Just a quick one. I've advised a customer of the complications of using domain logins for database owners, and they've agreed to change the owner to sa for all databases where necessary. So, in prep for said change, I wrote a quick query to list all databases with owners, so I could see which ones required changed. This statement will return back your databases w/owners for quick review.
SELECT
name
[Database],
suser_sname(owner_sid) [Owner]
FROM
sys.databases
WHERE
database_id > 4
