SQL-SSRS新手

如何向以下代码添加功能以将返回的NaN值更改为0或空白？我认为正在发生的情况是，同意和不同意的总和= 0我得到这个楠。我认为如果我不处理同意和不同意的类别，这对我来说会更容易。同样，SQL编程的新手。任何帮助将不胜感激。

Answer 1

尝试以下内容，

=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，请查看this

Answer 2

您应该在表达式中处理DIV 0问题，而不是将从除以0返回的文本替换为：

=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为零，则计算为 0/1 ，否则为 SUM（天）/ SUM（Fq），其中回复是同意或不同意。

而不是两个总和，只需在一个中使用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

此功能使您可以编写自定义代码来修复Nan的所有问题。这可以通过以下方式调用

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

您的代码如下

=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)))))

在SSRS表达式中删除嵌套iif中的NaN
