My colleagues and I take schema ownership seriously. The owner (with few exceptions) should always be “dbo”. Certainly, it should not be a user. Why? Because if the user leaves and their account is disabled or deleted, we have a problem. If you’re a DBA, you have enough problems without adding this one to your list.
So, how do you find these offenders, much less fix them?
That’s what you’ll find out, but only if you click through.
