pyodbc- 与 SQL 服务器的连接失败

Question

我一直在尝试连接到 Microsoft SQL 服务器。我设置了 ODBC 连接并且测试成功。我没有使用 Windows 身份验证连接到 SQL 服务器，但它不断收到此错误：

Cannot be used with Windows authentication

InterfaceError: ('28000', '[28000] [Microsoft][ODBC SQL Server Driver][SQL Server]Login failed. The login is from an untrusted domain and cannot be used with Windows authentication. (18452) (SQLDriverConnect); [28000] [Microsoft][ODBC SQL Server Driver]Invalid connection string attribute (0); [28000] [Microsoft][ODBC SQL Server Driver][SQL Server]Login failed. The login is from an untrusted domain and cannot be used with Windows authentication. (18452); [28000] [Microsoft][ODBC SQL Server Driver]Invalid connection string attribute (0)')

这是我的代码：

import pyodbc
cnxn = pyodbc.connect(Driver='{SQL Server}',
                      Server='servername.abc.xyz.co.com',
                      username = 'user_xyz', 
                      password = 'abcdfgh')

我正在使用Windows7.请帮我调试这个问题

谢谢

Answer 1

我就是这样做的，而且效果很好：

import pyodbc 

server_name = "server_name"
db_name = "db_name"

server = "Server="+str(server_name)
db = "Database="+str(db_name)
key = "Driver={SQL Server Native Client 11.0};"+server+";"+db+";"+"Trusted_Connection=yes;"

cnxn = pyodbc.connect(key)

Answer 2

我能够通过如下定义 dsn 连接来解决这个问题：

dsn="DRIVER={SQL 
SERVER};server=ip_address_here;database=db_name_here;uid=user;pwd=password"

这有效，我能够连接并查询 sql 服务器。
