如何选择平均数据比SQL中的某些值更高？

Question

我有这个表：

如何选择这些部门那里的平均工资比greter的65000平均工资？

我尝试此查询，但它不工作：

SELECT * 
FROM 
    (SELECT 
     `instructer`.`dept_name`, 
     AVG(`instructer`.`salary`) AS Average 
    FROM 
     `instructer` 
    GROUP BY 
     `instructer`.`dept_name) 
WHERE 
    `Average` > 65000 

Solved Query:

SELECT 
     `instructer`.`dept_name`, AVG(`instructer`.`salary`) AS AVGSalary 
FROM 
     `instructer` 
GROUP BY 
     `instructer`.`dept_name` 
HAVING 
     (`AVGSalary`) > 65000 

Answer 1

尝试以下查询：

SELECT `instructer`.`dept_name`, AVG(`instructer`.`salary`) 
       AS Average 
       FROM `instructer` 
       GROUP BY `instructer`.`dept_name HAVING AVG(`instructer`.`salary`) > 65000
