访问IIF语句以列出结果

Question

在Access 2010中，我试图列出我的IIF语句中的结果，但由于某种原因无效。

DogTrainingStatus: IIf(([TrainingSuccess]>"*Pass*") And ([TrainingSuccess]>"*Failed*"),"Failed", IIf([TrainingSuccess]>"Failed","Failed"," "))

这是我的清单：

DogGroups - TrainingSuccess  
---------------------------  
A         - Pass, Pass, Pass  
B         - Pass, Pass, Failed  
C         - (Blank)  
D         - Failed, Failed, Failed  

我需要以下结果：

DogGroups - TrainingSuccess  
---------------------------  
A         - Pass  
B         - Failed  
C         - (Blank)  
D         - Failed  

Answer 1

假设字段包含CSV文本，并且您想要的结果遵循逻辑：如果field为Null，则返回Null，否则如果字段包含“Failed”则返回“Failed”，否则为“Passed”，请考虑：

DogTrainingStatus: IIf([TrainingSuccess] Is Null, Null, IIf([TrainingSuccess] LIKE "*Failed*", "Failed", "Passed"))
