Answer 1

這個怎麼樣。你會看到的第一部分是CTE根據您的代碼（僅列別名改變/添加和刪除通過順序），這使得腳本的其餘部分是指它就像一個表：

With TeamResults as 
(
Select 
    date as MatchDate, Team, 
    (case when fthg > ftag then 'W' when fthg = ftag then 'D' when ftag > fthg then 'L' end) Mres 
     from 
     (
    select div, hometeam team, date, fthg, ftag from Matches 
union all 
    select div, awayteam team, date, ftag, fthg from Matches 
) a 
where Team like '%chelsea%' 
) 

SELECT t2.Team, TeamResultList = replace 
          ((SELECT Mres AS [data()] 
           FROM TeamResults t1 
           WHERE t1.Team = t2.Team 
           ORDER BY t1.MatchDate FOR xml path('')), ' ', ',') 
FROM TeamResults t2 
GROUP BY t2.Team
