One of HQL's greatest features is the implicit
JOIN feature, which is generated from path expressions when you follow foreign key "paths" from child entities to parent entities. The same feature is available in jOOQ as well, if you're using code generation.
In HQL, you might write:
from Book as book where book.language.cd = 'en'
And in jOOQ, this just translates to:
create.selectFrom(BOOK) .where(BOOK.language().CD.eq("en")) .fetch();
Some of the jOOQ features used in this section are:
- implicit joins (these are optional to the task of nesting, but greatly simplify it)
