OBJECT_ID Pseudocolumn
The OBJECT_ID
pseudocolumn returns the object identifier of a column of an object table or view. Oracle uses this pseudocolumn as the primary key of an object table. OBJECT_ID
is useful in INSTEAD
OF
triggers on views and for identifying the ID of a substitutable row in an object table.
Note:
In earlier releases, this pseudocolumn was called SYS_NC_OID$ . That name is still supported for backward compatibility. However, Oracle recommends that you use the more intuitive name OBJECT_ID . |
