Do subclasses inherit private fields?
...
Think of it this way. Borat's father Boltok has a safe containing $100,000. He does not want to share his "private" variable safe. So, he does not provide a key for the safe. Borat inherits the safe. But, what good is it if he cannot even open it ? If only his

A join would produce a very big amount of data, that may not fit into memory and must be paged into the swap-file. Whenever this is the case the query-times...
