多个条件求和'％_total'

Question

我的目标是生成生成独立总检查的代码。如下表所示：

 column1   Column2   Column3   value   independent total check
  A         B         c1         10      Null                   
  A         B         c2         11      Null                   
  A         B         C_total    21      21                    
  x         y         z1         10      Null                   
  x         y         z2         20      Null                   
  x         y         z_total    30      30                    

 I am trying to employ a conditional sum, but with no success! What I have at the moment is:

IF OBJECT_ID('tempdb..#Temp') IS NOT NULL DROP Table #Temp
select  t2.Column1, t2.Column2, t2.Column3,t2.value,
sum (case when (t2.column3 like '%_Total%' and t2.T_desk not like '%Total%') then t2.Value else Null end) over (partition by t2.Column2)  as "independent_total_check"into #Temp from #sometemptable

这似乎没有正常工作？！如何对成分进行求和并生成小计？非常感谢你提前！
