调用存储过程python 2.7 Django 1.6.6 SQL Server

这是我们的settings.py

'default':  {
         'NAME': 'OUR_SERVER_NAME',
         'ENGINE': 'sqlserver_ado',
         'HOST': 'OUR_SERVER_IP',
         'USER': 'USER',
         'PASSWORD': 'OUR_SERVER_PASSWORD',
         'PORT': '1433',
         'OPTIONS' : {
            'provider': 'SQLOLEDB',
            'extra_params' : 'DataTypeCompatibility=80;MARS Connection=True'
        }
    }

我们使用的是Django 1.6.6和python 2.7，我们试图调用此存储过程（它返回一个临时表）：

但它返回一个错误：

你能帮我们吗

谢谢。

也许您正在尝试执行double fetchall（），因为我发现这是一种引发错误的方法。通过检查，我可以解决这个问题。我希望这对您有所帮助。也许您正在尝试执行double fetchall（），因为我发现这是一种引发错误的方法。通过检查，我可以解决这个问题。我希望这对你有帮助。
