Question

我在这里列出了一个存储过程问题::

例如，客户A具有： i。）前30天五个订单， ii。）前60天的五个订单， iii。）前90天的五个订单

所以结果应该是：

     A.) First 30 Days: Five orders
     B.) First 60 Days: Five + Five = 10 Orders
     C.) First 90 Days: Five + Five + Five = 15 Orders

但是，我的存储过程显示所有30,60和90天的'15订单'。你能不能请我帮忙，以便我的存储程序在30天内显示'5个订单'，在60天内显示'10个订单'，在90天内显示'15个订单'。 [以下是该代码的一部分] 谢谢您的帮助。

Answer 1

我可能在这里遗漏了一些东西，但你对临时表的3个查询似乎都是同一个查询。您没有在WHERE子句中按日期过滤，因此它们都会得到相同的结果（15个订单）。

存储过程：即使订单日期不同，三列中的值也相同
