How can I encrypt a field in a Oracle table ( Oracle 8i) so that apart
from any specific user it will show the encryted figure to the rest
while browsing the table ?

I am not sure of any way you can deside to show a column to one user
but not another on 8i. With 10g you could use VPD (FGAC). You might
be able to use a paramaterized view referencing a global package
variable but what you can do depends on your environment.

With Oracle 8i pull your Supplied Packages and Types manual and look
at package DBMS_OBFUSCATION_TOOLKIT.

You should be able to articles on using this package via a web search.

Again I am not sure you will be able do do what you want or not.

You could define a view with the same name for each user you want to
allow or restrict access to the column substituting NULL instead of
the column for the no see set. This is really probably only practical
if you have one of the two sets being very small in number.
