数，通过与Max在PHP

Question

我

|name | number | 
|andi | 40  | 
|irfan | 30  | 
|lia | 60  | 
|andi | 50  | 
|lia | 10  | 
|sali | 60  | 

我想最大

显示这样的顺序组

name | number | 
andi | 90  | 
lia | 70  | 
sali | 60  | 
irfan | 30  | 

我的代码如下所示：

SELECT name, 
     COUNT(name) 
FROM tablename 
GROUP BY name 
ORDER BY MAX(number) 

而且它不工作。结果只是名称的工作组，而不是短期的最大数量

name | number | 
lia | 70  | 
sali | 60  | 
andi | 90  | 
irfan | 30  | 

Answer 1

你要做Select * from tablename Order By Number DESC

Answer 2

你想sum()不count()：

SELECT name, SUM(number) 
FROM tablename 
GROUP BY name 
ORDER BY SUM(number) DESC; 

Answer 3

SELECT name, 
     sum(number) as score 
FROM Test2 
GROUP BY name 
ORDER BY score DESC 

你要什么do是 - 总计“数字”列 - 将其设置为分数 - 按顺序排列得分降序

希望这有助于你
