在SSRS表达式中注意除以零误差

标签: runtime-error expression ssrs-2008-r2 divide-by-zero iif

我在报告中使用了以下表达式

            =IIF((Sum(Fields!Starts.Value)-Sum(Fields!Withdrawn.Value))=0, Nothing,
(Sum(Fields!Starts.Value)-Sum(Fields!Withdrawn.Value))/(Max(Fields!Year1Starts.Value)))

当我运行报告时,我收到消息并显示为#Error

    Warning 1   [rsRuntimeErrorInExpression] 
    The Value expression for the textrun ‘Textbox110.Paragraphs[0].TextRuns[0]’ contains an error: 
Attempted to divide by zero.

我尝试了这个但得到同样的错误:

    =IIF((Sum(Fields!Starts.Value) - Sum(Fields!Withdrawn.Value)) = 0, Nothing, 
(Sum(Fields!Starts.Value) - Sum(Fields!Withdrawn.Value))/ 
IIF(Max(Fields!Year1Starts.Value)=0,1,Max(Fields!Year1Starts‌​.Value)))

有人可以帮忙吗?

你必须处理除数并防止它作为值得到0。类似的东西:

=IIf(Fields!SomeField.Value = 0, 0, Fields!SomeOtherField.Value / IIf(Fields!SomeField.Value = 0, 1, Fields!SomeField.Value))

这将在除数中用1替换0,从而避免此错误。

我试过这个并且有效:

    =IIF(Max(Fields!Year1Starts.Value)=0,0,(Sum(Fields!Starts.Value) 
    - Sum(Fields!Withdrawn.Value))/IIF(Max(Fields!Year1Starts.Value)=0,1,
Max(Fields!Year1Starts.Value)))

我跟着这个:

=IIF ( Denominator = 0, Nothing, Numerator / IIF( Denominator = 0, 1, Denominator) )
