OpportunityContact角色数据访问

Question

我试图从一个opportunitycontactrole得到一个人的名字......是可能的或完全脱离基地？这是我已有的代码。我知道从contactRole获取联系人ID并没有返回一个名字......我需要在那里得到一个名字，而不是我的名字？

trigger add_primary_advisor on Opportunity(before update) { 

for(Opportunity o: Trigger.new){ 

    if (!Trigger.oldMap.get(o.id).IsClosed) { 
     OpportunityContactRole contactRole = 
      [select ContactID from OpportunityContactRole where IsPrimary = true and OpportunityId = :o.id]; 
     if (contactRole != null) { 
     o.Primary_Advisor__c=contactRole.contactID; 
     } 
    } 
    }  
} 

Answer 1

//If Contact.Name doesn't works try fetching Contact.FirstName, Contact.LastName 
    List<String> names = new List<String>(); 
    for(OpportunityContactRole contactRole = 
     [select Contact.Name from OpportunityContactRole where IsPrimary = true and OpportunityId = :o.id]){ 
     names.add(contactRole .Contact.name) 
    }
