这个怎么样？您将看到第一部分是基于您的代码的CTE（仅更改/添加了列别名并删除了顺序），这允许脚本的其余部分像表格一样引用它：

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

SQL获胜，绘制，丢失每个团队的表格
