OBJECT_VALUE Pseudocolumn
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 . |
