Question

您好，我不确定这是否可以解决此问题，但如果您有解决方案或替代方法可以解决此问题，将不胜感激。

为了说明，我有一个跟踪号列表，我想将“ ShipDate”声明为“ AddedDate”，然后将“ DueDeliveryDate”声明为“ ShipDate” +天，具体取决于发货的日期。

这里的问题是，它将使用在“ ShipDate”和“ DueDeliveryDate”中都首先声明的相同日期更新所有跟踪号。

请参阅SQL代码：

import re
import dns.resolver
import socket
import smtplib
def email_verifier(email):

    match = re.match(r'([a-zA-Z0-9_\-\.]+)@([a-zA-Z0-9_\-\.]+)\.([a-zA-Z]{2,5})$', email)
    if(match == None):
        return "Invalid Email."
    else:
        splitEmail = email.split('@')
        domain = str(splitEmail[1])


        records = dns.resolver.query(domain, 'MX')
        mxRecord = records[0].exchange
        mxRecord = str(mxRecord)
        # Get local server hostname
        host = socket.gethostname()

        # SMTP lib setup (use debug level for full output)
        server = smtplib.SMTP()
        server.set_debuglevel(0)

        # SMTP Conversation
        server.connect(mxRecord)
        server.helo(host)
        server.mail('sender@gmail.com')
        code, message = server.rcpt(str(email))
        server.quit()

       #returns 250 if valid
        if code == 250:
            return ('Valid Email Address')
        else:
            return ('invalid Email Address')

email = input("Enter email address : ")
print(email_verifier(email))

这是表格的摘录：

Answer 1

Begin

Update CN
Set ShipDate = @ShipDate
,DueDeliveryDate = case 
   when datename(weekday,@ShipDate)  = 'Friday' 
         then dateadd(day,3,@ShipDate)
   when datename(weekday,@ShipDate)  = 'Saturday' 
        then dateadd(day,2,@ShipDate)
   else dateadd(day,1,@ShipDate) end
,UpdatedBy = 'IT ADMIN'
,UpdatedDate = getdate()
-- Select *    
FROM dbo.Consignment CN
Where cn.TrackingNumber in ( **List of tracking number** )

Answer 2

我会用case表达式重写它：

set @DueDeliveryDate = dateadd(day, (case datename(weekday,@ShipDate)
                                          when 'Friday' then 3
                                          when 'Saturday' then 2
                                          else 1 
                                     end), @ShipDate
                              )

update cm
     set ShipDate = @ShipDate,
         DueDeliveryDate = @DueDeliveryDate,
         UpdatedBy = 'IT ADMIN',
         UpdatedDate = getdate()  
from dbo.Consignment cn
where cn.TrackingNumber in ( **List of tracking number** );

请参阅下面的解决方案：

UPDATE a
SET ShipDate = a.AddedDate             
,DueDeliveryDate = CASE
                  WHEN datename(weekday,a.AddedDate)  = 'Friday' THEN 
                  dateadd(day,3,a.AddedDate)
                  WHEN datename(weekday,a.AddedDate)  = 'Saturday' THEN 
                   dateadd(day,3,a.AddedDate) 
                  ELSE dateadd(day,1,a.AddedDate) 
                  END
,UpdatedBy = 'IT ADMIN'
,UpdatedDate = getdate()
-- Select *    
FROM dbo.Consignment a
Where 
TrackingNumber in 
(
SELECT DISTINCT a.TrackingNumber 
FROM ConTransaction a
INNER JOIN Consignment b 
ON a.TrackingNumber = b.TrackingNumber
WHERE a.TrackingNumber in (SELECT TrackingNumber  
                                FROM Consignment  C WITH (NOLOCK) 
                                WHERE ShipDate > DateAdd(d, 7, 
Convert(smalldatetime,Convert(Varchar(10),getdate(),126)))
                                AND [Status] = 0
                                AND TrackingNumber IN
                                         ( 65560460605,
                                           50454646064 )
                            )
)

*所以我用“ AddedDate”更新了“ ShipDate”，然后根据我使用“ AddedDate”更新了“ DueDeliveryDate”的日期进行了修改

如果可以建议其他标题，则可以随时告诉我，这个问题会更好，我会进行更新。

感谢您的帮助！
