14.4. Forms of join syntax
HQL supports two forms of association joining:
implicit
and explicit
.
The queries shown in the previous section all use the
explicit
form, that is, where the join keyword is explicitly used in the from clause. This is the recommended form.
The
implicit
form does not use the join keyword. Instead, the associations are "dereferenced" using dot-notation. implicit
joins can appear in any of the HQL clauses. implicit
join result in inner joins in the resulting SQL statement.
