A "BEFORE INSERT" trigger would work. Use it to set the value of the field.

Mike,

Try using an 'instead of' trigger. It's made to purpose.

This is something I'm not sure can be done. Can somebody help me out?

I have a single table with a DEVICE_TYPE field, and four views - one for each valid device type. DEVICE_TYPE is a NOT NULL field. The views are defined like

   create view mytype_vw as
   select col1, col2, col3
   from table
   where device_type = 'MYTYPE';

DEVICE_TYPE is not displayed, it is inferred from the view. If I want to insert a row through the view, how can I populate the DEVICE_TYPE field?

TIA,
Mike
