Hi Akshay,

is it you just want to append  BeforeTrigger with your field execute__c on update operation ?  if so 

try below code 
trigger OrderOfExecutionBeforeTrigger on OrderOfExecution__c (before update)
{
   
  for(OrderOfExecution__c Oex : trigger.new)
    {
        
        Oex.execute__c = Oex.execute__c + ' BeforeTrigger';
        
    }
}

Let me know if you have other requirement on this.

If it helps ,mark it as best answer.
