Column xxx is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause

Dear All,

I have a very simple query which executed no problems:

select * from Job

However if I just want to add 1 more stuff, it complains the error in the title:

select MAX(mas_no), * from Job

I know I could use query like:

select top 1 * from Job order by mas_no desc

to replace. But my question is: if I still want to use my query, how to do that? I don't want to list all columns in Job table like:

select MAX(mas_no), * from Job
group by Job.seq, job.type, job.xxx, job.yyy......

because there are too many colums.....

P.S. My final problem is i need to get a count(..) from another table, plus all Job table columns, like:

select count(r.Rec_Seq),Job.* from Job
Left JOIN [References] r on r.Rec_Seq = Job.Seq
GROUP BY
r.Rec_Seq,
(... do not want to list all job's columns...)

Thanks heaps!

Hi rrjegan17, you solution looks quite good. just one issue: the result gives me duplicated Job records when that job has multiple records in References table.

I found another solution like:

select match.cnt, j.* from Job j
left join
(
      select Rec_Seq,COUNT(*) as cnt
      from [References]
      group by Rec_Seq
) match
on match.Rec_Seq = j.Seq

If my Job table has 200 rows of records, and it gives me exact 200 rows of record, plus 1st column tells me how many matching records in References table.

Is it possible to further change your solution?

Thanks again!

Thomasian, your one is the same as my solution! Thanks mate!

>> just one issue: the result gives me duplicated Job records when that job has multiple records in References table.

Then try this..

select DISTINCT count(r.Rec_Seq) over ( partition by job.Seq) cnt ,Job.*
from Job
Left JOIN [References] r on r.Rec_Seq = Job.Seq

Hi rrjegan17,

Here is the error, which I think it's because there are 5 columns in Job table are "Text" type.

Msg 421, Level 16, State 1, Line 2
The text data type cannot be selected as DISTINCT because it is not comparable.
Msg 421, Level 16, State 1, Line 2

Msg 421, Level 16, State 1, Line 2
The text data type cannot be selected as DISTINCT because it is not comparable.

how could I do that? (assume not change from Text to varchar(max))

Thanks again!!

Hi rrjegan17,

Don't worry about that. I changed column type to Varchar(Max) and it works perfect!

Thanks again all!!
