Tiny little enhancement in Oracle Database 184.108.40.206:
The new CONTAINER clause to access data from different containers within one SQL statement. This may be very helpful, especially in case of schema consolidation. Similar things could have be done in Oracle 220.127.116.11 already by using database links – but resulting in way more complicated SQLs.
This is the new clause:
SELECT ename FROM CONTAINERS(scott.emp) WHERE CON_ID IN (45, 49);
See the documentation for more info about it.
