    <p>Firstly, I have read <a href="https://stackoverflow.com/questions/9291969/hibernate-one-table-with-multiple-entities">Hibernate - One table with multiple entities?</a>.</p> <p>However, I would like to map two entities to the same table, but I would like both of them to be entities, which I can select from. What I mean:</p> <ul> <li>One table: Person (id, name, dateOfBirth, city, street, zipcode).</li> <li>Two Entities: Person (id, name, dateOfBirth), Address (id, city, street, zipcode).</li> </ul> <p>So it's a 1:1 relationship between Entities, but still 1 table in DB.</p> <p>If I do it using the proposed solution (component keyword) in the above link, I can't query Address directly (I can access it via Person entity). And I want to be able to do</p> <pre><code>session.createCriteria(Adres.class) </code></pre> <p>How do I do that?</p> <p>UPDATE: I tried the one-to-one association between entities, in Address mapping:</p> <pre><code>&lt;one-to-one name="Person " class="model_mapowanie_xml.Person "/&gt; </code></pre> <p>and in Person mapping:</p> <pre><code>&lt;one-to-one name="Address" class="model_mapowanie_xml.Address "/&gt; </code></pre> <p>Both classes have fields referring to the other one. Selecting records works fine for that. However, how can I add in one transaction a record using both entities? (Id is db-generated)</p> <pre><code>Address ad = new Address(); ad.setProperty("Sydney"); Person p = new Person(); p.setProperty("John"); p.setAddress(ad); session.save(p); </code></pre> <p>and only Person part is saved, the address property remains empty.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
