+                    This will return a single row of results with 2 values, the maximum price and the minimum price of

+                    JDO 2 introduces the ability to use aggregates in queries. Here's another example using the 
+                    same Product class as above, but this time looking for the maximum price of products that are 
+                    CD Players. Note that the result for this particular query will be of type Double since there 
+                    is a single double precision value being returned via the "result".
+                </p>
+    <div class="source"><pre>
+Declarative JDOQL :
+Query query = pm.newQuery(org.datanucleus.samples.store.Product.class);
+query.setFilter("name == \"CD Player\"");
+query.setResult("max(this.price)");
+List results = (List)query.execute();
+Iterator iter = c.iterator();
+Double max_price = (Double)iter.next();
+
+Single-String JDOQL :
+Query query = pm.newQuery("SELECT max(price) FROM org.datanucleus.samples.store.Product WHERE name == \"CD Player\"");
+List results = (List)query.execute();
+Iterator iter = c.iterator();
