访问 IIF 语句以列出结果

Question

在 Access 2010 中，我试图列出我的 IIF 语句的结果，但由于某种原因无法正常工作。

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以下逻辑：如果字段为 Null，则 return Null，否则如果字段包含 "Failed" return "Failed"，否则 "Passed"，考虑：

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