Question

我的桌子如下。实际上球员按球队1和2的总积分排名。

teamNO  playername
===================
1        Joe
1        Jack
1        Micheal
1        Ken
1        Fendy
2        Helen
2        Mike  
2        Chris
2        George
2        Dan

我想写下我的桌子，但我只得到一排。我认为由于teamno只有1和2.有没有办法实现这一目标？提前致谢

Rank   Team1          Team2
================================
1       Joe           Helen
2       Jack          Mike
3       Micheal       Chris
4       Ken           George
5       Fendy         Dan

Answer 1

 ;WITH cte AS(
    SELECT * FROM (VALUES
    (1, 'Joe'),
    (1, 'Jack'),
    (1, 'Micheal'),
    (1, 'Ken'),
    (1, 'Fendy'),
    (2, 'Helen'),
    (2, 'Mike '),
    (2, 'Chris'),
    (2, 'George'),
    (2, 'Dan')
    ) as t(teamNO, playername)),
    final AS (
    SELECT ROW_NUMBER() OVER (PARTITION BY TeamNo ORDER BY TeamNo) AS [Rank],*
    FROM cte)

SELECT f1.[Rank], f1.playername as Team1, f2.playername as Team2
FROM final f1
LEFT JOIN final f2 ON f1.[Rank] = f2.[Rank] and f1.TeamNo != f2.TeamNo
WHERE f1.teamNO = 1

结果：

Rank                 Team1   Team2
-------------------- ------- -------
1                    Joe     Helen
2                    Jack    Mike 
3                    Micheal Chris
4                    Ken     George
5                    Fendy   Dan
