Hi Team,

I have one security related issue.There are two users U1 and U2. Actually all the objetcts are resided in U1 schema and for U2 only CREATE SESSION privilege has been granted to him. Now, say U1 has granted SELECT privileges to U2 and he is able to SELECT objects as <owner_name>.<object_name> Ex.U1.<tname>. I am also getting results even. Now i just tried to qry the info regarding from which i have got the privileges to access other users objects. So i issued the SQL qry as SELECT * FROM USER_TAB_PRIVS; bUT i am not able to see what all privileges granted to me. Howcome this happen. Is there any security related Logic behind this. Because what i feel is that if anybody grants any privileges those privileges have to be get displayed in USER_TAB_PRIVS.

Thanks in advance,

What version of the database are you using? Seems to work fine on 9i:
SQL> conn test/test
SQL> grant create session to test_user identified by test_user;

Grant succeeded.

SQL> create table testtab (a1 number, a2 varchar2(20));

Table created.

SQL> grant select on testtab to test_user;

Grant succeeded.

SQL> conn test_user/test_user
SQL> select * from test.testtab;

no rows selected

SQL> select * from user_tab_privs;
