Question

select E.Job_ID, count(*), max(Employee_Salary) as kos, avg(Employee_Salary)
    from Employee E  
    inner join JOB D on E.Job_ID = D.Job_ID
    group by E.Job_ID

我想通过D.Functio订购我的结果，但我有这个错误

Msg 8120, Level 16, State 1, Line 1
Column 'JOB.Functio' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.

Answer 1

有关错误消息的不清楚之处？您正尝试通过未聚合的内容进行排序。这是一个解决方案：

order by max(d.Functio)

问题是别名“作业”未知。您需要使用分配给表格的“d”。

这应该有用，因为大概有一个job.Functio每个工作ID。另一个解决方法是将group by更改为：

group by e.Job_ID, d.Job.Functio

Answer 2

如果它是描述性列（作业函数？）

，您想将它添加到GROUP BY

select E.Job_ID, count(*), max(Employee_Salary) as kos, avg(Employee_Salary)
    from Employee E  
    inner join JOB D on E.Job_ID = D.Job_ID
    group by E.Job_ID, D.Functio
    order by D.Functio

否则在订购中你需要应用聚合函数，如min（），max（），avg（）等。

Answer 3

在D.Functio和Select

中加入Group by

select E.Job_ID, D.Functio,
     count(*), max(Employee_Salary) as kos, avg(Employee_Salary)
from Employee E  
inner join JOB D on E.Job_ID = D.Job_ID
group by E.Job_ID, D.Functio
order by D.Functio
