We're recently purchased some new software, which requires its own SQL Server database. Working with the vendor they also needed to have a new SQL account created which would be a part of the db_owner database role membership. Creating new SQL accounts isn't something we do often (I cannot remember when I last created a new SQL account), so I made a mistake when I set the new user up. Here's what happened:
First, I created the new database. After setting it up, assigning the .mdf and .ldf files to their appropriate places, I then created the new SQL account, and in the property page for creating the new user, I checked db_owner under the "Schemas owned by this user", rather than "Database role membership".
Later I realized my mistake, but I'm not sure how to fix it. First of all, what account normally has ownership of the db_owner schema? I would assume it would be the sa account, especially for a new database like this one, but I want to ask anyway.
Second, how do I reassign the db_owner schema from this new SQL account to the account it should really be owned by?

Usually, the fixed database roles are owned by dbo. Check the properties of some of the other roles in the database e.g. db_securityadmin, db_ddladmin, etc. You can change the owner of a role by opening the properties of the role in object browser and either typing in the new owner or clicking on the elipse and choosing the new owner from the list.

The default owner of the db_owner Schema is dbo. Use this to change it back.

USE [DatabaseName]

GO

ALTER AUTHORIZATION ON SCHEMA::[db_owner] TO [dbo]

GO

Hi there. I have a user I could not delete because they were a db_owner. I used the following alter statement and after that was able to delete them. The statement was as follows:

ALTER AUTHORIZATION ON SCHEMA::db_owner TO dbo;

My question is should it be the following below:

ALTER AUTHORIZATION ON SCHEMA::db_owner TO dbo_owner;

Thanks for your help

You are correct. It should be dbo not db_owner. I'll update my earlier post.

Thanks!
