Question

您好我正在运行下面的查询，我的[sumofnetsales]金额为空值。有谁知道可能是什么问题？

另外，如果我想使用[SumofAmountShipped]列而不是在减法方程中再次求和，我该怎么做？谢谢。

Answer 1

您收到null，因为减法中的一个列值为null。就像：

1000 - null = null

您必须使用coalesce(<column>, 0)（= ANSI SQL方式）来避免这种情况，或使用ISNULL()函数（特定于SQL Server）。你的减法线看起来像：

sum(coalesce(ExtendedPrice, 0)) - coalesce(c.Amount,0) - coalesce(a.Amount, 0) 
    - coalesce(af.Amount, 0) - ... and so on ... [SumOfNetSales]

从第二点开始：你不能避免在减法中写出[SumofAmountShipped]列，因为你不能在同一个语句中使用刚刚定义的别名。

Answer 2

稍微难以理解您的代码，但问题很可能在于JOIN。

当使用左连接时，如果仅存在左侧，则它将返回右侧的左侧+ NULL。如果您执行任何涉及NULL的算术，结果将始终为NULL。

要解决此问题，请使用ISNULL函数为减法中的每个值返回0而不是NULL。

祝你好运！

Answer 3

您获得[sumofnetsales]的空值，因为您在表@InitialOrderDiscount（左连接@InitialOrderDiscount id on id.ShortItemNo = ss.ShortItemNo ）中没有匹配值。因此，为了避免使用NULL，您可以使用以下列：

ISNULL(id.Amount,0)[SumOfNetSales]

减去查询中的值
