You can put all the HQL into the XML mapping file rather than putting the sql queries to various places in between code.

sample.hbm.xml

<hibernate-mapping>
    <class name="com.test.Product" table="product">
        <id name="id" type="java.lang.Integer">
            <column name="ID" />
            <generator class="identity" />
        </id>
        <property name="code" type="string">
            <column name="CODE" length="10" not-null="true" unique="true" />
        </property>
    </class> 
    <query name="getProductByCode">
        <![CDATA[from Product p where p.code = :code]]>
    </query> 
</hibernate-mapping>

Now you can use it as below:

Query query = session.getNamedQuery("getProductByCode")
.setString("code", "101");
