Microsoft SQL 查询 return 一行中的重复行

Question

我需要你的帮助来查询：

SELECT        
    'ABBOTT' AS Customername, 'DaleelMAMA' AS AccountName, 
    dbo.AccountBase.Name AS FullName, 
    dbo.AccountBase.Telephone1 AS  MobilePhone, 
    dbo.AccountBase.new_HomePhone1 AS HomePhone, 
    dbo.new_otherparentinformationBase.new_MobilePhone AS ParentPhone, 
    dbo.AccountBase.new_preferredlanguagetext AS Language
FROM            
    dbo.AccountBase 
LEFT OUTER JOIN
    dbo.new_otherparentinformationBase ON dbo.AccountBase.AccountId = 
        dbo.new_otherparentinformationBase.new_MotherName_lookup

这个查询 return 这个结果集：

原结果

ABBOTT  DaleelMAMA  Eman    55555555    NULL    56545412    Arabic
ABBOTT  DaleelMAMA  Eman    55555555    NULL    22222222    Arabic
ABBOTT  DaleelMAMA  Eman    55555555    NULL    25456552    Arabic
ABBOTT  DaleelMAMA  Hala    55552504    22252128    NULL    Arabic

但我需要将查询更新为 return 这个结果，但如下所示，如果你看到你会发现 Eman 行重复了三次，这是因为它包含不同的 parent phone 号码，所以我需要在一行中生成此结果，包括母亲号码及其相关 parent phones 号码。

请参阅上面link所需的结果，旨在寻找它，提前感谢您的支持。

如果它总是 4 ParentPhone 每个 Name 然后尝试这样的事情

;with cte as
(
SELECT        
    'ABBOTT' AS Customername, 
    'DaleelMAMA' AS AccountName, 
    ROW_NUMBER() over(partition by dbo.AccountBase.Name order by dbo.AccountBase.Telephone1) as rn,
    dbo.AccountBase.Name AS FullName, 
    dbo.AccountBase.Telephone1 AS  MobilePhone, 
    dbo.AccountBase.new_HomePhone1 AS HomePhone, 
    dbo.new_otherparentinformationBase.new_MobilePhone AS ParentPhone, 
    dbo.AccountBase.new_preferredlanguagetext AS Language
FROM            
    dbo.AccountBase 
LEFT OUTER JOIN
    dbo.new_otherparentinformationBase ON dbo.AccountBase.AccountId = dbo.new_otherparentinformationBase.new_MotherName_lookup
    )
SELECT Customername,
       AccountName,
       FullName,
       MobilePhone,
       Max(CASE WHEN rn = 1 THEN ParentPhone END) AS ParentPhone1,
       Max(CASE WHEN rn = 2 THEN ParentPhone END) AS ParentPhone2,
       Max(CASE WHEN rn = 3 THEN ParentPhone END) AS ParentPhone3,
       Max(CASE WHEN rn = 4 THEN ParentPhone END) AS ParentPhone4,
       Language
FROM   cte
GROUP  BY Customername,
          AccountName,
          FullName,
          MobilePhone,
          Language

注意： 如果每个 Name 的 ParentPhone 数量未知，那么您需要使用动态数据透视。也开始使用别名使查询更具可读性
