Python測試腳本：

# 配置數據庫連接

dsn = 'MySQLDataSource'

user = 'root'

password = 'YOUR_PASSWORD'

database = 'testdb'

# 創建連接字符串

conn_str = f'DSN={dsn};UID={user};PWD={password};DATABASE={database}'

# 嘗試連接到數據庫

try:

    conn = pyodbc.connect(conn_str)

    print("Connected to the database successfully!")

    conn.close()

except Exception as e:

    print(f"Failed to connect to the database: {e}")
