    <p>I have written hql which work correctly in Hql editor but when I apply it in java code it give me Error.</p> <p>HQL Query which is working correctly</p> <pre><code>select auhority.id from Authority as auhority where auhority.action = 'USER_MASTER_FULL_ACCESS' and auhority.aclObject is NULL </code></pre> <p>Java Code for executing query</p> <pre><code>String hql = "from " + Authority.class.getCanonicalName() + " as model where model." + Authority.ACTION + " = ? and model." + Authority.ACL_OBJECT + " is null"; Query query = getSession().createQuery(hql); query.setParameter(0, action); List&lt;Authority&gt; list = query.list(); return list; </code></pre> <p>Here SecuredObject is ACL_OBJECT which is foreign key for Authority table which can be null. Otherwise other stuff ie add, update and delete is working correctly.

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.
