New READ Object Privilege in 12cR1

The “SELECT” object privilege in addition to querying the table, allows the user to:
 
LOCK TABLE table_name IN EXCLUSIVE MODE;
SELECT… FROM table_name FOR UPDATE;

The New Feature of “READ” object privilege, does not allow the user to lock tables in exclusive mode nor select table for update.
Prior to 12.1.0.2, the “SELECT” object privilege is only available which allows the locking:

GRANT SELECT ON ... TO ...;

12.1.0.2 onwards, the new “READ” object privilege is available which doesn’t allow the locking:

GRANT READ ON ... TO ...;

This also applies to the “SELECT ON ANY TABLE“, prior to 12.1.0.2 which allows the locking:

GRANT SELECT ANY TABLE TO ...;

12.1.0.2 onwards, the new “READ ON ANY TABLE” object privilege is available which doesn’t allow the locking:

GRANT READ ANY TABLE TO ...;
