object graph. This allows you to map arbitrary SQL code to objects,
such as highly vendor-optimized SQL or stored-procedures.
Because writing ``ResultSetMapping`` is not so simple, there is a convenience

of this chapter describes its usage.

For entites with more columns the builder is very convenient to use. It extends the ``ResultSetMapping`` class
and as such has all the functionality of it as well. Currently the ``ResultSetMappingBuilder`` does not support
entities with inheritance.
