You can use the standard technique for that -- hide your sensitive
columns under a view, something like
...
SELECT pkey
, DECODE(SYS_CONTEXT('CTX$SEC', 'ROLE')
, 'CEO', col1
, 'MANAGER', col1
NULL
) col1
...
Where ctx$sec role is a application role based
Hi,
Unrelated question : If the system tablespace is so big would it not hurt performance for queries to all_tables, v$session, dba_segments etc. In such a case : can tables like source$be moved out of system tablespace and would it make sense. Thank YouVladimir Begun [EMAIL PROTECTED] wrote:

A Joshi,
Big/huge segments do not hurt performance, they only consume
space. Some queries (operations) against big segments can lead
to performance problems. So, I do not think that one should
consider segment's size as an immediate performance problem.
v$session is not a segment you should worry
how would i write a policy which retuns selected columns if the user has
issued select * from tab ???
using views for each user would work, but then.. i would end up with
so many views in the main schema !!! ;-(

You can't. Because in describe phase of query, sys.col$ is queried to get
column names and datatypes. And this always returns all columns that
physically exist in a given table (except

You would better count how much space those views' definitions
consume in your system tablespace. :)

Hi!
The views are small part. There are over 15 objects in whole database,
of which over 22000 are packages. System TS is about 4GB. (source$ table is
1.2GB, total of IDL_ tables is also about 1.2G).
