HP-UX11/Oracle 8.1.6/Constraint Question

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
