I have a lookup field on case which points to case object. (Field: Parent\_\_c). I want to query child case records from a parent case using an aggregate query. Below is the query I have used-

```
[SELECT Id, (SELECT Id,parent__c FROM Cases) FROM Case WHERE Id IN:SetIds ] 

```

However, this query is not returning anything in 'Cases' in spite of 'Child Relationship Name' for the field being 'Cases'.
I know I am definitely missing something here. Hence request someone to please help me towards implementing my requirement.
