Why can't an owner create a view? There is a user as HRS. I am creating a view in HRS as 

CREATE VIEW HRS.RNS.....


I am getting 


  ORA-01031: insufficient privileges


Edit

As i remember, i only execute following commands for the user and then my user can create tables

GRANT UNLIMITED TABLESPACE TO THE_USER;
GRANT CONNECT, RESOURCE TO THE_USER;
GRANT CREATE SESSION TO THE_USER;


How does my user automatically get rights to create table but not view?
You can create tables because the RESOURCE role has the CREATE TABLE privilege granted. To create a view, you need to have granted the CREATE VIEW privilege additionally, because, by default that privilege is not granted, not even to RESOURCE.

SQL&gt; select privilege from dba_sys_privs where grantee='RESOURCE';

PRIVILEGE
----------------------------------------
CREATE TRIGGER
CREATE SEQUENCE
CREATE TYPE
CREATE PROCEDURE
CREATE CLUSTER
CREATE OPERATOR
CREATE INDEXTYPE
CREATE TABLE


So you need to do the below:

grant create view to hrs;
