Update query does not replace with nothing ?

    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 ?

    Can you show us the query string that gets sent to the database when it fails?
