Write a trigger on contact to prevent duplicate records based on Contact Email & Contact Phone.But I want Indivizual Error detection,I did like below
--------------------------------------------------------------------------------------
Heleper Class:-
==========
public class ContactHelper {
//Write a trigger on contact to prevent duplicate records based on Contact Email & Contact Phone.But I want Indivizual Error detection
public static void PreventDuplicateContacts(list<contact> conList){
list<string> dupEmail =new list<string>();
list<string> dupPhone =new list<string>();
list<contact> EmailList = new list<contact>();
list<contact> PhoneList = new list<contact>();
for(contact c:conList){
dupEmail.add(c.Email);
dupPhone.add(c.Phone);
}
EmailList = [SELECT Id,Email FROM Contact WHERE Email =:dupEmail];
PhoneList = [SELECT Id,Phone FROM Contact WHERE Phone =:dupPhone];
for(contact c:conList){
if(EmailList.size()>0){
c.Email.addError('Email id already exists');
}
if(PhoneList.size()>0){
c.Phone.addError('Email id already exists');
}
}
}
}
Handler Class:-
==========
public class ContactHandler {
public static void PreventDuplicateContacts(){
ContactHelper.PreventDuplicateContacts(Trigger.new);
}
}
Trigger Code:-
=========
trigger ContactTrigger on Contact (Before insert,Before Update) {
if(Trigger.isInsert){
ContactHandler.PreventDuplicateContacts();
}
else if(Trigger.isUpdate){
ContactHandler.PreventDuplicateContacts();
}
}

You need to write Handler and helper. Both are same you can directly write the trigger code as below.
You can remove Handler class entirely.
I did not find any issues other than this.
trigger ContactTrigger on Contact (Before insert,Before Update) { if(Trigger.isInsert || Trigger.isupdate ){ ContactHelper.PreventDuplicateContacts(Trigger.new); } }Let me know if you face any issues.
Thanks,

Thanks Sai for your reply 🙂
yes I dont see any issues in the code inside the helper.
You can mark the above asnwer as best answer so it helps others.
