Hi:

The structure is same and the results are also same when you connect as a DBA user. (DBA role granted user).

Where as you cannot view dba_tables with out having dba role. you can view user_tables and all_tables with normal user privilege. Here you will see the difference. The all_tables return only the user specific tables.

Thank you.
Srinath

USER_TABLES is tables which you own
ALL_TABLES is tables which own, and tables owner by other users, which you have been granted excplicit access to
DBA_TABLES is all tables in the database

All three are views of the underlying SYS tables, but the USER_ and ALL_ views joing in your username/security info to limit the results (the original VPD).

To be more clearer, all_tables shows you only the tables those are allowed for your previliges, where the dba_tables shows all the tables as dba is allowed view/change/delete any of them.
Hope this helps. Good luck :)
