TSQL彙總不相互引用

Question

目前我正在試圖推出了一些數據，在以後的日子遠銷1分的記錄，其中lookupId所爲每個記錄是相同的

application_id card_holder_name transaction_id LookUpID 
1060693   Bob    6247460   765858xxxxxx9999_2017 
964851   James    6259094   765858xxxxxx9999_2017 
937321   Fred    6262332   765858xxxxxx9999_2017 

在這種情況下，應該成爲一條記錄，但應該彙總application_id，card_holder_name，transaction_id的數據。每個元素將被回車分隔開，但仍然相互關聯。

E.G.下面

LookUpID    Application_ID  Card_Holder_Name Transaction_ID 
765858xxxxxx9999_2017 1060693 964851 937321 Bob James Fred 6247460 6259094 6262332 

代碼觀看時的根據APPLICATION_ID但在card_holder_name當添加和tranaction_id他們都不是屬於彼此的那些工作正常。我認爲這不會像複製原來的代碼那麼簡單。任何人都可以請幫忙，代碼如下所示。

create table #test (application_id int, card_holder_name varchar(50), transaction_id int, LookUpID nvarchar(50)) 
insert into #test (application_id, card_holder_name, transaction_id, LookUpID) 
select 1060693,   'Bob',    6247460,  '765858xxxxxx9999_2017' 
union all 
select 964851,   'James',    6259094,   '765858xxxxxx9999_2017' 
union all 
select 937321,   'Fred',    6262332,   '765858xxxxxx9999_2017' 

select LookUpID, 
    stuff((SELECT distinct CHAR(13)+CHAR(10) + cast(application_id as varchar(10)) 
     FROM #test t2 
     where t2.LookUpID = t1.LookUpID 
     FOR XML PATH(''), TYPE).value('.','nvarchar(max)'),1,2,'') as Application_ID, 
stuff((SELECT distinct CHAR(13)+CHAR(10) + cast(transaction_id as varchar(10)) 
     FROM #test t2 
     where t2.LookUpID = t1.LookUpID 
     FOR XML PATH(''), TYPE).value('.','nvarchar(max)'),1,2,'') as Transaction_ID, 
    stuff((SELECT distinct CHAR(13)+CHAR(10) + cast(card_holder_name as varchar(10)) 
     FROM #test t2 
     where t2.LookUpID = t1.LookUpID 
     FOR XML PATH(''), TYPE).value('.','nvarchar(max)'),1,2,'') as Card_Holder_Name 
    from #test t1 where LookUpID = '765858xxxxxx9999_2017' 
group by LookUpID 

我得到的結果是

LookUpID    Application_ID  Transaction_ID Card_Holder_Name  
765858xxxxxx9999_2017 1060693 937231 964851 6247460 6259094 6262332 Bob Fred James 

感謝

信仰的飛躍的位在這裏，但如果你的意思是你想連接值的順序是相同的每個列，你將需要在每種情況下添加一個明確的ORDER BY子句。但是，您需要刪除DISTINCT才能這樣做，因爲您不能將GROUP BY一列和ORDER BY另一列（按列順序排列的值可能存在於多個組中，因此無法保持順序）。所以你的查詢將需要：

create table #test (application_id int, card_holder_name varchar(50), transaction_id int, LookUpID nvarchar(50)) 
insert into #test (application_id, card_holder_name, transaction_id, LookUpID) 
select 1060693,   'Bob',    6247460,  '765858xxxxxx9999_2017' 
union all 
select 964851,   'James',    6259094,   '765858xxxxxx9999_2017' 
union all 
select 937321,   'Fred',    6262332,   '765858xxxxxx9999_2017' 
union all 
select 937320,   'Pete',    600,   '765858xxxxxx9998_2017' 
union all 
select 937322,   'Darren',    601,   '765858xxxxxx9998_2017' 

select LookUpID, 
stuff((SELECT CHAR(13)+CHAR(10) + cast(application_id as varchar(10)) 
    FROM #test t2 
    where t2.LookUpID = t1.LookUpID 
    order by application_id 
    FOR XML PATH(''), TYPE).value('.','nvarchar(max)'),1,2,'') as Application_ID, 
stuff((SELECT CHAR(13)+CHAR(10) + cast(transaction_id as varchar(10)) 
    FROM #test t2 
    where t2.LookUpID = t1.LookUpID 
    order by application_id 
    FOR XML PATH(''), TYPE).value('.','nvarchar(max)'),1,2,'') as Transaction_ID, 
stuff((SELECT CHAR(13)+CHAR(10) + cast(card_holder_name as varchar(10)) 
    FROM #test t2 
    where t2.LookUpID = t1.LookUpID 
    order by application_id 
    FOR XML PATH(''), TYPE).value('.','nvarchar(max)'),1,2,'') as Card_Holder_Name 
from #test t1 
group by LookUpID
