<p>Hello,</p>
<p>to have full flexibility here I am thinking of adding a new
module parameter to set the order-by string when the
retrieve_order=1, as it may be different for various db
connectors. The default will be 'priority', which is what is done
right now.</p>
<p>That will practically cover also the case of retrieve_order=0,
where the order by is done on received_time, but for backwards
compatibility I think it should stay there.</p>
Cheers,<br>
Daniel<br>

<p class="MsoNormal">Well, the priority is not known in advance,
query is like:<br>
<br>
select ... from presentity by matching the user and event,
ordering either by receive_time when retrieve_order=0 or by
priority if retrieve_order=1.<br>
<br>
Here it looks like order by has to be a combination of the two
columns.<br>
