I'm going to show my ignorance here, but would a materialized view help if there's a lot of transactional volume on the table e.g. if there are, say, 500 or so updates per hour across that table? Wouldn't I need to refresh the view every few seconds to keep it current? Or is this the part I'm missing? Received on Sun Apr 13 2008 - 14:54:45 CDT
