在SQL中将多行附加到单个列（分组串联）

Question

stu2024-06-20

我有一个存储过程，它返回这样的结果，对于一个记录，如果我有两个角色，我得到两个单独的行。我想只有这样一行：

UserId  FirstName   LastName    Role
    34      Rahul       Gupta       Manager
    34      Rahul       Gupta       Director

存储过程是：

UserId  FirstName   LastName    Role
34      Rahul       Gupta       Manager,Director

这不起作用..我在这里做错了

SELECT [USER].[USER_ID] AS [UserId]
      ,[FIRST_NM] AS FirstName
      ,[LST_NM] AS LastName
      ,[Role].[ROLE_ID] AS RoleId
      ,[Role].[ROLE_NM] AS Role
FROM [dbo].[USER] [User] (NOLOCK)
INNER JOIN dbo.USER_ROLE [USER_ROLE] on [User].USER_ID=[USER_ROLE].USER_ID
INNER JOIN dbo.ROLE [Role] on [Role].ROLE_ID=[USER_ROLE].ROLE_ID
WHERE [USER].[SSO_ID] = 'xyz'
