错误在IF语句中使用多个子句SSRS

Question

我很难在SSRS中使用具有多个子句的if语句。

我使用的表达：

=IIF(DateDiff("d",Fields!Project_Target_Date.Value, Now())>-14 AND DateDiff("d",Fields!Project_Target_Date.Value, Now())<-1, "Yellow") OR IIF(DateDiff("d",Fields!Project_Target_Date.Value, Now())>-1, "Red", "Black") 

对于我得到的错误：

The Color expression for the textrun ‘Project_Target_Date.Paragraphs[0].TextRuns[0]’ contains an error: [BC30516] Overload resolution failed because no accessible 'IIf' accepts this number of arguments. 

我希望能设定目标日期的颜色以显示黄色，如果2周之内现在，如果目标日期已过去，则显示为红色，否则显示为黑色。

我想我离开/俯视简单的事情。

任何帮助，将不胜感激！

谢谢！

试试这个：

=IIF(
    DateDiff("d",Fields!Project_Target_Date.Value, Now())>-14 
    AND 
    DateDiff("d",Fields!Project_Target_Date.Value, Now())<-1, "Yellow", 
    IIF(
    DateDiff("d",Fields!Project_Target_Date.Value, Now())>-1, "Red","Black")) 

我比较喜欢的，而不是嵌套的综合投资框架使用开关：

=Switch(
    DateDiff("d",Fields!Project_Target_Date.Value, Now())>-14 AND 
    DateDiff("d",Fields!Project_Target_Date.Value, Now())<-1, 
    "Yellow", 
    DateDiff("d",Fields!Project_Target_Date.Value, Now())>-1, 
    "Red", 
    true,"Black" 
) 

让我知道，如果这有助于。

您错误地嵌套您的IIF。您可以使用类似：

=IIF(DateDiff("d",Fields!Project_Target_Date.Value, Now())>-14 AND DateDiff("d",Fields!Project_Target_Date.Value, Now())<-1, "Yellow",IIF(DateDiff("d",Fields!Project_Target_Date.Value, Now())>-1, "Red", "Black"))
