I am trying to build a trigger on Contact object. So, whenever a user enters a contact record, its related account name field gets updated with contact last name.

Please have a look at the code below: 

trigger addcontactlastname2accountname on Contact(before insert){

    Set<ID> contactid_lst = new Set<ID>();
    List<Account> account_lst = new List<Account>();
    Map<ID, Account> accountmap = new Map<ID, Account>();

    for(Contact c: Trigger.New){
        
        contactid_lst.add(c.AccountID);
    }

    account_lst = [Select ID, Name from Account where ID IN: contactid_lst];


    for(Contact c: Trigger.New){


        Account objacct = new Account();

        objacct = accountmap(account_lst).get(c.AccountID);
        
        objacct.Name = objacct.Name + '' + c.lastname;
        

    }

}

Hi Rahul,

please check once following code : 
  
trigger addcontactlastname2accountname on Contact(before insert){

    Set<ID> contactid_lst = new Set<ID>();    
    Map<ID, Account> accountmap = new Map<ID, Account>();

    for(Contact c: Trigger.New){
	    if(c.AccountID != null){
		   contactid_lst.add(c.AccountID);
		}
        
        
    }

    accountmap = [Select ID, Name from Account where ID IN: contactid_lst];


    for(Contact c: Trigger.New){
	  c.lastname = accountmap.get(c.AccountID).name;      

    }

}

Hope this helps you!

Thanks
