你試過了什麼？ – nrsharma

我試圖就這樣 –

與CTE爲（選擇a.id，c.name爲用戶1， b.name如基於role1 從一個的UserRole加入基於role1 B關於a.roleid = b.id加入第C USER1Ç .id = a.userid ） select user1，stuff（（從cte UL1選擇'，'+ role1，其中UL1.user1 = UL.user1 ORDER BY user1 FOR XML PATH（''）），1,2，' '）as [role1] from cte UL GROUP BY user1對不起答案Post box Not at show on my side所以... –

您可以通過創建存儲過程來完成。

CREATE PROC UserRoles 
(
    @UserId int 
) 

AS 
begin 
DECLARE @roles NVARCHAR(MAX) = '' 
SELECT @roles = @roles + ',' + t.Roles 
    FROM (SELECT r.NAME AS Roles FROM [User Role] ur 
    Inner JOIN [ROLE] r ON r.Id = ur.RoleId 
    INNER JOIN User1 u ON u.Id = ur.UserID WHERE u.Id = @UserId) t 
    SET @roles = RIGHT(@roles, LEN(@roles)-1) 
SELECT u.Id AS ID, u.NAME AS UserName, @roles AS Roles FROM USER1 u WHERE u.Id = @UserId 

end

我想爲將來的SQL標準提出一些函數CONCATROWS。

SELECT page_id,CONCATROWS('\n',partext) AS pagetext FROM paragraph ORDER BY parposition GROUP BY page_id

我不需要此功能，更比我燦count次......不，我需要很糟糕，但它會使生活變得更輕鬆。
