<p>I have a data object that collect log information from some DB tables. I would like to append data to it. Obviously I need to run my select query with some date parameter so it doesn't bring in everything every time I run it and I don't miss any records in case of scheduling issues. I could do it by creating some "control" table in the DB and use it to store the max timestamp for the next run. But I would like to have this functionality on the BIRT side. </p>
<p>Any suggestions?</p>
