<para>
Using named SQL queries, you may also query for scalar values. To do this, use the type attribute
of the return element and specify a Hibernate type there:
</para>
<programlisting><![CDATA[<sql-query name="mySqlQuery">
<return alias="name" type="string"/>
<return alias="age" type="long"/>
SELECT p.NAME AS {name},
p.AGE AS {age},
FROM PERSON p WHERE p.NAME LIKE 'Hiber%'
</sql-query>]]></programlisting>
<para>
You can also use custom types and typedefs you defined in the type attribute (remember that
the mapping file containing the typedefs has to be added earlier to the configuration).
