My database has two schemas, one with the actual tables and one that is used by an application. The application schema doesn't have any privileges on the actual tables. Instead there is a view for each table that limits the rows the application schema sees (but not the columns, the view is created as
SELECT * FROM ...). For all those views
DELETE was granted to the application schema.
If the application user does an insert into the view and violates a not null constraint, no column name is given. The actual error message is
ORA-01400: cannot insert NULL into (???).
I see that this makes sense from a security standpoint, but I don't care if the application user can see the name of the column of the actual table since it's always the same as the column name in the view. If it isn't possible otherwise, it would even be OK for me if the application schema sees the table name. Is there some privilege that can be granted that allows seeing the column name without allowing any actual queries on the table?
