Hello

I'm trying to retrive data from the SQL filtering data. In a query it whould be something like this:
SELECT * FROM tale WHERE system = 'system' AND (time <= '2012-01-01 00:00:00' AND time >= '2012-02-01 00:00:00')

Currently I'm retriving the data like:
var adData:ArrayCollection = new ArrayCollection();
acData = ActiveRecords.table.findBySystem(system);

In this process I can't seen to put the clause in bold.
Does any one have any ideias on how to do this?

Thanks in advance, best regards
