Question

最大平均我試圖得到最大的平均工資，我使用這樣的：

select max (avg_salary) 
from (select name, avg(salary) AS avg_salary 
    from employee 
    group by name); 

不過是另一種方式來獲得相同的結果，而無需使用子查詢？

Answer 1

SELECT AVG(salary) 
FROM employee 
GROUP BY name 
ORDER BY AVG(salary) DESC 
LIMIT 1 

Answer 2

使用這個代替

SELECT name, 
     avg(salary) AS avg_salary 
FROM employee 
GROUP BY name 
ORDER BY DESC avg_salary 
     LIMIT 1 

Answer 3

另外一個選擇是：

SELECT name, avg(salary) AS avg_salary 
FROM employee 
GROUP BY name 
ORDER BY 2 DESC LIMIT 1; 

Answer 4

試試這個...平均工資的這種遞減然後應用限制

SELECT AVG(salary),name 
FROM employee GROUP BY name 
ORDER BY AVG(salary) DESC 
LIMIT 1 

Answer 5

0一個員工的

SELECT name, 
     AVG(salary) AS avg_salary 
FROM employee

最大：

SELECT name, 
AVG(salary) AS avg_salary 
FROM employee 
GROUP BY name 
ORDER BY avg_salary DESC 
LIMIT 1
