Function PreparedImpl.query
Execute a prepared SQL SELECT command where you want to deal with the result set one row at a time.
If you need random access to the resulting Row elements,
simply call std
on the result.
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.
