  • Are you saying that you want to iterate over the children but have access to the related parent as well?

  • AS your requirement is to get related list record from parent query. , you can only get a list of children from the parent query and not individual records. So you have to use a For loop to iterate over each child. May be you can post what you tried and we can see if something is wrong. Why not consider querying children based on parentid if you are concerned about nested for loops?

Using Maps to get associated objects. In this case using the relationship from the child to get the parent.

Map<Id, SObject> parentObjMap = new Map<Id, SOBject>([SELECT Name, OtherValues__c FROM SObject WHERE SOME_CRITERIA]);

for (SObjectChild child: childObjects)
{
  Sobject parent = parentObjMap.get(child.ParentRelationship__c);

  //Do Work
}

This only has a single loop and gives you access to both the parent/child. Without more info you can't really get anything better than this.
