如何将数据设为仅行而不是帐号的多行

Question

下面是我得到的结果，我应该得到的结果是排成一排。

  AccountNumber  Name   UnitNumber    AdmStatus    AdmitDate    Insurance1  Insurance2  Insurance3  Insurance4  Insurance5 
  V000123456       FERG     M000123456  DIS IN      11/11/2019      ins1                
  V000123456       FERG     M000123456  DIS IN      11/11/2019                ins2  

但是我需要将结果与保险2排在一起

       AccountNumber     Name   UnitNumber    AdmStatus    AdmitDate    Insurance1  Insurance2   Insurance3 Insurance4  Insurance5 
       V000123456      FERG     M000123456  DIS IN      11/11/2019      ins1         ins2   

这是我所附的查询

SELECT AccountNumber
    ,CASE 
        WHEN bio.InsuranceOrderID = '1'
            THEN bio.InsuranceID
        ELSE ''
        END AS 'Insurance1'
    ,CASE 
        WHEN bio.InsuranceOrderID = '2'
            THEN bio.InsuranceID
        ELSE ''
        END AS 'Insurance2'
    ,CASE 
        WHEN bio.InsuranceOrderID = '3'
            THEN bio.InsuranceID
        ELSE ''
        END AS 'Insurance3'
    ,CASE 
        WHEN bio.InsuranceOrderID = '4'
            THEN bio.InsuranceID
        ELSE ''
        END AS 'Insurance4'
    ,CASE 
        WHEN bio.InsuranceOrderID = '5'
            THEN bio.InsuranceID
        ELSE ''
        END AS 'Insurance5'
FROM BarVisits bv
LEFT OUTER JOIN BarInsuranceOrder bio ON bio.SourceID = bv.SourceID
    AND bv.VisitID = bio.VisitID
WHERE AccountNumber = 'V000123456'
GROUP BY AccountNumber
    ,bio.InsuranceOrderID
    ,bio.InsuranceID

Answer 1

对列使用聚合函数并修复GROUP BY：

 SELECT AccountNumber,
        MAX(case when bio.InsuranceOrderID ='1' then bio.InsuranceID ELSE '' END) AS Insurance1,
        MAX(case when bio.InsuranceOrderID ='2' then bio.InsuranceID ELSE '' END AS Insurance2,
        MAX(case when bio.InsuranceOrderID ='3' then bio.InsuranceID ELSE '' END AS Insurance3,
        MAX(case when bio.InsuranceOrderID ='4' then bio.InsuranceID ELSE '' END) AS Insurance4
        MAX(case when bio.InsuranceOrderID ='5' then bio.InsuranceID ELSE '' END) AS Insurance5
 FROM BarVisits bv LEFT JOIN
      BarInsuranceOrder bio
      ON bio.SourceID = bv.SourceID AND bv.VisitID = bio.VisitID
WHERE AccountNumber = 'V000123456'
GROUP BY AccountNumber
