Hello! I would like to specify my problem once again! I have a field type: VARCHAR(100) NOT NULL When I add new record in database everything works OK! When I want to modify data in a field using ADO with: RS.Fields(0).Value="Value" function everything works OK again when I use the same or less length value that it was before. (lets say when field value was "123" and change to "456" or "45" or "4") The problem is when I use greater length value (my sql respond as error) (lets say when field value was "123" and change to "4567") What should I do to avoid this problem? Thanks all! Simon
