subquery - 使用两个不同的分隔符将 group_concat 转换为 group_concat

Question

我使用follown作为一部电影的页面

     SELECT 
    `mt_films`.`Title1` AS `Title1`,
    GROUP_CONCAT(DISTINCT `t_idiotita`.`idiotita`,
        ': ',
        `t_people`.`person`
        ORDER BY `t_idiotita`.`cnt_gr_id` ASC
        SEPARATOR ' ') AS `kati`
FROM
    ((`t_people`
    JOIN (`st_peoplefilms`
    JOIN `mt_films` ON ((`mt_films`.`ID_films` = `st_peoplefilms`.`ID_films`))) ON ((`t_people`.`ID_person` = `st_peoplefilms`.`ID_person`)))
    JOIN `t_idiotita` ON ((`st_peoplefilms`.`ID_idiotita` = `t_idiotita`.`ID_idiotita`)))
WHERE
    ((`st_peoplefilms`.`ID_idiotita` = 29)
        OR (`st_peoplefilms`.`ID_idiotita` = 33)
        OR (`st_peoplefilms`.`ID_idiotita` = 27)
        OR (`st_peoplefilms`.`ID_idiotita` = 12)
        OR (`st_peoplefilms`.`ID_idiotita` = 43)
        OR (`st_peoplefilms`.`ID_idiotita` = 11)
        OR (`st_peoplefilms`.`ID_idiotita` = 32)
        OR (`st_peoplefilms`.`ID_idiotita` = 5)
        OR (`st_peoplefilms`.`ID_idiotita` = 24)
        OR (`st_peoplefilms`.`ID_idiotita` = 14))
GROUP BY `mt_films`.`Title1`

那返回例如

Title1 | Dir.: John | Script: Peter | Script: Anna | ...
Title2 | Dir.: George | Dir.: Paul | Script: Gus | ...

但是，虽然对于许多电影来说，同一专业不止一个人，但我需要第二个 group_concat 来对同一专业的所有人进行分组。我还需要两种不同的分离。第一个“：”分隔专业，第二个“，”人

预期结果

Title1 | Dir.: John | Script: Peter, Anna | ...
Title2 | Dir.: George, Paul | Script: Gus | ...

有什么帮助吗？
