Question

The situation is I have two schemas: A and B. I have a restricted user that I need to give a privilege do SELECT queries in B schema and just it. How can I grant this user?

Answer 1

You can’t.

The best you can do is grant user a ‘select’ privilege each table in schema b.

this query will generate the commands you’ll need:

select 'grant select on A.'||table_name||' to B;' 
from dba_Tables 
where owner = 'A';

The problem with this, is in the case you will want to add new table to A. then you’ll have to grant the privilege on it separately. it will not do it automatically..
