Static Data Dictionary Views

This chapter contains descriptions of data dictionary tables and views. To see the data dictionary views available to you, query the view DICTIONARY.

See Chapter 3, "Dynamic Performance (V$) Views" for descriptions of the V$ views.

In Trusted Oracle Server, each of the dictionary tables and views contains a column that indicates the label of each row in the table or view. Trusted Oracle also provides some additional dictionary tables and views, and some Oracle8 dictionary tables and views contain columns that support compatibility with Trusted Oracle applications.

See your Trusted Oracle documentation for more information about Trusted Oracle dictionary tables and views.

Data Dictionary Views

The following is an alphabetical reference of the data dictionary views accessible to all users of an Oracle Server. Most views can be accessed by any user with the CREATE_SESSION privilege.

The data dictionary views that begin with DBA_ are restricted. These views can be accessed only by users with the SELECT_ANY_TABLE privilege. This privilege is assigned to the DBA role when the system is initially installed.
