    <p>I have the fallowing mapping:</p> <pre><code>&lt;class name="Country" table="Country" lazy="false" &gt; &lt;cache usage="read-write"/&gt; &lt;id name="Id" column="Id" type="Guid"&gt; &lt;generator class="assigned"/&gt; &lt;/id&gt; &lt;property name="Name" column="Name" type="String" length="50" not-null="true" unique="true" /&gt; &lt;set name="LocalizedProperties" where="LocalizedEntityClass = 'Prayon.Entities.Country'" cascade="delete"&gt; &lt;key column="EntityId" foreign-key="none" /&gt; &lt;one-to-many class="LocalizedProperty" /&gt; &lt;/set&gt; &lt;/class&gt; </code></pre> <p>LocalizedProperty is declared as follows:</p> <pre><code>&lt;class name="LocalizedProperty" table="LocalizedProperty"&gt; &lt;cache usage="read-write"/&gt; &lt;id name="Id" column="Id"&gt; &lt;generator class="guid.comb"/&gt; &lt;/id&gt; &lt;property name="CultureName" not-null="true"/&gt; &lt;property name="PropertyName" not-null="true"/&gt; &lt;property name="PropertyValue" not-null="true"/&gt; &lt;any id-type="Guid" name="Entity"&gt; &lt;column name="LocalizedEntityClass" not-null="true"/&gt; &lt;column name="EntityId" not-null="false"/&gt; &lt;/any&gt; &lt;/class&gt; </code></pre> <p>Now I try to create a select with hql which should return all Countries, with the fallowing "normal" SQL-Select</p> <pre><code>select * from Country a where ( select top 1 PropertyValue from LocalizedProperty x where x.EntityId = a.Id and x.PropertyName = 'Name' and x.LocalizedEntityClass = 'Prayon.Entities.Country' and x.CultureName = 'de') Like 'a%' </code></pre> <p>When I create the hql like </p> <pre><code>from Country a where ( select PropertyValue from LocalizedProperty x where x.EntityId = a.Id and x.PropertyName = 'Name' and x.LocalizedEntityClass = 'Prayon.Entities.Country' and x.CultureName = 'de' take 1) Like :val </code></pre> <p>and set the parameter val to a%</p> <p>I get the following <code>QueryException</code>:</p> <blockquote> <p>could not resolve property: EntityId of: Prayon.Entities.LocalizedProperty [from Country a where (select PropertyValue from LocalizedProperty x where x.EntityId = a.Id and x.PropertyName = 'Name' and x.LocalizedEntityClass = 'Prayon.Entities.Country' and x.CultureName = 'de' take 1) Like :val]</p> </blockquote> <p>I hope someone can help me how to setup my hql.</p>

Guidance
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.
