    <p>I'm trying out the second level cache in NHibernate. With this code:</p> <pre><code>return session.Query&lt;Payment&gt;() .Cacheable() .OrderByDescending(payment =&gt; payment.Created) .Skip((page - 1)*pageSize) .Take(pageSize).ToArray(); </code></pre> <p>If the entities are not in the cache, it will lead to queries like these being executed: </p> <pre><code>select ... from Payment where Id = 1 select ... from Payment where Id = 2 select ... from Payment where Id = 3 </code></pre> <p>If 100 rows are returned, 100 of these would be executed. I.e. a big performance issue. It would be better if just this query was executed:</p> <pre><code>select ... from Payment where Id in (1,2,3) </code></pre> <p>That the entities doesn't exist in the cache can be because of no entity cache configured, limited size of the caches or that the entities in the cache has been expired or removed from the cache.</p> <p>To not be forced to rely 100% on the entity-cache, is it possible to change the way NHibernate queries for that "missing" entity data?</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.
