我正在尝试在我正在使用的多数据库项目上调用存储过程。我有两个存储过程正在工作，但这个特定的存储过程不起作用并返回错误：

这就是我调用存储过程的方式：
cursor = connections['backend'].cursor()
try:
cursor.callproc('[dbo].[GetLogonControlJSON]', ['10011', 'encrypted', '127.0.0.1'])
result_set = cursor.fetchall()
finally:
cursor.close()
我也是这样做的，但我仍然得到同样的错误：
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()
请帮帮我。 ：）
谢谢！
