I understand that database views are read-only, or at least read-only by default.
Is it possible to include a change in the data obtained as an oracle?
Paraphrasing: If I scan only one table, just to hide some columns, will the changes in this data be updated in the table?
Yes, Oracle views are subject to change.
However, there are some limitations:
, Oracle ... , , DISTINCT GROUP BY. , , UPDATE VIEW.
, ...
GRANT UPDATE ON your_view_name TO your_user;
UPDATE?
. , , .
, "" Oracle.

Additional information can also be found in the sql Create View command.
