使用SQL中的stuff（）將多個值連接到單個列中（

Question

ID | NAME 
----|-------- 
1 |Ann 
2 |Jake 
1 |Julie 
3 |Paul 
2 |Shane 
4 |Kumi 

我想用下面的stuff()連接值。單個值不應受stuff()函數的影響。

ID | NAME 
----|-------- 
1 |Ann,Julie 
2 |Jake,Shane 
3 |Paul 
4 |Kumi 

如何做到這一點？

Answer 1

CREATE TABLE #A 
(ID INT, NAME VARCHAR(10)) 
INSERT INTO #A VALUES 
(1,'ANN'), 
(2,'JAKE'), 
(1,'JULIE'), 
(3,'PAUL'), 
(2,'SHANE'), 
(4,'KUMI') 

SELECT DISTINCT ID , 
STUFF((SELECT ','+NAME 
FROM #A T1 
WHERE T1.ID=T2.ID 
FOR XML PATH('')),1,1,'') FROM #A T2 

Answer 2

STUFF沒有做串聯，其對XML這確實this.Stuff只替換值按選擇

select id, 
stuff((select ','+name from #t1 t2 where t1.id=t2.id for xml path('')),1,1,'') 
from #t1 t1 
group by id
