[转]rdlc报表中表达式的使用--switch和IIF范例

本文转自：http://hi.baidu.com/oypx1234/item/5b35dec4e03a3ad697445266

=Switch(

Fields!MLWHLO.Value = "C01",CountDistinct(Fields!MLCAMU.Value)*12

,Fields!MLWHLO.Value = "C02",CountDistinct(Fields!MLCAMU.Value)

,Fields!MLWHLO.Value = "C30",CountDistinct(Fields!MLCAMU.Value)

,Fields!MLWHLO.Value = "C03",CountDistinct(Fields!MLCAMU.Value)

,Fields!MLWHLO.Value = "C36",CountDistinct(Fields!MLCAMU.Value)

)

此部分没有对MLCAMU是否为空进行另外处理。

————————————————————————————————

Sum(

IIF(Trim(Fields!MLCAMU.Value)="",

Switch(

Fields!MLWHLO.Value = "C01",12

,Fields!MLWHLO.Value = "C02",1

,Fields!MLWHLO.Value = "C30",1

,Fields!MLWHLO.Value = "C03",1

,Fields!MLWHLO.Value = "C36",1

)

,0

)

)

排除MLCAMU为空的情况
