My users where assigned CONNECT and RESOURCE roles. I'd like to give them insert, update, and delete priv's on their own tables.

When a user is created do they have these priv's on their objects already? I'm assuming I must also give them CREATE SESSION also?

thanks.

RESOURCE could be dangerous.
Grant a CONNECT and a explicit quota on the default tablspace assigned.
In 10g, things are little different.

Hi,

When a user is created do they have these priv's on their objects already?

Yes.

SQL> conn sys@orcl as sysdba
Enter password:
Connected.
SQL> create user boo identified by boo;

User created.

SQL> alter user boo default tablespace USERS quota 2m on users;

User altered.

SQL> GRANT CREATE SESSION TO boo;

Grant succeeded.

SQL> grant resource to boo;

Grant succeeded.

SQL> conn boo@orcl
Enter password:
Connected.
SQL> create table boo ( name varchar2(20));

Table created.

SQL> insert into boo values ('booo');

1 row created.

SQL> update boo set name = 'BOO';

1 row updated.

SQL> delete from boo;

1 row deleted.


If you grant RESOURCE role that is you grant below privs.
SQL> select * from session_privs;

PRIVILEGE
----------------------------------------
CREATE SESSION >>> explicit grant.
UNLIMITED TABLESPACE
CREATE TABLE
CREATE CLUSTER
CREATE SEQUENCE
CREATE PROCEDURE
CREATE TRIGGER
CREATE TYPE
CREATE OPERATOR
CREATE INDEXTYPE

10 rows selected.

>> CREATE SESSION >>> explicit grant.
Actually, that is implicit.

Actually i don't understand your reply.
on my previous example i grant RESOURCE role or CREATE SESSION two privs to user.

that is why i indicate EXPLICIT for create session privs.

I saw one example where you created a table. This I don't want them to do. I already have users creating views and tables and then running extremely long queries that are tying up system resources.

What I should of asked in the beginning is "What do you normally let your users do OR what privs do you give them?"

Hi,
What do you normally let your users do OR what privs do you give

It is depand on user requirement. according there work and need we grant privs.

but minimum privs you have to grant is "CREATE SESSION" through this user connect to database.
