表名： series_type
id| type| description
1 | 0| No series (Any team win 1 will be the winner)
2 | 1| Best of 3 (Any team wins 2 will be the winner else draw)
3 | 2| Best of 5 (Any team wins 3 will be the winner else draw)
表名： 匹配
ID| series_id | series_type | league_id | start_time |radiant_name | dire_name | radiant_win
1 | 8313 | 2 | 2096 | xxxxxxx1 | LV | LGD | true
2 | 8313 | 2 | 2096 | xxxxxxx2 | LGD | LV | false
3 | 8313 | 2 | 2096 | xxxxxxx3 | LV | LGD | false
4 | 8313 | 2 | 2096 | xxxxxxx4 | LV | LGD | false
5 | 8313 | 2 | 2096 | xxxxxxx5 | LGD | LV | false
输出 所需
使用league_id，start_time和radiant_name以及dire_name过滤
前
Team "LV" total series wins 3.
Team "LGD" total series wins 2.
Series winner is LV.
输出 我试过
按SERIES_ID和SUM使用Group但结果不同。
ex。 查询
SELECT SUM(IF(radiant_win = 1? 1, 0)) as LV, SUM(IF(radiant_win = 1? 0,1)) as LGD
ex。 不希望的结果~_~
Team "LV" wins 1.
Team "LGD" wins 4.

此查询为我提供了正确的结果，但是它提供了2列的问题。我需要一排
select *, count(winner) as count
from (select case radiant_win
when 1 then radiant_name
else dire_name
end as winner,
radiant_team_id,
dire_team_id,
series_id,
series_type
from matches
where leagueid = 2096 and
start_time >= 1415938900 and
((radiant_team_id= 1848158 and dire_team_id= 15)
or (radiant_team_id= 15 and dire_team_id= 1848158))
) as temp
group by winner;
查询结果 当前查询
matches查询结果 所需查询
winner| radiant_team_id| dire_team_id| series_id| series_type| count|
LGD| 1848158| 15| 8313| 2| 2
LV| 1848158| 15| 8313| 2| 3
答案 0 :(得分：4)
我将使用案例，计数和分组
select winner, count(winner) from
(select case radiant_win
when 1 then radiant_name
else dire_name
end as winner
FROM test.`match` ) as temp
group by winner;

我无法在您更新问题后找到start_time，radiant_team_id和dire_team_id作为您在评论中发布的内容。
以下答案可能不是您想要的答案，因为我在您更新后的问题上并不那么清楚。
select *, count(winner) as count
from (select case radiant_win
when 1 then radiant_name
else dire_name
end as winner,
radiant_team_id,
dire_team_id,
series_id,
series_type
from test.`matches`
where league_id = 2096 and
start_time >= 1415938900 and
((radiant_team_id= 1848158 and dire_team_id= 15)
or (radiant_team_id= 15 and dire_team_id= 1848158))
) as temp
group by winner;
