[ @newowner=] 'owner '

Is the name of the security account that will be the new owner of the object. owner is sysname, with no default. owner must be a valid database user, server role, Microsoft Windows login, or Windows group with access to the current database.

sp_changeobjectowner removes all existing permissions from the object. You will have to reapply any permissions that you want to keep after running sp_changeobjectowner. Therefore, we recommend that you script out existing permissions before running sp_changeobjectowner. After ownership of the object has been changed, you can use the script to reapply permissions. You must modify the object owner in the permissions script before running. For more information about database scripting, see Documenting and Scripting Databases.

To change the owner of a securable, use ALTER AUTHORIZATION. To change a schema, use ALTER SCHEMA.

Requires membership in the db_owner fixed database role, or membership in both the db_ddladmin fixed database role and the db_securityadmin fixed database role, and also CONTROL permission on the object.

The following example changes the owner of the authors table to Corporate\GeorgeW.

EXEC sp_changeobjectowner 'authors', 'Corporate\GeorgeW';
GO
