This query works fine [SQL]UPDATE duration_events b JOIN meteor_events p ON p.event_id = b.event_id SET b.eventdes = p.eventdes; so if enter some text in meteor_events, eventdes for a particular record then the text in the corresponding record in duration_events get updated. How ever if I then remove the text from meteor_events, eventdes and run the query its not replaced in duration_events - i had assumed it would simple repace the contents of the field ? John B
