特定于SQL的DATEADD要求

我有三个DM_事件。事件代码：

在本例中，我需要使用一个日期参数来选择最新的所需报告日期：“4/28/15”以提取截至该日期的每个项目的SUMDM_DAILYCOST.cost_。”使用所选日期，CMP'和WOV'可以正常工作

但是，对于代码“DRL”，我需要提取DATEADDd的每个项目的SUMDM_DAILYCOST.cost_，-1、'4/28/15'

我想我让事情变得更难了，但我一直在寻找解决办法。非常感谢您的任何见解

您所需要的只是WHERE语句中的正确条件。您应仅选择日期为'4/28/15'的'CMP'和'WOV'事件以及日期为'4/28/15'的'DRL'事件ADDD，-1、'4/28/15'：

并从查询中删除HAVING语句。

Heh，看起来像EDM；
