不等於表達

Question

我期待在使用4個表達式3爲等於和1爲不平等，但不計算不等於使用

IM。

=sum(iif(Fields!NEW_SUPPLIER.Value = "Eon", 1,0) 
And (Fields!WeekDay.Value = "Monday") 
And (Fields!UTILITY.Value = "Elec") 
And (Fields!OLD_SUPPLIER.Value <> "Eon")) 

請有人指出我在正確的方向。

Answer 1

你需要確保所有的檢查都在IIf表達的第一個參數：

=sum 
(
    iif 
    (
     Fields!NEW_SUPPLIER.Value = "Eon" 
      And Fields!WeekDay.Value = "Monday" 
      And Fields!UTILITY.Value = "Elec" 
      And Fields!OLD_SUPPLIER.Value <> "Eon" 
     ,1 
     ,0 
    ) 
)
