1.2.1 Database Compatibility
Oracle Graph Server and Client works with Oracle Database 12.2 onwards on both on-premises and cloud environments. The cloud environment includes working with all versions of Oracle Autonomous Database (shared) and Oracle Autonomous Database (dedicated).
However, modifying a property graph using a PGQL INSERT,
                UPDATE, or DELETE query is not supported for
            Oracle Database 12.2.
