I have created a new user using the below in sql developer (Oracle 11g). I have only two tables titled FEED_DATA_A and FEED_DATA_B that I want this user to be able to select, update and insert into. Can someone help me understand the SQL to create the proper privileges to accomplish that? I'm currently logged in as the system user.
CREATE USER "USER_A" IDENTIFIED BY "test123";
If you want to grant the privileges directly to the user
GRANT select, update, insert
ON table_owner.feed_data_a
TO user_a;
GRANT select, update, insert
ON table_owner.feed_data_b
TO user_a;
More commonly, though, you would create a role, grant the role to the user, and grant the privileges to the role. That makes it easier in the future when there is a new user created that you want to have the same privileges as USER_A to just grant a couple of roles rather than figuring out all the privileges that potentially need to be granted. It also makes it easier as new tables are created and new privileges are granted to ensure that users that should have the same privileges continue to have the same privileges.
CREATE ROLE feed_data_role;
GRANT select, update, insert
ON table_owner.feed_data_a
TO feed_data_role;
GRANT select, update, insert
ON table_owner.feed_data_b
TO feed_data_role;
GRANT feed_data_role
TO user_a

Three days ago, I created another user, it's ok. Now I create another user, not working. I don't know what I missed.
This time I did:
CREATE USER TESTDB identified by N2dTlOBFRZ9x;
GRANT CONNECT, RESOURCE TO TESTDB;
GRANT CREATE SESSION TO TESTDB;
GRANT UNLIMITED TABLESPACE TO TESTDB;
GRANT CREATE TABLE to TESTDB;
GRANT CREATE VIEW to TESTDB;
I can create a view, named viewTest, save it.
TESTDB viewTest
select * from PRODDB.employee
Then open viewTest, it says insufficient privileges.
I have another user. let's call it PRODDB. This is online database
The user I created 3 days ago, is OKDB.
Today I created one another, TESTDB.
In OKDB, I created a view (viewTest) and I can open it.
select * from PRODDB.employee;
But in TESTDB, cannot open.
Thank you for the update! I believe this is a permissions issue.
In OKDB, I created a view and I can open it. select * from
PRODDB.employee;
But in TESTDB, cannot open.
So in this example, there are three users: 1. PRODDB, 2. OKDB, and 3. TESTDB.
The view is named Employee and was created under the PRODDB schema; PRODDB.EMPLOYEE.
If OKDB can query PRODDB.EMPLOYEE, one of two things have to be true. Either: 1. OKDB was granted privileges on PRODDB.EMPLOYEE directly (e.g. grant select on PRODDB.EMPLOYEE to OKDB;), or 2. OKDB has elevated privileges through a role that enables the user to query that view (e.g. grant DBA to OKDB, which will allow OKDB to query any table in the database.)
If TESTDB can't query the view, I would bet that the necessary privileges have not been granted to the user. To fix this, I would recommend checking the privileges and roles that have been granted to the OKDB user and then granting the same privilege(s) to TESTDB. If this is something work related, you may have to work with another DBA if you do not have permission to issue grants.
It is possible to make grant select on dba_users to role? I trying to give access for users and all works fine, but when i try to do this for all group, this access didnt work.
Privileges which are granted through a role do not apply inside PL/SQL blocks. You have to grant the privilege to each USER individually.
See How Roles Work in PL/SQL Blocks
I want to create a view in SCHEMA_A using columns from a table LICENSE in SCHEMA_B.
create view SCHEMA_B.V_TEST as
SELECT LICENSE_NUMBER FROM SCHEMA_A.LICENSE L
then
select * from SCHEMA_B.V_TEST
This is giving me "ORA-01031: insufficient privileges" when I try to select from the view as the admin account. (Edit: admin account has SELECT ANY TABLE privileges.) What am I missing?
There is a similar question but the solution has to do with one user granting select to another. Since I'm admin I should have select privilege on both schemas already? However I have tried adding the line "GRANT SELECT ON SCHEMA_A.LICENSE TO admin_account WITH GRANT OPTION" and get the same error.
I think that the creation of the view fails, because schema_b doesn't have select privilege to schema_a.licence. Since you're creating an object in the schema_b, schema_b must have the necessary privilege.
Grant it:
as schema_a (or an DBA - "admin account")
grant select on schema_a.licence to schema_b
then you should be able to create the view and then select from it.
I have created a new database user. I found that the account can select data of other schemas' tables. So how can I restrict the new account to only manipulate its owned tables?
You can't. You can use REVOKE in certain cases but the most important thing to remember about REVOKE is that it can only revoke a permission that was explicitly GRANTed. Every database has GLOBAL permissions not tied to any specific schema and granted to PUBLIC. These permissions are inherited by all ROLES as long as they (the permissions) are in effect.
You can revoke certain PRIVILEGES such as SELECT, DELETE, INSERT etc. but you have to do it on an object level for every schema. What this means is, if a new table gets added to any of these schemas, the user will by default have access to it, unless the PRIVILEGES on that new table for that user are REVOKED.
As per Oracle documentation below are pre-requisites to REVOKE-
Prerequisites
To revoke a system privilege, you must have been granted the privilege with the ADMIN OPTION.
To revoke a role, you must have been granted the role with the ADMIN OPTION. You can revoke any role if you have the GRANT ANY ROLE system privilege.
To revoke an object privilege, you must previously have granted the object privilege to the user and role or you must have the GRANT ANY OBJECT PRIVILEGE system privilege. In the latter case, you can revoke any object privilege that was granted by the object owner or on behalf of the owner--that is, by a user with the GRANT ANY OBJECT PRIVILEGE. However, you cannot revoke an object privilege that was granted by way of a WITH GRANT OPTION grant.
I am logging into oracle as a simple user.I want other user who are logged in to the same database as i am ,be able to see and manipulate tabels and stored procedure.
I used grant privilege to achieve this.
grant all on tablename to user;
but it is not working ie on querying the table it is showing no such table or view exists.
How should i achieve this.
The other user may have to use a schema name when accessing the table. eg. select * from user1.table1
