如果我按字段添加组，则2个字段的总和显示不同的值

分类：编程问答

如何解决如果我按字段添加组，则2个字段的总和显示不同的值

这是在Sql Server 2019中

我有一个大型查询，该查询由1个包含产品的基本表（variantID是主键）和8个子查询组成，这些子查询汇总了不同时间段内的销售额并将返回的数据返回到VariantID级别（再次，variantID成为主键）。所有子查询都通过左外部联接连接到产品表。

在2个字段上求和时，我得到奇怪的结果： 当SUM（V_LW_SKU_SLS.UnitsSold）-sum（V_LW_RETURNS.quantity）为空时的情况则为0 ELSE SUM（V_LW_SKU_SLS.UnitsSold）-sum（V_LW_RETURNS.quantity）END AS LW_NET_DEMAND_QTY

如果我分别汇总销售的单位和返回的数量作为单独的列，则这些值是正确的。如果没有按节分组（并且select语句中没有其他字段），则以上语句是正确的，但是如果我按字段添加分组，则该值将完全错误。

由于即使在有group by语句的情况下，作为单独列的值也是正确的，所以我没有认真研究所有子查询。

仅添加group by可能导致上述表达式中的结果不同？ 以下是完整（且非常大）的查询：

解决方法

对于LW_NET_DEMAND_AMT列和LW_NET_DEMAND_QTY列，我在每个SUM（）函数内添加了ISNULL（）函数。这样会产生预期的结果吗？
