Apologies in advance for making assumptions. Curious as to how you're planning to run this on all your dbs?

Try these:
- select * from all_users where username in ('user1', 'user2', 'user3');

- select count(1) from all_users where username in ('user1', 'user2', 'user3');

- select vi.instance_name, au.username
    from v$instance vi, all_users au
    where au.username in ('user1', 'user2', 'user3');

Then I would have to have that db_link in all of my databases? Can’t do that…

Thanks anyway

Not an sql expert and this is only an attempt:

select * from all_users@db_link
where username in (select * from all_users where username in ('user1', 'user2', 'user3'))
union all
..
..
..
order by username asc;

    I have about 150 databases that I need to run a query in to find

    I have 5 users ops$john, ops$dave, ops$mark, ops$ken, and
    ops$lee.  I need to run a SQL statement that would let me know if
any or all of those users do not exists in the all_users table. How do I write a SQL statement that would allow me to pass that
    list of users and list those that are not there.

    My boss is asking for a report like this and I have no idea how to
    write such a thing.  I have not written SQL in years and stumbling
    to provide an answer.

    Any SQL guru’s have suggestions?
