Rewrite the all_source view, and I believe the all_objects view.

It's a pain in the rear, but it can be done.

It also tends to break when you upgrade.

I did this once on Oracle 7, there may be some other workaround now on 8i.

        Subject:        Read Only Login with Source Visibility

Hi all,

I am trying to create a read-only login, RO_USER which can do the following:

See all tables, views, constraints etc. in one *specific* other schema, APP.
See all the source for PL/SQL objects in APP.

The first bit is easy: GRANT SELECT on tables, views to RO_USER.

Not sure about the second bit. I have tried granting CREATE ANY PROCEDURE

and CREATE ANY TRIGGER to RO_USER and using a DDL trigger to prevent these

privileges actually being used to create procedures/triggers. This works but does not restrict the source visibility to APP. I have other schemas where I do not want RO_USER to see the source.

My other concern is granting SELECT on sequences as this means that they can select nextval from them and hence increment the numbers (not quite read-only!)

Any suggestions for fixing these problems would be much appreciated!

Thanks
- Bill.

PS. This is on 8i.
