DBA Dictionary Views

Oracle requirements to query DBA views |
Your username must have one of the following roles or privileges:
DBA role and SELECT_CATALOG_ROLE role must be defined as the default roles in Oracle. In addition to the SELECT ANY TABLE privilege, Oracle 9i may also require the user to have the SELECT ANY DICTIONARY privilege if the O7_DICTIONARY_ACCESSIBILITY initialization parameter is set to FALSE. For information about system privileges, see the Oracle Database Administrator’s guide. |
|
|
Note: Enabling DBA dictionary views may affect performance for some Oracle instances, depending on the number of users and objects, as well as other environmental factors. |
How SQL Navigator handles the views
When DBA dictionary views are selected, SQL Navigator interrogates the data dictionary differently:
Regardless of DBA View setting, SQL Navigator uses USER_% views for the logged-on user's objects.
Without DBA Views, SQL Navigator uses ALL_% views for other user's objects.
With DBA Views, SQL Navigator uses SYS.DBA_% views for other user's objects.
