14.17. Components
Components can be used similarly to the simple value types that are used in HQL queries. They can appear in the
select
clause as follows:
select p.name from Person p
select p.name.first from Person p
where the Person's name property is a component. Components can also be used in the
where
clause:
from Person p where p.name = :name
from Person p where p.name.first = :firstName
Components can also be used in the
order by
clause:
from Person p order by p.name
from Person p order by p.name.first
Another common use of components is in Section 14.18, “Row value constructor syntax”.
