在SSRS表達式中的嵌套iif中刪除NaN

Question

SQL-SSRS的新功能

如何在以下代碼中添加功能，以將返回的NaN值更改為0或空白？ 我認為正在發生的情況是“同意”與“不同意”之和= 0我得到了這個Nan。 我認為，如果我不處理“同意”和“不同意”類別，這對我來說會更容易。 同樣，這是SQL編程的新功能。 任何幫助將不勝感激。

=(Sum(iif(Fields!Response.Value = "Agreed",Fields!Days.Value,0)) + Sum(iif(Fields!Response.Value = "Disagreed",Fields!Days.Value,0)))/(Sum(iif(Fields!Response.Value = "Agreed",Fields!Fq.Value,0)) + Sum(iif(Fields!Response.Value = "Disagreed",Fields!Fq.Value,0)))

Answer 1

嘗試以下類似的方法，

=Replace((Sum(IIF(Fields!Response.Value = "Agreed",Fields!Days.Value,0)) + 
Sum(IIF(Fields!Response.Value = "Disagreed",Fields!Days.Value,0))),"NaN","0")
/ Replace((Sum(IIF(Fields!Response.Value = "Agreed",Fields!Fq.Value,0)) 
+ Sum(IIF(Fields!Response.Value = "Disagreed",Fields!Fq.Value,0))),"NaN","0")

另外，看看這個

Answer 2

您應該處理表達式中的DIV 0問題，而不是替換從零除返回的文本：

=IIF(
    SUM(IIF(Fields!Response.Value = "Agreed" OR Fields!Response.Value = "Disagreed", Fields!Fq.Value, 0)) = 0, 0, 
        SUM(IIF(Fields!Response.Value = "Agreed" OR Fields!Response.Value = "Disagreed", Fields!Days.Value, 0)))
/IIF(
    SUM(IIF(Fields!Response.Value = "Agreed" OR Fields!Response.Value = "Disagreed", Fields!Fq.Value, 0)) = 0, 1, 
        SUM(IIF(Fields!Response.Value = "Agreed" OR Fields!Response.Value = "Disagreed", Fields!Fq.Value, 0)))

如果SUM 為零 ，則計算為0/1，否則為“ 同意”或“ 不同意”的SUM（天）/ SUM（Fq） 。

而不是兩個和，只需在一個中使用OR。

Answer 3

Public Function Divider (ByVal Dividend As Double, ByVal Divisor As Double)
If IsNothing(Divisor) Or Divisor = 0
  Return 0
Else
  Return Dividend/Divisor
End If
End Function 

此功能使您可以編寫自定義代碼來解決Nan的所有問題。 這可以由下面稱為

=Code.Divider(Fields!FieldA.Value, Fields!FieldB.Value)

您的代碼如下

=Code.Divider(((Sum(iif(Fields!Response.Value = "Agreed",Fields!Days.Value,0)) + Sum(iif(Fields!Response.Value = "Disagreed",Fields!Days.Value,0))), ((Sum(iif(Fields!Response.Value = "Agreed",Fields!Fq.Value,0)) + Sum(iif(Fields!Response.Value = "Disagreed",Fields!Fq.Value,0)))))
