使用django-mssql调用存储过程

Question

我正在尝试调用我正在使用的多数据库项目上的存储过程。我有我的存储过程的2个工作，但这个特殊的存储过程不工作，并返回一个错误：

Traceback (most recent call last):

django.db.utils.Error: Attempting to fetch from a closed connection or empty record set 

这是我如何调用存储过程：

cursor = connections['backend'].cursor() 
    try: 
     cursor.callproc('[dbo].[GetLogonControlJSON]', ['10011', 'encrypted', '127.0.0.1']) 
     result_set = cursor.fetchall() 
    finally: 
     cursor.close() 

我这样做太，但我仍然得到相同的错误：

cursor = connections['backend'].cursor() 
try: 
    cursor.execute('EXEC [dbo].[GetLogonControlJSON] @LogonID=%s, @Password=%s, @IP=%s' % ('10011', 'encrypted', '127.0.0.1')) 
    result_set = cursor.fetchall() 
finally: 
    cursor.close() 

请帮助我。 :)

谢谢！

在这种情况下，您应该使用​​方法而不是callproc()。

错误消息告诉你的一切：

Attempting to fetch from a closed connection or empty record set
