Suppose I have 10 Opportunities, out of which I have access to only 4 opportunities and I don’t have access on standard field of currency type – Amount filed on opportunity. If I perform SOQL query within an apex class which is running under With sharing mode to pull-out Opportunity Name and Amount. So how many records will return and what data I will see in amount?
