I have about 150 databases that I need to run a query in to find out if certain
users exists or better yet do not exists.
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?
