I have a list of objects I am querying and I am sorting it by start__c field which is a Date/Time type.
List<Notification__c> notifs = [SELECT id FROM Notification__c
WHERE Read__c=false ORDER BY Start__c DESC];
When the Date/Time field is different it is working as expected displaying in the descending order. But if the start__c is same for all Notification list,it is displaying in an unordered list.
What is the order in that case?
