Changes in This Release for Oracle Database Object-Relational Developer's Guide

New Features

This release contains a new privilege READ, which is an alternative to the SELECT privilege. In addition to querying objects, the SELECT object privilege allows users to lock rows of a table with the LOCK TABLE and SELECT ... FOR UPDATE statements. The READ object privilege only allows users to query objects.
