Question

我有一个查询，它给了我想要的结果。列名是这样的（我从查询中得到）：

RXID |DrName |SBOID |SBOName |RxHonoredDate |RxnHonoured |CallRecievedFrom |MobileNo

现在我有一个名为'SampleRepeat'的表。这有以下列

DrID |  CallRecievedFrom |  Mobile | SBOID  |RxnHonoured

（此处我们从表DrName和DrID到TblDr提取SBOName至SBOID）

这是我的疑问：

select G.RXID, NoOfRx, DrName,HospitalName,G.EmpCode AS SBOID ,TM_Name AS SBOName,CONVERT(DATETIME,H.CreatedDate) AS RxHonoredDate, DrSpeciality AS Speciality,
convert(DATETIME, G.CreatedDate) AS [RxGeneratedDate],COALESCE(H.rows, 0) AS RxnHonoured,
CallRecievedFrom,MobileNo ,G.HQ
from(
select RXID,SUM(RxGenerate) as NoOfRx, DrName,HospitalName,RX.EmpCode,TE.TM_Name,   DrSpeciality,convert(DATE,RX.CreatedDate)as CreatedDate,TE.Territory AS HQ
from tbl_rx RX
  left join tblEmployee TE on  TE.TM_Emp_Id=RX.EmpCode
GROUP BY RX.EmpCode,RX.DrName,RX.HospitalName,RX.CreatedDate,RX.DrSpeciality,TE.TM_Name,RX.RXID,TE.Territory 
)G
left join
( SELECT EmpCode,DrID,CreatedDate, SUM(MedToPCount) AS rows,CallRecievedFrom,MobileNo FROM tbl_MedicinToPatient WHERE Status = 'Delivered' GROUP BY EmpCode,DrID,CreatedDate,CallRecievedFrom,MobileNo
)H 
on H.DrID=G.RXID ORDER BY TM_Name, H.CreatedDate ASC

我想将此表值附加到查询结果的末尾，所有其他列将为null。我试过Union all但没有成功。我怎么做？任何帮助将不胜感激。

带有计算列的{p> UNION ALL或

SELECT
    *
FROM
(
    SELECT
        OrderID = 1 
        RXID, 
        DrName,
        SBOID,
        SBOName,
        RxHonoredDate,
        RxnHonoured,
        CallRecievedFrom,
        MobileNo  
    FROM 
        Query Q

    UNION

    SELECT 
        OrderID = 2
        RXID = NULL, 
        DrName = DrID, 
        SBOID = NULL, 
        SBOName = SBOID, 
        RxHonoredDate = NULL,  
        RxnHonoured, 
        CallRecievedFrom, 
        MobileNo = Mobile 
    FROM 
        SampleRequest) AS X
ORDER BY
    OrderID

应该有效。

确保SELECT中每列的订单和数据类型匹配。

SELECT
    RXID,
    DrName,
    SBOID,
    SBOName,
    RxHonoredDate,
    RxnHonoured,
    CallRecievedFrom,
    MobileNo
FROM
    YourFirstTable AS T
UNION ALL
SELECT
    RXID =  NULL,
    DrName =  NULL,
    SBOID =  T.SBOID,
    SBOName =  NULL,
    RxHonoredDate =  NULL,
    RxnHonoured =  T.RxnHonoured,
    CallRecievedFrom =  T.CallRecievedFrom,
    MobileNo =  T.Mobile
FROM
    YourSecondTable AS T

如何在SQL中将行追加到SELECT查询中？
