How to create an account w/o having to specify object owner_names

Question

Hi,
Do you know how to create an account, that, when logged in wouldn't need to use the following syntax when referring to objects: select * from <owner_name>.<object_name>.
When the owner of the account creates an object, then obviously, it's not necessary to specify the owner_name (syntax: select * from <object_name>;), but, I'd like an account with ie: (username: joey) to not have to specify the owner_name for all the objects owned by another owner (ie: bob).
Is this possible?
Thanks.

Answer 1

This is one use for SYNONYMs. You can create a private synonym for JOEY:
create synonym joey.table_a for bob.table_a; or a public synonym:
create public synonym table_a for bob.table_a;public synonyms mean everybody can seen the table without prefixing it with the owner; but PUBLIC synonyms, like PUBLIC grants, make fine-grained security access harder to achieve.
In the first case the account creating the synonym must have rights on BOB's tables and (unless the account creating the synonym is JOEY) the CREATE ANY SYNONYM privilege. In the second case they must have rights on Bob's tables and CREATE PUBLIC SYNONYM privilege.
In both cases the account must either be BOB or have been granted access to BOB's tables: if the creating account is not JOEY they must have been granted the privileges WITH ADMIN option: it's no good having a synonym on BOB's table_a if you don't have the privilege to select from it. This is important because it is possible to create a synonym for an object you don't have rights on or indeed that doesn't exist.
I hope that's clear.
