 UPDATE dbo.wsm_Contact_PwdHistory  set ExpiryNotificationFlag = 1 WHERE ContactID = @ContactID

Answer 1

您基本上提出以下投诉：

“布尔数据类型只能存储两个值中的一个！”

确实，所以将该标志换成“剩余天数”列，并将其与14,7比较，无论如何....

注意，ExpiryNotificationFlag列不是一个好名字 - “PasswordExpiryEmailSent”怎么样

有时，当列具有更好的名称时，这些问题会更容易思考

你可以这样做

( (DATEDIFF(DAY,A.LastPDWChangeDate,getdate()) = 76 AND ISNULL(ExpiryNotificationFlag,0) = 0)  --14 days      

  or (DATEDIFF(DAY,A.LastPDWChangeDate,getdate()) = 83 AND ISNULL(ExpiryNotificationFlag,0) = 1) --7days      

  or (DATEDIFF(DAY,A.LastPDWChangeDate,getdate()) = 87 AND ISNULL(ExpiryNotificationFlag,0) = 2) --3 days      

  or (DATEDIFF(DAY,A.LastPDWChangeDate,getdate()) = 88 AND ISNULL(ExpiryNotificationFlag,0) = 3) --2 days      
  or (DATEDIFF(DAY,A.LastPDWChangeDate,getdate()) = 89 AND ISNULL(ExpiryNotificationFlag,0) = 4) --1 day      

  )

因为你必须将Expiry通知标志修改为int而不是布尔值在那之后创建一个SP，你将在哪里更新值 0到1,1到2,2到3等
