try like this.

declare @table table (userid varchar(100))
insert @table values ('prs'),('ppp')
select  STUFF(( SELECT ','+CONVERT(VARCHAR,userid)
                FROM  @table 
                 FOR XML PATH('')), 1, 1, '') useridlist
-- prs,ppp

Mine looked almost identical ...

SELECT TOP (5) p.Name AS ProductName
, STUFF((SELECT TOP (5) ', ' + CAST(t.TransactionID AS VARCHAR(20)) 
FROM [AdventureWorks2014].[Production].[TransactionHistory] t 
WHERE T.ProductID = p.ProductID FOR XML PATH('')), 1, 1, '') as TransactionIds 
FROM [AdventureWorks2014].[Production].Product p

Such data is a bad idea, if you want to store userlists into a database, you'd have this design:

a) Users
ID, NAME

b) UserLists
ID, NAME

c) UsersInUserlists
ID, UserListID, UserID

To get a list of users:

SELECT Users.* FROM UserLists 
INNER JOIN UsersInUserLists On UsersInUserLists.UserListID = UserLists.ID
INNER JOIN Users ON Users.ID = UsersInUserLists.UserID
WHERE UserList.Name = 'list name' -- or if you know an ID value: WHERE UserList.ID = 3

This type of design is not just a theoretical idealized form of storing data. It is best practice. The UsersInUserlists can also be called an n:m relation, it's there to assign users to userlists or vice versa assign userlists to users.
