我有两张表“activity_stats”＆amp; “activity_stats_values”
activity_stats table
# id, activity_id, kyf_id, kyf_sort
618 84 5 1
619 84 6 2
638 84 4 3
activity_stats_values table
# id, activity_id, player_id, kyf_id, value
2563 84 46 5 45
2564 84 46 6 60
2587 84 47 5 10
2588 84 47 6 25
2589 84 49 5 10
2590 84 49 6 40
2591 84 48 5 30
2592 84 48 6 15
2594 84 46 4 NULL
2595 84 47 4 80
2596 84 48 4 NULL
2597 84 49 4 NULL
要求
玩家应按降序排列值。意味着第一个关键字值最高的玩家（基于表“activity_stats”的字段“kyf_sort”的kyf_id，kyf_id位置）应该在顶部（然后是第二个关键值，然后是第三个关键值）。
预期输出
# id, activity_id, player_id, kyf_id, value kyf_sort
2563 84 46 5 45 1
2564 84 46 6 60 2
2594 84 46 4 NULL 3
2591 84 48 5 30 1
2592 84 48 6 15 2
2596 84 48 4 NULL 3
2589 84 49 5 10 1
2590 84 49 6 40 2
2597 84 49 4 NULL 3
2587 84 47 5 10 1
2588 84 47 6 25 2
2595 84 47 4 80 3
按顺序播放ID [46,48,49,47]
I tried the following query
SELECT ac_st_v.activity_id,ac_st_v.player_id,ac_st_v.value,ac_st.kyf_id,ac_st.kyf_sort,pl.first_name ,
(select max(value)
from activity_stats_values
where activity_id=ac_st_v.activity_id
and kyf_id=ac_st.kyf_id
group by activity_id) as m_value
FROM teamplayer.activity_stats_values as ac_st_v
JOIN teamplayer.activity_stats as ac_st
ON ac_st_v.activity_id=ac_st.activity_id
AND ac_st_v.kyf_id=ac_st.kyf_id
JOIN teamplayer.players as pl
ON ac_st_v.player_id=pl.id
where ac_st_v.activity_id= 84
order by ac_st_v.player_id,ac_st.kyf_sort,m_value
有没有办法对像这样的值进行排序？
