可识别的值为 true、false、yes、no 和 sspi

pyodbc documentation说，您可以通过提供 Trusted_Connection 属性使用您的 Windows 帐户而不是用户名/密码进行身份验证:Trusted_Connection=yes

所以它看起来是 connectionstrings sql server main page向您显示 .Net 库的连接字符串。如果您单击“ODBC 驱动程序”下特定版本驱动程序的任何页面(如 17 或 13 或 11 )，它会显示 Trusted_Connection=yes
