SQL 数据透视表 table 中的列仍然获得 NULL 值
Still getting NULL value for column in SQL pivot table
有点难倒这个。在我下面的查询中，它输出正常，除了一个月，其中一个项目组没有该月的发票。因此，它输出一个空白字段，这反过来又没有给我该行的总计。

如果我将 select 语句中的值更改为 ISNULL([9],0)，那么当月它会为我输出 0.00，但在总计列中仍会给出空白值对于该行，即使每隔一个月都有值。
一旦某个月没有任何发票，它就会拒绝将其余月份相加。理想情况下，如果该月没有发票，我只会得到 0 值，但总计仍然存在。以今年为例，如果一个项目组在 1 月有 15000 个，在 2 月有 4000 个，那么我的总计为 19000，因为我们还没有达到任何其他月份。
编辑：添加了图像以显示当前结果，如您所见，工业的 Sep 是空白的，该行的总计 (GT) 也是空白。这应该是那个月的 0 值，并且仍然有所有月份的总和。
value + NULL 将始终 return NULL。所以你需要 ISNULL 这里：
ISNULL([1],0) + ISNULL[2],0) + ISNULL[3],0) + ISNULL[4],0) + ISNULL[5],0) + ISNULL[6],0) + ISNULL[7],0) + ISNULL[8],0) + ISNULL[9],0) + ISNULL[10],0) + ISNULL[11],0) + ISNULL[12] AS [Grand Total]
如果您通过条件聚合使用自定义数据透视表，例如：
Jan = SUM(CASE WHEN Month = 1 THEN T END),
Feb = SUM(CASE WHEN Month = 2 THEN T END),
那么你可以做得更简单：SUM(T) AS [Grand Total]
