Access / VBA 3075-Iif中的參數數量錯誤

Question

iif((([START DATE]<(cdate(format(year() & [WinterStartMonth] & [WinterStartDay],"####/##/##")))) AND ([START DATE]>(cdate(format(year() & [SummerStartMonth] & [SummerStartDay], "####/##/##"))))), (DateAdd("d", [WinterInspectionDropDead], [START DATE])), (DateAdd("d", [SummerInspectionDropDead], [START DATE]))) AS dropDead

有人可以發現問題嗎？ 我想我已經在OTT括起來了，但是我似乎無法擺脫這個錯誤。

通常，您可以使用VBA輕松發現錯誤，因此：

IIf([START DATE] < DateSerial(Year(Date),[WinterStartMonth],[WinterStartDay]) _
And [START DATE] > DateSerial(Year(Date),[SummerStartMonth],[SummerStartDay]), _
DateAdd("d", [WinterInspectionDropDead], [START DATE]), DateAdd("d", _
[SummerInspectionDropDead], [START DATE]))

只需刪除SQL的換行符即可：

IIf([START DATE] < DateSerial(Year(Date), [WinterStartMonth], [WinterStartDay]) 
  And [START DATE] > DateSerial(Year(Date),[SummerStartMonth], [SummerStartDay]),
  DateAdd("d", [WinterInspectionDropDead], [START DATE]),
  DateAdd("d", [SummerInspectionDropDead], [START DATE])) As Result

也許更好：

IIf([START DATE] < DateSerial(Year(Date), [WinterStartMonth], [WinterStartDay]) 
  And [START DATE] > DateSerial(Year(Date),[SummerStartMonth],[SummerStartDay]),
 [START DATE] + [WinterInspectionDropDead], 
 [START DATE] + [SummerInspectionDropDead]) 
As Result
