    <p>Considering the following model:</p> <pre><code>@Entity public class User { @Id @Column(name = "USER_ID") private Long userId; @Column(name = "FIRST_NAME") private String firstName; @Column(name = "LAST_NAME") private String lastName; @OneToOne @PrimaryKeyJoinColumn private UserExt userExt; ... //getters and setters } @Entity public class UserExt { @Id @Column(name="USER_ID") private Long id; private String cdpId; private Date lastChanged; ... //getters and setters } </code></pre> <p>when executing :</p> <pre><code>Query query = session.createQuery("from User"); List&lt;User&gt; list = query.list(); </code></pre> <p>Hibernate executes </p> <pre><code>Hibernate: select user0_.USER_ID as USER1_0_, user0_.FIRST_NAME as FIRST2_0_, user0_.LAST_NAME as LAST3_0_, user0_.EXT_USERNAME as EXT4_0_ from USER user0_ Hibernate: select userext0_.USER_ID as USER1_1_0_, userext0_.cdpId as cdpId1_0_, userext0_.lastChanged as lastChan3_1_0_ from USER_EXT userext0_ where userext0_.USER_ID=? Hibernate: select userext0_.USER_ID as USER1_1_0_, userext0_.cdpId as cdpId1_0_, userext0_.lastChanged as lastChan3_1_0_ from USER_EXT userext0_ where userext0_.USER_ID=? ... ... </code></pre> <p>Using a query with specific properties works (select u.firstName, u.userExt.cdpId).</p> <p>However since I want the full User Entity ("from User"), hibernate generates one select for each result row in the first.</p> <p>I don't get it since the default fetch strategy should be LAZY not EAGER. Forcing it to LAZY didn't fix the problem.</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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
