Function PreparedImpl.querySet
Execute a prepared SQL SELECT command where you expect the entire result set all at once.
This is being considered for deprecation in a future release of mysql-native,
	because the same thing can be achieved via query().
	array().
	If the SQL command does not produce a result set (such as INSERT/CREATE/etc),
	then mysql will be thrown. Use
	exec instead for such commands.
If there are long data items among the expected result columns you can use the csa param to specify that they are to be subject to chunked transfer via a delegate.
