report developer 3.0日期函数

Question

=IIF (Fields!LastGiftDate.Value >0, (Format(Cdate (Fields!LastGiftDate.Value),"dd-MM-yyyy")), " ")

如果没有日期，上面的查询会给我空间，但如果有日期值，它会给我#Error。帮助

Answer 1

您需要使用isDate函数来确定它是否为日期。 SSRS iif条件未被短路。

=IIF (isDate(Fields!LastGiftDate.Value) 
     ,IIF (isDate(Fields!LastGiftDate.Value), (Format(Cdate (Fields!LastGiftDate.Value),"dd-MM-yyyy")),NOTHING)
     , " ")

OR

=IIF (isDate(Cdate(Fields!LastGiftDate.Value)) 
     ,IIF (isDate(Fields!LastGiftDate.Value), (Format(Cdate (Fields!LastGiftDate.Value),"dd-MM-yyyy")),NOTHING)
     , " ")

OR（尝试忽略短cicuit行为）

=IIF (isDate(Fields!LastGiftDate.Value), (Format(Cdate (Fields!LastGiftDate.Value),"dd-MM-yyyy")), " ")

OR

=IIF (isDate(Cdate(Fields!LastGiftDate.Value)), (Format(Cdate (Fields!LastGiftDate.Value),"dd-MM-yyyy")), " ")
