I have a problem that when I am trying to run select query say</p> <pre><code>"from Foo where Foo.some_id=2" </code></pre> <p>(with Hibernate template) then Hibernate is also tries to insert the records in a table 'Foo2' that has a one-2-one association with the Foo table </p> <p>Bean Foo</p> <pre><code>class Foo{ int id; .... Foo2 foo2; } </code></pre> <p>Foo.hbm.xml</p> <pre><code>... &lt;one-to-one name="foo2" class="Foo2" property-ref="foo" constrained="false" cascade="save-update"&gt;&lt;/one-to-one&gt; ... </code></pre> <p>Bean Foo2</p> <pre><code>Class Foo2{ ... private int foo; ... } </code></pre> <p>Foo2.hbm.xml</p> <pre><code>... &lt;property name="foo" column="foo_id"/&gt; ... </code></pre> <p>Usage </p> <pre><code> DetachedCriteria criteria = createDetachedCriteria(); criteria.add(Restrictions.eq("some_id", value)); return getHibernateTemplate().findByCriteria(criteria); public List&lt;SnsUser&gt; getAllSnsUsersByProperty(String prop, Object val){ String query = "from SnsUser su where su." + prop + " =:" + prop; return executeQuery(query, new String[]{prop}, new Object[]{val}); } public static void main(String[] args) { //WORKING String query = "from SnsUser su where su.blessUserId=1"; Session session = Utility.getSessionFactory().openSession(); List l = new SnsUserDaoImpl().getQRes(query); System.out.println(l); session.close(); } public List&lt;E&gt; executeQuery(String queryString, String []param, Object [] val){ //NOT WORKING return getHibernateTemplate().findByNamedParam(queryString, param, val); } </code></pre> <p>This is what i am getting...</p> <pre><code>Hibernate: select * from bless_aggregation.sns_user this_ left outer join bless_aggregation.sns_authenticator snsauthent2_ on this_.sns_uid=snsauthent2_.sns_uid where this_.bless_uid=?

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.
