这是我数据集的一部分。使用来自不同表的事务总和创建列实际。我需要在这里展示的是，如果Title是空的（不是NULL），那么Actual应该显示具有相同GroupBreakCon的所有内容的总和。

您还可以在最后一行看到总收入。 Actual应显示上面计算的两个小组总和的总和。

如果我们采用上面的例子，那么结果应该是这样的

ReportingCategory   Title   SubtotalGroup   GroupBreakCon   Actual
 Income Statement new BI    INCOME  1   0   NULL
 Income Statement new BI    Levy income NULL    0   -483541.57

 Income Statement new BI    TOTAL INCOME    3   200000000   -5037181

请有人建议如何实现这一目标。

您可以先尝试计算每个GroupbreakCon的总数，然后使用：

;with totals as
(
  select GroupBreakCon, sum(actual) as Subtotal
  from Income_Statement
  group by GroupBreakCon
)
select ReportingCategory, Title, case when len(Title) = 0 then Actual else (select subtotal from totals where GroupBreakCon = i.GroupBreakCon) end as calculated_actual
from Income_Statement
