Are you referring to give grants based on columns. You could use ON COLUMN
syntaxt in the grant statemetnt for INSERT, REFERENCES, UPDATE.
If this is not acceptable, then other option is using views for each user
type and based on the user's priviege type. For instance, you may have a
table called CREDIT_CARDS, and you want to display the card numbers if the
user is a manager, just last 4 digits if analyst and nothing, if anybody
else.
create view ..
as
select ...,
decode(emp_type,
'MANAGER',cc_num,
'ANALYST',substr(cc_num,13,4),
null) cc_num
from CREDIT_CARDS cc, EMP e
....
Join this with VPD and you just got yourself a dynamic view which presents
information selectively.
