访问SQL的iif语句太多

我有一个大的嵌套iif语句。我有16个不同的字段，我需要根据它们的初始值为它们赋值1或0。这是：

select
  iif(overlimitexception = "Yes",0,1) as OverLimit,
  iif(CashOutageIdentified = "Yes",0,1) AS CashOutage,
  iif(MissingAuditIdentified = "Yes",0,1) AS MissingAudit,
  iif(NightDropObserved = "Yes",0,1) AS NightDrop, 
  iif(SecurityTestComplete = "No",0,1) AS SecurityTest,
  iif(CashPatternIdentified = "Yes",0,1) AS CashPattern,
  iif(AllClearChange = "No",0,1) AS AllClear,
  iif(RobberyKitReview = "No",0,1),
  iif(EvacPlanReview = "No",0,1),
  iif(KeyComboIssue = "Yes",0,1) AS KeyCombo,
  iif(DualControlIssue = "Yes",0,1) AS DualControl,
  iif(TaIssue = "Yes", 0,1) AS TA,
  iif(CleanDeskIssue = "Yes",0,1) AS CleanDesk,
  iif(MonthlyOpsIssue = "Yes",0,1) AS MonthlyOps,
  iif(OverShortIssue = "Yes",0,1) AS OverShort,
  iif(CashTargetIssue = "Yes",0,1) AS CashTarget

如果我只处理一个领域，我可以很容易地解决这个问题，但我处理的是16个领域。有更好的方法吗？谢谢你的帮助

如果您对

iif

过敏，以下是一种可能的替代方法：

select
    1+(overlimitexception = "Yes") as OverLimit,
    1+(CashOutageIdentified = "Yes") AS CashOutage,
    1+(MissingAuditIdentified = "Yes") AS MissingAudit,
    1+(NightDropObserved = "Yes") AS NightDrop, 
    1+(SecurityTestComplete = "No") AS SecurityTest,
    1+(CashPatternIdentified = "Yes") AS CashPattern,
    1+(AllClearChange = "No") AS AllClear,
    1+(RobberyKitReview = "No"),
    1+(EvacPlanReview = "No"),
    1+(KeyComboIssue = "Yes") AS KeyCombo,
    1+(DualControlIssue = "Yes") AS DualControl,
    1+(TaIssue = "Yes") AS TA,
    1+(CleanDeskIssue = "Yes") AS CleanDesk,
    1+(MonthlyOpsIssue = "Yes") AS MonthlyOps,
    1+(OverShortIssue = "Yes") AS OverShort,
    1+(CashTargetIssue = "Yes") AS CashTarget

假设在所提到的字段中只有“否”和“是”值，您可以这样写

  1 - eval(overlimitexception) as OverLimit,
  -eval(SecurityTestComplete) AS SecurityTest,

还是快一点

  3 - len(overlimitexception) as OverLimit,
  -2 + len(SecurityTestComplete) AS SecurityTest,

不，我不这么认为。顺便说一句，那些

iif

s不是嵌套的。但你真的想将“是”标记为0吗？你是对的，它们不是。我知道，我们正在计算风险评估的总分，越低=越适合我们的目的。谢谢我想知道为什么您首先将是/否信息存储为文本字段？请更好地指定。每列只有一个操作，再简单不过了。
