Sql server 如何检查存储过程中的密码到期列是否只剩下14,7,3,2,1天？

我有一个sp，我检查用户的密码更改日期是否有14天 左（

flag=0）

，我向该用户发送电子邮件，并检查sp（通过 col.flag）如果电子邮件已发送或未发送。之后，我将更新 另一个SP（

ExpiryNotificationFlag

）中的标志列，指向其电子邮件已被 已经发送..现在我不知道如何检查7,3,2,1天作为标志 col值已为1

sp

你基本上是在抱怨：

“布尔数据类型只能存储两个值中的一个！”

事实上，所以将该标志替换为“剩余天数”列，并将其与14、7等进行比较

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

有时候，当列的名称更好时，这些问题就更容易考虑了。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      

  )  

为此，您必须将到期通知标志修改为int，而不是布尔值
之后，创建一个SP，u将从中更新值 0到1、1到2、2到3等

( (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      

  )
