用sql语句查询Show teamname and the total number of goals scored.
时间: 2024-01-04 21:02:27 浏览: 136
假设有两个表格,一个是“球队”表格(team),包含了球队的信息(team_id, team_name, team_country);另一个是“进球”表格(goal),包含了每个球员进球的记录(goal_id, match_id, team_id, player_id, goal_time)。
可以使用以下SQL语句查询每个球队的总进球数:
```
SELECT team.team_name, SUM(goal.goal_id) AS total_goals
FROM team
JOIN goal ON team.team_id = goal.team_id
GROUP BY team.team_name;
```
这个SQL语句使用了JOIN来将“球队”表格和“进球”表格关联,使用了SUM函数来计算每个球队的总进球数,使用了GROUP BY子句来按照球队分组,并且只显示球队名称和总进球数。

用sql语句查询For every match involving 'POL', show the matchid, date and the number of goals scored.
您好!针对您的问题,可以使用如下的SQL语句来查询:
```
SELECT matchid, date, COUNT(*) AS goals_scored
FROM match
WHERE (home_team = 'POL' OR away_team = 'POL')
GROUP BY matchid, date;
```
这条SQL语句会在 `match` 表中查询所有包括 'POL' 的比赛,然后统计每场比赛的进球数,并返回比赛ID、日期和进球数。其中,`COUNT(*)` 函数用于计算每场比赛的进球数,`GROUP BY` 子句用于将结果按比赛ID和日期分组。
希望能对您有所帮助!
用sql语句查询Show the stadium and the number of goals scored in each stadium.
可以使用如下的 SQL 查询语句:
```
SELECT Matches.stadium, COUNT(Goals.matchid) AS num_goals
FROM Matches
INNER JOIN Goals ON Matches.id = Goals.matchid
GROUP BY Matches.stadium;
```
这个查询语句将会返回每个球场的名称以及在该球场上进球的数量。它使用了一个内连接将 Matches 和 Goals 两个表连接在一起,然后使用 GROUP BY 子句按照球场名称进行分组,并使用 COUNT 函数统计每个球场上进球的数量。
