Updating and deleting with query field lists
For queries, especially those attached to a browse widget, there is little concern about updates and deletes, because the complete results list for a query is built before any updates or deletes take place. In this case, updates and deletes are selective over the entire query. Therefore, field lists can greatly enhance query performance, no matter how many updates or deletes a browse user completes.
