I want to count the Child (ChildTable__c) objects for each ParentTable.

I try to run the following aggregate query:

Select Count (Id), THAKA__ParentTable__c, THAKA__ParentTable__r.Name from THAKA__ChildTable__c group by THAKA__ParentTable__c, THAKA__ParentTable__r.Name

And export it on CSV. The THAKA__ParentTable__r.Name is blank. This happens only when I have an Agregate query.

When I run the following query:

Select Id, THAKA__ParentTable__c, THAKA__ParentTable__r.Name from THAKA__ChildTable__c

The field THAKA__ParentTable__r.Name has the Name of the parent object.

I even tried using the C# application (API) and the aggregate query returns the parent object fields.

Anyone has seen this problem?
