To get the privileges assigned to only a materialized view in Oracle, you can use the following query:
SELECT grantee, privilege FROM dba_tab_privs WHERE table_name = 'your_materialized_view_name';
This query will display the users or roles that have been granted privileges on the specified materialized view. You can also replace 'dba_tab_privs' with 'user_tab_privs' if you want to see the privileges assigned only to the current user. By examining the output of this query, you can determine who has access to the materialized view and what specific privileges they have been granted.

How to grant execute privilege on materialized view in Oracle?
To grant execute privilege on a materialized view in Oracle, you can use the following SQL statement:
1
|
GRANT SELECT ON <materialized_view_name> TO <user_name>;

Replace <materialized_view_name> with the name of the materialized view you want to grant execute privilege on and <user_name> with the name of the user or role to whom you want to grant the privilege.
Keep in mind that granting the SELECT privilege on a materialized view will allow the specified user to query the data stored in the materialized view.
How to audit privileges on materialized view in Oracle?
You can audit privileges on materialized views in Oracle by using the following steps:
- Connect to the Oracle database using a privileged user account with the necessary permissions to audit privileges.
- Enable auditing for the materialized view by executing the following SQL query: AUDIT SELECT, INSERT, UPDATE, DELETE ON ;
- Verify that the auditing is enabled for the materialized view by querying the DBA_AUDIT_OBJECT view: SELECT * FROM DBA_AUDIT_OBJECT WHERE OBJECT_NAME = '';
- Monitor the audit records to track the privileges that are being exercised on the materialized view by querying the DBA_AUDIT_TRAIL view: SELECT * FROM DBA_AUDIT_TRAIL WHERE OBJ_NAME = '';
- Review the audit records regularly to ensure that only authorized users are accessing and modifying the materialized view.
By following these steps, you can effectively audit privileges on materialized views in Oracle to ensure the security and integrity of your data.
How to assign specific privileges on materialized view in Oracle?
To assign specific privileges on a materialized view in Oracle, you can use the GRANT statement. Here is an example of how to assign specific privileges on a materialized view:
- Connect to the Oracle database using a user with the necessary privileges to grant permissions (e.g. the DBA user).
- Use the GRANT statement to assign specific privileges on the materialized view. For example, to grant SELECT privileges on a materialized view named "mv_sample" to a user named "user1", you can use the following SQL statement:
1
|
GRANT SELECT ON mv_sample TO user1;
|
This statement grants the user "user1" the SELECT privilege on the materialized view "mv_sample".
- You can also grant other privileges such as INSERT, UPDATE, DELETE, or ALL privileges using the same GRANT statement. For example, to grant the user "user1" INSERT privilege on the materialized view "mv_sample", you can use the following SQL statement:
1
|
GRANT INSERT ON mv_sample TO user1;
|
- Make sure to commit the changes after granting the privileges:
1
|
COMMIT;
|
By following these steps, you can assign specific privileges on a materialized view in Oracle.
