SQL足球积分表最后5场比赛

我有本赛季所有比赛的积分表的MSSQL查询。SQL足球积分表最后5场比赛

该数据库由一个表和一个表的列名组成;

Div (League name), Date, HomeTeam, AwayTeam, FTHG(FullTimeHomeGoal), FTAG (FullTimeAwayGoal)...

表结构

Div (nvarchar) Date (datetime) Hometeam (nvarchar) Awayteam (nvarchar) Fthg (float) Fthg (float)

我该怎么办的最后5场比赛/游戏积分榜？

select 
    team, 
    count(*) MP, 
    count(case when fthg > ftag then 1 end) W, 
    count(case when fthg = ftag then 1 end) D, 
    count(case when fthg < ftag then 1 end) L, 
    sum(fthg) GF, 
    sum(ftag) GA, 
    sum(fthg) - sum(ftag) GD, 
    sum(case when fthg > ftag then 3 else 0 end + case when fthg = ftag then 1 else 0 end) Pts 
    from (
    select Div, hometeam team, fthg, ftag, hthg, htag from Matches 
     union all 
    select Div, awayteam team, ftag, fthg, htag, hthg from Matches 
    ) a 
    where div='E0' 
group by team 
order by Pts desc

查询结果：

是不是有任何日期时间列？ – VDK

您是否尝试过Top 5 Date？ –

@ mehtat_90日期字段不适用于考试。我认为计算团队比赛号码更为正确 –

由于我的编辑杰里米真正的答案被拒绝后，我张贴我自己的，以信誉@JeremyReal（也upvoted）。

with table_a as (
    select Div, date, hometeam team, fthg, ftag, hthg, htag from Matches 
     union all 
    select Div, date, awayteam team, ftag, fthg, htag, hthg from Matches 
    ) 
,table_b as (
select * from (
    select a.* 
    ,row_number() over (partition by a.Div, a.team order by a.date desc) as row_num 
    from table_a a) x 
where row_num <= 5) 

select 
    Div, 
    team, 
    count(*) MP, 
    count(case when fthg > ftag then 1 end) W, 
    count(case when fthg = ftag then 1 end) D, 
    count(case when fthg < ftag then 1 end) L, 
    sum(fthg) GF, 
    sum(ftag) GA, 
    sum(fthg) - sum(ftag) GD, 
    sum(case when fthg > ftag then 3 else 0 end + case when fthg = ftag then 1 else 0 end) Pts 
    from table_b 
    where div='E0' --remove this line to show all divisions. 
group by Div, team 
order by Div, Pts desc

与杰里米的回答相比，这增加了一个别名（x）子查询的table_b CTE。它还将Div添加到该子查询中的分区以及主查询中的group by。

我认为在主要查询中包含Div的是可能是是在不同比赛中运行的同名球队。或者甚至原始数据可能包括“杯赛”和联赛的比赛，而且这两者不应该混为一谈。根据你的数据结构，你甚至可能在你的表中有多个季节的数据，这也需要处理。

我认为这是可行的。

with table_a as (
    select Div, date, hometeam team, fthg, ftag, hthg, htag from Matches 
     union all 
    select Div, date, awayteam team, ftag, fthg, htag, hthg from Matches 
    ) 
,table_b as (
select * from (
    select a.* 
    ,row_number() over (partition by a.team order by a.date desc) as row_num 
    from table_a a) 
where row_num <= 5) 

select 
    team, 
    count(*) MP, 
    count(case when fthg > ftag then 1 end) W, 
    count(case when fthg = ftag then 1 end) D, 
    count(case when fthg < ftag then 1 end) L, 
    sum(fthg) GF, 
    sum(ftag) GA, 
    sum(fthg) - sum(ftag) GD, 
    sum(case when fthg > ftag then 3 else 0 end + case when fthg = ftag then 1 else 0 end) Pts 
    from table_b 
    where div='E0' 
group by team 
order by Pts desc

谢谢，但只有match_id不存在表 –

@RobinVlaar好的，删除它。这不是必需的，但最初认为这是必需的。现在应该工作。 –

它不工作。没有任何结果..空 –
