SOQL Relationship Quieries: how to fetch

Hello All,

I am joining objects to get the Approval comments, actor for the specific target object id. However, i need to know how to fetch the data from the result list of data.Please help! 
processinstance = [SELECT Id,TargetObjectid, Status,(select id,actor.name from Workitems),(SELECT Id,StepStatus, Comments,Actor.Name,ActorId FROM Steps) FROM ProcessInstance where TargetObjectId=:setOfQuoteId];
	
	for(ProcessInstance pi:processinstance){
      ActorId.add(pi.ProcessInstanceStep.ActorId); // Error is here
		//ActorId.add(pi.ActorId);
	}

Thanks,
Raja

Hi Raja,

You need to find the relation name
GoTo Steps object and search for MasterDetail(Lookup) and locate the ProcessInstance object and see what is the relationship name 
Say the name is ProcessInstanceStep__c.
In your code you are required to use ProcessInstanceStep__r

And the code should look like 
  
processinstance = [SELECT Id,TargetObjectid, Status,(select id,actor.name from Workitems),(SELECT Id,StepStatus, Comments,Actor.Name,ActorId FROM Steps) FROM ProcessInstance where TargetObjectId=:setOfQuoteId];
	
	for(ProcessInstance pi:processinstance){
      //I assume that your relationship API name is ProcessInstanceStep__c
      ActorId.add(pi.ProcessInstanceStep__r.ActorId); // Error is here
		//ActorId.add(pi.ActorId);
	}
