如何 select 具有其他列最大值的列,以及另一个 table 中列的所有对应行?

How to select a column with max value of other column, and all corresponding rows of column in another table?

两个给定的表:

问题:Select成本最高的activity以及其中注册的学生姓名。

结果应为:activity 列(高尔夫)和学生列(马克·安东尼)。 在这种情况下,只有一个学生注册,但如果有更多学生注册,我想考虑一个案例。

我尝试了各种解决方案,但似乎无法解决问题。

感谢任何提示,谢谢。

编辑:我看到我被否决了,我不想展示我的尝试,因为我认为它偏离了目标,但这里有一些:

SELECT s.Student, a.Activity from Activities as a inner join Students as s 
ON a.ID = s.ID where a.Cost = (select max(a.Cost))

SELECT s.Student, a.cost, a.Activity from Activities as a inner join Students `as s ON a.ID = s.ID`
group by s.Student having a.cost = max(a.cost)

以下查询有效。

但请下次don't use images and you should also take a look at normalisation

CREATE TABLE activity (
  `ID` INTEGER,
  `Activity` VARCHAR(8),
  `Cost` INTEGER
);

INSERT INTO activity
  (`ID`, `Activity`, `Cost`)
VALUES
  ('84', 'Swimming', '17'),
  ('84', 'Tennis', '36'),
  ('100', 'Squash', '40'),
  ('100', 'Swimming', '17'),
  ('182', 'Tennis', '36'),
  ('219', 'Golf', '47'),
  ('219', 'Swimming', '15'),
  ('219', 'Squash', '40');
CREATE TABLE students (
  `Student` VARCHAR(11),
  `ID` INTEGER
);

INSERT INTO students
  (`Student`, `ID`)
VALUES
  ('John Smith', '84'),
  ('Jane Bloggs', '100'),
  ('John Smith', '182'),
  ('Mark Antor', '219');
SELECT Student,Activity
FROM  students s INNER JOIN (
SELECT id,Activity FROm activity WHERE Cost = (SELECT MAX(Cost) FROM activity)) a ON s.ID = a.id
Student    | Activity
:--------- | :-------
Mark Antor | Golf
