我需要您的帮助，因为我不知道该怎么做：
我有三个MySQL表：
pcs_clubs ID，简称
pcs_candidates id，id_compet，id_club，id_season
pcs_matchs id，id_candidate_dom，id_candidate_ext，id_day，date_day，buts_dom，buts_ext，id_season，id_compet，验证
样本数据：
pcs_clubs
id shortname
1 Barcelona
2 Real Madrid
3 Sevilla
4 Deportivo
5 Espanyol
6 Real Zaragoza
pcs_candidates
id id_compet id_club id_season
1 1 1 1
2 1 2 1
3 1 3 1
4 1 4 1
5 1 5 1
6 1 6 1
pcs_matchs
+----+------------------+------------------+--------+------------+----------+----------+-----------+-----------+------------+

下一个MySQL查询成功生成所需比赛和赛季的联赛表：
SELECT
shortname AS Team, Sum(P) AS P,Sum(W) AS W,Sum(D) AS D,Sum(L) AS L,
SUM(F) as F,SUM(A) AS A,SUM(GD) AS GD,SUM(Pts) AS Pts
FROM(
SELECT
id_candidate_dom Team,
1 P,
IF(buts_dom > buts_ext,1,0) W,
IF(buts_dom = buts_ext,1,0) D,
IF(buts_dom < buts_ext,1,0) L,
buts_dom F,
buts_ext A,
buts_dom-buts_ext GD,
CASE WHEN buts_dom > buts_ext THEN 3 WHEN buts_dom = buts_ext THEN 1 ELSE 0 END PTS
FROM pcs_matchs
UNION ALL
SELECT
id_candidate_ext,
1,
IF(buts_dom < buts_ext,1,0),
IF(buts_dom = buts_ext,1,0),
IF(buts_dom > buts_ext,1,0),
buts_ext,
buts_dom,
buts_ext-buts_dom GD,
CASE WHEN buts_dom < buts_ext THEN 3 WHEN buts_dom = buts_ext THEN 1 ELSE 0 END
FROM pcs_matchs WHERE validation=1 AND id_compet=1 AND id_season=1
) as tot
JOIN pcs_candidates t ON tot.Team=t.id_club
JOIN pcs_clubs c ON c.id=t.id_club
GROUP BY Team
ORDER BY SUM(Pts) DESC, SUM(GD) DESC;
当前结果：
+------+---------------+---+---+---+---+---+----+-----+------------+
| | Team | P | W | D | L | F | A | GD | Pts |
+------+---------------+---+---+---+---+---+----+-----+------------+
| 1 | Sevilla | 3 | 3 | 0 | 0 | 6 | 2 | 4 | 9pts |
+------+---------------+---+---+---+---+---+----+-----+------------+

+------+---------------+---+---+---+---+---+----+-----+------------+
| 3 | Real Madrid | 3 | 1 | 1 | 1 | 6 | 6 | 0 | 4pts |
+------+---------------+---+---+---+---+---+----+-----+------------+
| 4 | Barcelona | 3 | 1 | 1 | 1 | 5 | 5 | 0 | 4pts |

+------+---------------+---+---+---+---+---+----+-----+------------+
| 6 | Espanyol | 3 | 0 | 1 | 2 | 4 | 8 | -4 | 1pts |
+------+---------------+---+---+---+---+---+----+-----+------------+
我想根据当前日期之前每支球队的前5场比赛，在联赛表中增加一列（当前表格）。我只需要简单地在每场比赛中添加一个角色，如果球队获胜，那么W，如果平局，然后D，如果输球，那么L。（如果一支球队还没有参加5场比赛，那么就不向该列添加角色）这个：
所需结果：
+---+---------------+---+---+---+---+---+---+----+------+-------------------------------------+
| | | | | | | | | | | Form (from newest result to oldest based on date of match) |
+---+---------------+---+---+---+---+---+---+----+------+-------------------------------------+
| 1 | Sevilla | 3 | 3 | 0 | 0 | 6 | 2 | 4 | 9pts | WWW |
+---+---------------+---+---+---+---+---+---+----+------+-------------------------------------+
| 2 | Real Zaragoza | 3 | 2 | 0 | 1 | 6 | 3 | 3 | 6pts | LWW |
+---+---------------+---+---+---+---+---+---+----+------+-------------------------------------+
| 3 | Real Madrid | 3 | 1 | 1 | 1 | 6 | 6 | 0 | 4pts | WLD |
+---+---------------+---+---+---+---+---+---+----+------+-------------------------------------+
| 4 | Barcelona | 3 | 1 | 1 | 1 | 5 | 5 | 0 | 4pts | WDL |
+---+---------------+---+---+---+---+---+---+----+------+-------------------------------------+

+---+---------------+---+---+---+---+---+---+----+------+-------------------------------------+
| 6 | Espanyol | 3 | 0 | 1 | 2 | 4 | 8 | -4 | 1pts | LLD |

答案 0 :(得分：0)
将date_match和match_result列添加到UNION中的查询后，请在第一个SELECT子句中添加以下列：
group_concat(match_result ORDER BY date_match DESC)
对于比赛结果：
CASE
WHEN buts_dom > buts_ext THEN 'W'
WHEN buts_dom = buts_ext THEN 'D'
WHEN buts_dom < buts_ext THEN 'L'
END match_result
