在我的基础上，我有这种关系（image）：
+------------+------------+-------------+------------------+------------+------------+
| fiche_jeux | | | fiche_jeux_infos | | |
+------------+------------+-------------+------------------+------------+------------+
| id | name | | jeux_id | date | category |

+------------+------------+-------------+------------------+------------+------------+
| 2 | Overwatch | | 2 | 2019-01-01 | overwatch |

+-------------+------+-------------+---------------------+--------------+
通过此查询，我获得了这样的concat“平台”：
SELECT GROUP_CONCAT(plateformes.name) as plateforme_name FROM plateformes
LEFT OUTER JOIN plateformes_details ON plateformes.id = plateformes_details.id_plateformes
RIGHT JOIN fiche_jeux ON fiche_jeux.id = plateformes_details.id_fiche_jeu
LEFT JOIN fiche_jeux_infos ON fiche_jeux_infos.jeux_id = fiche_jeux.id
GROUP BY fiche_jeux.name
效果很好，结果：
+-----------------+
| plateforme_name |
+-----------------+
| pc,ps4,xbox |
| pc |
| pc,xbox |
| pc,ps4,xbox |
| pc,ps4,xbox |
| |
| |
| .... |

现在，我如何才能以相同的结果组合模式和流派？

+--------+--------+------------+----------------+--------------+
我已经尝试过了，但是结果不好：
SELECT GROUP_CONCAT(plateformes.name) as plateforme_name, GROUP_CONCAT(modes.name) as modes_name, GROUP_CONCAT(genres.name) as genre_name FROM plateformes
INNER JOIN plateformes_details ON plateformes.id = plateformes_details.id_plateformes
LEFT OUTER JOIN fiche_jeux ON fiche_jeux.id = plateformes_details.id_fiche_jeu
LEFT OUTER JOIN fiche_jeux_infos ON fiche_jeux_infos.jeux_id = fiche_jeux.id
INNER JOIN modes_details ON modes_details.id_fiche_jeu = fiche_jeux.id
INNER JOIN modes ON modes.id = modes_details.id_modes
INNER JOIN genres_details ON genres_details.id_fiche_jeu = fiche_jeux.id
INNER JOIN genres ON genres.id = genres_details.id_genres
GROUP BY fiche_jeux.name
结果：
+---------------------------------------+--+-------------------------------------------------+--+-------------------------------------------------------+
| plateforme_name | | modes_name | | genre_name |
+---------------------------------------+--+-------------------------------------------------+--+-------------------------------------------------------+
| xbox,ps4,pc | | coopération,coopération,coopération | | aventure,aventure,aventure |
