在MySQL中使用max（points）AS时如何获取完整行？

Question

I'm using this code.

$query = "SELECT max(Points) AS Points,City FROM Table_name WHERE Gender='Female' && Country='England' GROUP BY City";

I want it to give the complete row, not just Points and City. In my database the order is ID, City, Points, Name, Gender, Country. When I run this line of code it only gives me Points and City.

I have tried * but doesn't work.

I guess you want the whole row with the max points value, ie rows with Female/England/city where there are no one with higher points:

SELECT *
FROM Table_name t1
WHERE Gender='Female' 
 AND Country='England'
 AND NOT EXISTS (select 1 from Table_name t2
                 WHERE t2.Gender='Female' 
                   AND t2.Country='England'
                   AND t2.city = t1.city
                   AND t2.points > t1.points)

Will show both rows if it's a tie.

To return only one row / city, just add an < id condition in the EXISTS :

SELECT *
FROM Table_name t1
WHERE Gender='Female' 
 AND Country='England'
 AND NOT EXISTS (select 1 from Table_name t2
                 WHERE t2.Gender='Female' 
                   AND t2.Country='England'
                   AND t2.city = t1.city
                   AND t2.points > t1.points
                   AND t2.id < t1.id)
