Try modifying your code as follows:

 

trigger duplicateGC on GL_Code__c (before insert,before update) {
List<GL_Code__c> lstGC = new List<GL_Code__c>();
if(Trigger.isInsert)
{
    for(GL_Code__c g:Trigger.New)
    {
        lstGC=[select id from GL_Code__c where Name =: g.Name];
        if(lstGC.size()>0)
        {
           for(GL_Code__c g1:lstGC)
               g.Name.addError('Duplicate Record');
              
        }
       
    }
}
else if(Trigger.IsUPdate)
{
for (GL_Code__c no : Trigger.new)
           {
              GL_Code__c old = Trigger.oldMap.get(no.id);
              if (no.Name != old.Name)
              {
                 lstGC = [select id from GL_Code__c where Name =: no.Name];
        
                 if (lstGC.size() > 0)
                 {
                    for(GL_Code__c noOld : lstGC)
                    {

                        no.Name.addError('Duplicate Record');

                     }
                 }
                 
              }
           }
           }
}

You would need to write a trigger for that object, which won't allow you to create a duplicate record with same Name

I am doing the same..

 

This is my code,

 

trigger duplicateGC on GL_Code__c (before insert,before update) {
List<GL_Code__c> lstGC = new List<GL_Code__c>();
if(Trigger.isInsert)
{
    for(GL_Code__c g:Trigger.New)
    {
        lstGC=[select id from GL_Code__c where Name =: g.Name];
        if(lstGC.size()>0)
        {
           for(GL_Code__c g1:lstGC)
               g1.addError('Duplicate Record');
              
        }
       
    }
}
else if(Trigger.IsUPdate)
{
for (GL_Code__c no : Trigger.new)
           {
              GL_Code__c old = Trigger.oldMap.get(no.id);
              if (no.Name != old.Name)
              {
                 lstGC = [select id from GL_Code__c where Name =: no.Name];
        
                 if (lstGC.size() > 0)
                 {
                    for(GL_Code__c noOld : lstGC)
                    {}
                 }
                 
              }
           }
           }
          
           if(lstGC.size() > 0)
       update lstGC;   

}

 

How can i display error message and avoid inserting a record if it is duplicate record?

                     }
                 }
                 
              }
           }
           }
}

Had you tried your code, I'm sure it will fail in case of bulk Update/Insert.

For bulk update try below code:

 

trigger AvoidDuplicateAccounts on Account (before insert, before update) 
{
 Set<String> setAccountName = new Set<String>(); 
 for(Account objAccount: [Select Name from Account])
  setAccountName.add(objAccount.Name);
 for(Account objAccount: Trigger.new)
 {
  if(!setAccountName.contains(objAccount.Name))
  {
   //   To handle bulk insert
   setAccountName.add(objAccount.Name);
  }
  else
  {
   objAccount.Name.addError('Account with same name Exists');
  }
 }
}

you should use Maps or Sets for that, as Map cant have duplicate records.

the above code will hit governer limits if you insert large number of records.
