Question

我有一个大的SSRS报告，我试图从多个字段中获取最大值。现在我让IIF在两个日期之间获取MAX值，但我想要报告中所有字段的MAX值。这是我必须在2个值之间获取MAX

=IIF(((IIF(Fields!OnOrder1Day.Value<Fields!Sold1Day.Value, 
Fields!Sold1Day.Value, Fields!OnOrder1Day.Value) + 
IIF(Fields!OnOrder2Day.Value<Fields!Sold2Day.Value, Fields!Sold2Day.Value, 
Fields!OnOrder2Day.Value) + 
IIF(Fields!OnOrder3Day.Value<Fields!Sold3Day.Value, Fields!Sold3Day.Value, 
Fields!OnOrder3Day.Value)) - (Fields!lonhand.Value - 
Fields!OnOrderToday.Value)-Fields!onpo.Value)<0, 0, 
((IIF(Fields!OnOrder1Day.Value<Fields!Sold1Day.Value, Fields!Sold1Day.Value, 
Fields!OnOrder1Day.Value) + 
IIF(Fields!OnOrder2Day.Value<Fields!Sold2Day.Value, Fields!Sold2Day.Value, 
Fields!OnOrder2Day.Value) + 
IIF(Fields!OnOrder3Day.Value<Fields!Sold3Day.Value, Fields!Sold3Day.Value, 
Fields!OnOrder3Day.Value)) - (Fields!lonhand.Value - 
Fields!OnOrderToday.Value)-Fields!onpo.Value))

我想要做的是从以下所有字段中找到MAX：

Fields!OnOrder1Day.Value
Fields!Sold1Day.Value
Fields!OnOrder2Day.Value
Fields!Sold2Day.Value
Fields!OnOrder3Day.Value
Fields!Sold3Day.Value
Fields!OnOrder4Day.Value
Fields!Sold4Day.Value
Fields!OnOrder5Day.Value
Fields!Sold5Day.Value
Fields!OnOrder6Day.Value
Fields!Sold6Day.Value

是否可以执行类似

的操作

MAX(Fields!OnOrder1Day.Value,Fields!Sold1Day.Value,Fields!OnOrder2Day.Value,Fields!Sold2Day.Value,Fields!OnOrder3Day.Value,Fields!Sold3Day.Value,Fields!OnOrder4Day.Value,Fields!Sold4Day.Value,Fields!OnOrder5Day.Value,Fields!Sold5Day.Value,Fields!OnOrder6Day.Value,Fields!Sold6Day.Value)

Answer 1

如果我理解正确，您需要数据集中多个字段的最高值。基本上，你想要最大的最大值。它可以使用嵌入式IIF的负载和负载，只是包子中的疼痛。

IIF(
    (MAX(Fields!OnOrder1Day.Value) > MAX(Fields!OnOrder2Day.Value)) AND
    (MAX(Fields!OnOrder1Day.Value) > MAX(Fields!OnOrder3Day.Value)) *ETC*,
    Fields!OnOrder1Day.Value,
    IIF(
         (MAX(Fields!OnOrder2Day.Value) > MAX(Fields!OnOrder1Day.Value)) AND
         (MAX(Fields!OnOrder2Day.Value) > MAX(Fields!OnOrder3Day.Value)) *ETC*,
         MAX(Fields!OnOrder2Day.Value,
         IIF( *ETC*),
    ),
)

您可以添加自定义功能，诸如此类

Public Function GetMaxDate(val1 as Date, val2 as Date) as Date

    Return iif(val1 > val2, val1, val2)

End Function

并在您的表达式中使用它

=Code.GetMaxDate(Code.GetMaxDate(Code.GetMaxDate(Code.GetMaxDate(Max(Fields!OnOrder1Day.Value),
                                                                 Max(Fields!Sold1Day.Value)
                                                                ),
                                                 Max(Fields!OnOrder2Day.Value)
                                                ),
                                 Max(Fields!OnOrder2Day.Value)
                                ),
                 Max(Fields!OnOrder3Day.Value)
                )

等

或根据需要定义其他任何函数参数

从SSRS中的多个字段中选择MAX
