Question

我根据许多条件从数据库中取出记录，但现在我陷入了一个我想实现的条件，首先看代码。

ALTER PROCEDURE [dbo].[Report_SmsTwentyFourhours_sdpo_Sp]

    @ParentID int

AS
BEGIN

    Declare @MaxID bigint
    Set @MaxID = (Select Max(ID) from SdpoReplies_SmsComplaints where ParentSmsID= @ParentID)

    Declare @DateReceived DateTime
    Set @DateReceived= (Select Convert(varchar(17),SdpoReplies_SmsComplaints.ReceivingDateTime, 113) 
    from SdpoReplies_SmsComplaints 
    where ParentSmsID= @ParentID
    AND 
    SdpoReplies_SmsComplaints.ID = @MaxID)

    Declare @DateSent DateTime
    Set @DateSent = (Select SendMessages.SendingDateTime from SendMessages where BasicSmsID= @ParentID)

    Declare @TimeFrame int
    Set @TimeFrame = (Select DATEDIFF(hh, @DateSent, @DateReceived))

    Declare @Subject varchar(MAX)
    Set @Subject = (Select ReceivedMessages.Message from ReceivedMessages where ID= @ParentID)

    Declare @FromMobileNo varchar(20)
    Set @FromMobileNo = (Select ReceivedMessages.FromMobileNo from ReceivedMessages where ID= @ParentID)

    Declare @PoliceStation varchar(50)
    Set @PoliceStation = (Select CPOCMS.dbo.PoliceStations.PsName from CPOCMS.dbo.PoliceStations 
                           Inner Join CmsSMSDb.dbo.SendMessages
                           ON CmsSMSDb.dbo.SendMessages.Psi_ID = CPOCMS.dbo.PoliceStations.Psid 
                           where SendMessages.BasicSmsID= @ParentID)

    Declare @SdpoContact varchar(50)
    Set @SdpoContact = (Select CPOCMS.dbo.PoliceStations.sDpo_ContactNo from CPOCMS.dbo.PoliceStations
                        Inner Join CmsSMSDb.dbo.SendMessages
                        ON CmsSMSDb.dbo.SendMessages.Psi_ID = CPOCMS.dbo.PoliceStations.Psid 
                        where SendMessages.BasicSmsID= @ParentID)

    Declare @District varchar(20)
    Set @District= (Select CPOCMS.dbo.Districts.Name from CPOCMS.dbo.Districts
                    Inner Join CPOCMS.dbo.PoliceStations
                    ON CPOCMS.dbo.PoliceStations.District_ID =  CPOCMS.dbo.Districts.DistrictID
                    Inner Join CmsSMSDb.dbo.SendMessages
                    ON CmsSMSDb.dbo.SendMessages.Psi_ID= CPOCMS.dbo.PoliceStations.Psid
                    where CmsSMSDb.dbo.SendMessages.BasicSmsID= @ParentID)

    Select @ParentID as SmsID, @DateReceived as ReceivingDate, @Subject as ComplaintSubject,
     @FromMobileNo as IncommingNo, @PoliceStation as SDPOPoliceStation, @District as District , 
     @SdpoContact as SDPOContact, @TimeFrame as TimeFrame 
END

现在我想把它放在SdpoReplies_SmsComplaints.ReceivingDateTime的基础上，就像日期之间的日期一样怎么做得对？在这种情况下：

Select @ParentID as SmsID, @DateReceived as ReceivingDate, @Subject as ComplaintSubject,
         @FromMobileNo as IncommingNo, @PoliceStation as SDPOPoliceStation, @District as District , 
         @SdpoContact as SDPOContact, @TimeFrame as TimeFrame

Answer 1

如果我理解正确，您希望在WHERE子句中放置谓词，以根据日期范围限制结果。要做到这一点，你只需要添加一行：

SELECT *
FROM SdpoReplies_SmsComplaints
WHERE 
  -- Add the following line to your WHERE clause:
  ReceivingDateTime BETWEEN @Date1 AND @Date2

这将包括两个端点。请注意/如果@ Date1＆amp; @ Date2是与ReceivingDateTime不同的数据类型，如果您的某些数据从DATETIME隐式转换为DATE，则可以消除端点。

在日期的基础上从sql表中选择结果
