python使用pyodbc通过不同认证方式连接sqlserver数据源

1. 普通sqlserver认证连接

2. Azmure Microsoft Entra Password认证连接

3. 源码

# -*- coding: utf-8 -*-
import pyodbcprint(pyodbc.drivers())
# sqlserver authentation连接字符串
connection_string = ("DRIVER={ODBC Driver 17 for SQL Server};""SERVER=localhost;""DATABASE=testdb;""UID=your_username;""PWD=your_password;"
)# Microsoft Entra Password authentation连接字符串
connection_string = ("DRIVER={ODBC Driver 17 for SQL Server};""SERVER=localhost;""DATABASE=testdb;""UID=your_username;""PWD=your_password;"# "Authentication=ActiveDirectoryPassword;"  # 使用AD密码认证# "Authentication=ActiveDirectoryIntegrated;"  # 集成认证"Authentication=ActiveDirectoryInteractive;"  # 交互式认证，对于密码设置了过期时间的，运行后会弹框让输入密码，正确输入后可运行"Connection Timeout=30;"
)# 创建连接
conn = pyodbc.connect(connection_string)# 创建游标
cursor = conn.cursor()# 可以通过 cursor.execute() 执行 SQL 查询，并使用 fetch 方法获取结果：# 执行查询
cursor.execute("SELECT user_id, user_name FROM users")# 获取所有结果
rows = cursor.fetchall()# 遍历结果
for row in rows:print(f"User ID: {row.user_id}, User Name: {row.user_name}")
