HI Emma Watson ,

I think you Incident is the child object and Staff is a perent object like Contact and Account .
You want to fetch staff name in Incident query .Please check the query I have written for contact and Account .you think that contact is Incident and account is Staff .

SELECT Id,Account.Name FROM Contact .As staff is custom object what you need to write like

SELECT Id,Staff__r.Name FROM Incident__c
Please replace Staff with your Object API name and Incident with your API name .

Let   me know incase any isisue .

Thanks
Manoj

Thanks for update...

Here, Incident is an object which has a field named as 'Staff' which is lookup field(User). Staff is not an object here.

So, how to fetch the name of the staff field.
Below is the query that I have written to fetch, but it gives me an id of that staff where I need is a name of the staff.

List<BMCServiceDesk__Incident__c> inc=[SELECT name,BMCServiceDesk__incidentDescription__c,BMCServiceDesk__FKOpenBy__c 
                                         FROM BMCServiceDesk__Incident__c
                                         WHERE BMCServiceDesk__Category_ID__c='Hardware'];
       
        for(Integer i=0;i<inc.size();i++)
        {
            System.debug('Incident name is :'+inc.get(i).name);
            System.debug('Incident description is :'+inc.get(i).BMCServiceDesk__incidentDescription__c);
            System.debug('Incident staff is :'+inc.get(i).BMCServiceDesk__FKOpenBy__c);
        }

The bold one is what giving me Id of the staff but I want it as a name.
Please find the below screenshot for the output.
Staff Id is shown, where I need name of it.

Please suggest.
Thanks!

Hi Emma Watson ,

You need to add the Staff field API Name like Staff__r.Name in the query to get the name of the staff .

Let me know in case any issue .
