在上面的场景中，我需要找到销售时的价格

为此，我需要将其加入零售表

/* Retail Table */

ProductCode     ValidFrom         ValidTo          Retail 
----------     ------------     -------------    ----------              
   1264         2014-11-01       2014-11-04        11.99          
   1264         2014-11-05          NULL           22.99

从上面可以看出，以下日期之间的任何销售的零售额应为：

2014-11-01应该是11.99
2014-11-05到今天应该是22.99

因此，困难在于比较零售表和StoreSales表，检查零售是否匹配，如果不匹配，则计算损失

e、 g

销售额应为（11.99*12）+（22.99*9）=511.72

实际销售额为417.72美元

损失=94

试图获得的结果

ProductCode       Loss
-------------   ---------
   1264           94.00

如果我理解正确的话，任何帮助都将是非常好的

如果所有的销售都是以最高的价格进行的，您想知道区别。您可以将其计算为：

select ProductCode,
       ( max(s.Current_Retail) * sum(s.quantity) - sum(total_sales) ) as loss
from #StoreSales s
group by ProductCode;
