OBJECT_VALUE

The OBJECT_VALUE pseudocolumn returns system-generated names for the columns of an object table, XMLType table, object view, or XMLType view. This pseudocolumn is useful for identifying the value of a substitutable row in an object table and for creating object views with the WITH OBJECT IDENTIFIER clause.

Note:

In earlier releases, this pseudocolumn was called SYS_NC_ROWINFO$. That name is still supported for backward compatibility. However, Oracle recommends that you use the more intuitive name OBJECT_VALUE.
