Question

以下声明是我目前正在尝试确定自原始约会日期以来已过去天数的查询的一部分。

, DATEDIFF(D, a.AppointmentDate, GETDATE()) as DaysSinceApptDate

然而，我得到了消极和积极的结果。我需要更改查询以仅包含正面结果。所以，任何大于0的东西都是我想要的。

我的整个查询是：

    DECLARE @StartDate DATETIME = '2014-12-1'

    SELECT 
    ROW_NUMBER() OVER(ORDER BY ORDERS.ORDERDATE, PatientProfile.searchname) as   RowNumber
 , PatientProfile.searchname as PatientName
 , PatientProfile.Birthdate
 , ORDERS.ORDERDATE as OrderDate
 , DATEDIFF(D, ORDERS.ORDERDATE, ORDERS.DB_UPDATED_DATE) AS DaysToCurrentStatus
 , ORDERS.DESCRIPTION as ReferralType
 , CASE WHEN ORDERS.STATUS = 'U' Then 'Unsigned' 
    WHEN ORDERS.STATUS = 'H' Then 'Admin Hold'
    WHEN ORDERS.STATUS = 'S' Then 'InProcess'
    WHEN ORDERS.STATUS = 'C' Then 'Complete'
    WHEN ORDERS.STATUS = 'X' Then 'Cancelled'
    ELSE NULL END AS Status
 , df.ListName as OrderingProvider
 , ORDERS.DB_UPDATED_DATE as LastUpdated
 , ORDERS.CLINCOMMENTS as Comments
 , RIGHT(RTRIM(REPLACE(REPLACE(ORDERS.CLINCOMMENTS,CHAR(10),''),CHAR(13),'')), 18) as AppointmentDate /* Get rid of carriage returns, line breaks, and trailing spaces */
 , Coordinator = CASE
    WHEN ORDERS.ADMINCOMMENTS like 'Leticia%' then 'Leticia'
    WHEN ORDERS.ADMINCOMMENTS = 'Je%' then 'Jessica'
    WHEN ORDERS.ADMINCOMMENTS = 'Da%' then 'Dahlia'
    WHEN ORDERS.ADMINCOMMENTS = 'sandra' OR ORDERS.ADMINCOMMENTS = 'sc' THEN 'Sandra'
    ELSE NULL END
 , LOCREG.ABBREVNAME as Location
 INTO #TEMP
 FROM   (CentricityPS.dbo.PatientProfile PatientProfile 
 INNER JOIN CentricityPS.dbo.ORDERS ORDERS 
    ON PatientProfile.PId=ORDERS.PID) 
 INNER JOIN DoctorFacility df
    ON ORDERS.AUTHBYUSRID = DF.PVId
 INNER JOIN CentricityPS.dbo.LOCREG LOCREG 
    ON DF.LocationId=LOCREG.LOCID
 WHERE  ORDERS.ORDERDATE >= @StartDate
    AND ORDERS.ORDERTYPE='R' /*Referral*/

    AND ORDERS.XID= 1000000000000000000

    ORDER BY OrderingProvider

/* Cast only valid dates as AppointmentDates*/
SELECT RowNumber, CAST(AppointmentDate as DateTime) as AppointmentDate
INTO #Appts
FROM #TEMP
WHERE ISDATE(AppointmentDate) = 1

SELECT
    t.PatientName
    , t.Birthdate
    , t.OrderDate
    , t.ReferralType
    , t.Status
    , t.OrderingProvider
    , t.Comments
    , a.AppointmentDate as AppointmentDate
    , DATEDIFF(D, a.AppointmentDate, GETDATE()) as DaysSinceApptDate 
    , t.Coordinator
    , t.Location

FROM #TEMP t
    LEFT JOIN #Appts a
        ON a.RowNumber = t.RowNumber

DROP TABLE #TEMP，＃Apps 有没有办法在SQL查询中执行此操作？

看起来你的桌子有未来和过去的约会。使用WHERE a.AppointmentDate < GETDATE()仅获取过去的约会。这将消除负面结果。

在日期/时间查询中计算大于0的值
