We have a lookup relationship between a custom object Problem__c and cases, one problem can be related to many cases. I am trying to query the field or problem records and the number of related cases, this is working partially by doing this.
select problem__r.name,count(casenumber) from case where problem__c!=null group by problem__r.name limit 10
The problem is that I need to get more fields from the problem object so I tried this
select problem__r.name,problem__r.status__c,count(casenumber) from case where problem__c!=null group by problem__r.name limit 10
But I get the error Error: Field must be grouped or aggregated Status__c. How can I retrieve more fields from the parent object using this query?
