How create hibernate association by id?
<p>Here is a <code>Client</code> instance with <code>id</code> and <code>Order</code> instance with <code>clientId</code>. Is there a way to perform left join <code>Order</code> to <code>Client</code> without adding any fields for <code>Order</code>?
Result SQL shoul be like that:</p>

<pre><code> Select * from Client left join Order ON Order.clientId = Client.id
</code></pre>

<p>Note that <code>Order.clientId</code> may be null. Is there tricks to that with hibernate?</p>
