[Archived move] Privilege Problem(create view)

I’d like to get all my Oracle knowledge back, ’cause I lost almost 2 years.
It’s a little hard for me now, ’cause I study these after work.

I create a user miloluo with connect and resource roles.

SQL> create user miloluo identified by miloluo;

User created.

SQL> grant connect, resource to miloluo;

Grant succeeded.

SQL>

All seems to be ok, but when I create several tables and create the view problem occured:

SQL> create view v_empdept as
2 select dname, ename, sal from emp left outer join dept using(deptno);
create view v_empdept as
*
ERROR at line 1:
ORA-01031: insufficient privileges

So it should have not permission on creating view, after search the document lib, I finally find the privilege I should grant to user miloluo.
http://download.oracle.com/docs/cd/B19306_01/server.102/b14196/users_secure002.htm#sthref415

so again, grant this privilege to miloluo

SQL> grant create view to miloluo;

Grant succeeded.

And view created sucessfully,

SQL> create view v_empdept as
2 select dname, ename, sal from emp left outer join dept using(deptno);

View created.

SQL> select * from v_empdept;

To solve this problem, I googling the “ORA-01031: insufficient privileges create view”.
I found the first item of result it’s about a user(user A) create view on another user’s(user B) table, even though B got the grant on that table with a new role.
A still can’t create the view unless directly grant the create view on B’s table.
It’s very interesting, I will add this topic later.
