ORACLE Select and group by excluding one field

Question

Dear community,
I have a very simple query (on Oracle 11g) to select 3 fields:
select field1, field2, field3, count(*) from table
where...
group by field1, field2, field3
having count(*) > 10;
Now, what I need, is exclude "field3" from the "group by" since I only need field 1 and 2 to be grouped, but I also need field3 in the output. As far I know, all the fields in the select must be reported also in "group by", so how can I handle that?
Thanks
Lucas

Welcome to the forum!
Whenever you post please provide your 4 digit Oracle version (result of SELECT * FROM V$VERSION). And when you post code use code tags, \ on the line before and after the code to preserve formatting. See the FAQ for other syntax and highlighting options.

Correct - for an aggregate query all columns in the select must be either aggragate functions or in the GROUP BY.

Well what is it you are counting? And how should the values of field3 relate to those groups?
Post some sample source data and the sample result data you want to produce.
