TIMESTAMP VARCHAR2(19)   Timestamp for the specification of the object (character data)
STATUS VARCHAR2(7)   Status of the object:


  • N/A

TEMPORARY VARCHAR2(1)   Indicates whether the object is temporary (the current session can see only data that it placed in this object itself) (Y) or not (N)
GENERATED VARCHAR2(1)   Indicates whether the name of this object was system-generated (Y) or not (N)
SECONDARY VARCHAR2(1)   Indicates whether this is a secondary object created by the ODCIIndexCreate method of the Oracle Data Cartridge (Y) or not (N)
NAMESPACE NUMBER NOT NULL Namespace for the object
EDITION_NAME VARCHAR2(128)   Name of the edition in which the object is actual
SHARING VARCHAR2(13)   Values:
  • METADATA LINK - If the object is metadata-linked or a metadata link to an object in the root

  • OBJECT LINK - If the object is object-linked or an object link to an object in the root

  • NONE - If none of the above applies

  • Y - For objects marked EDITIONABLE

  • N - For objects marked NONEDITIONABLE

  • NULL - For objects whose type is not editionable in the database

ORACLE_MAINTAINED VARCHAR2(1)   Denotes whether the object was created, and is maintained, by Oracle-supplied scripts (such as catalog.sql or catproc.sql). An object for which this column has the value Y must not be changed in any way except by running an Oracle-supplied script.
