Sql加入地圖並用逗號分隔結果

Question

我有三張表。我已經使用查詢連接了它，但我想用逗號分隔結果而不是在不同的行上顯示結果。

1臺

ProgrammeId | Name 
==================== 
1 |Software Engineering           
2 | Game Design 

第二臺

CoordinatorId| CoordinatorName 
==================== 
1 |Bob           
2 | Ted 

3D表

ProgrammeId| CoordinatorId 
==================== 
1 | 1           
1 | 2 
2 | 1 

這是一個查詢。

SELECT a.ProgrammeId, a.Name, c.NameCoordinator 
FROM Programme a 
--Joining maptable for Programme and Coordinator 
INNER JOIN ProgrammeCoordinators b 
ON a.ProgrammeId = b.ProgrammeId 
INNER JOIN Coordinator c 
ON b.CoordinatorId = c.CoordinatorId 

輸出將是類似的東西：

ProgrammeId| Name | CoordinatorName 
================================== 
1 | Software Engineer | Bob           
1 | Software Engineer | Ted 
2 | Game Design | Ted 

我如何可以單獨顯示這一點：

1 | Software Engineer | Bob, Ted 

Answer 1

如果你的名字是長度爲100：

SELECT a.ProgrammeId, a.Name(Name,' ',100), c.NameCoordinator 
FROM Programme a 
--Joining maptable for Programme and Coordinator 
INNER JOIN ProgrammeCoordinators b 
ON a.ProgrammeId = b.ProgrammeId 
INNER JOIN Coordinator c 
ON b.CoordinatorId = c.CoordinatorId
