Your windows don't really slide; they are fixed.<br><br>It's probably better to add an order event's value into a fact OrderPerHour, where you have one such fact for each hour, doing this when the event appears in the system. (Use no-loop on this rule.)<br>
<br>Then, using cron timers, inspect the OrderPerHour fact of the completed hour.<br><br>-W<br><br><div class="gmail_quote">On 8 July 2011 09:13, Amila Suriarachchi <span dir="ltr"><<a href="mailto:amilaSuriarachchi@gmail.com">amilaSuriarachchi@gmail.com</a>></span> wrote:<br>

based on message length based. But can I write a query with specific time<br>
intervals?<br>
<br>
For an example Lets say my CEP engine recive events which has order value.<br>
Now I want to fire an event if the orders within 8.00 am to 9.00 am have<br>
less than $40000. In generally firing an event if there are less that $40000<br>
total order value within any working hour (i.e 8.00 am 5.00 pm)<br>
<br>
is it possible to do this?<br>
