in an AG setup where you don’t have a readable secondary replica, it can happen that the db owner on a secondary replica is different from owner on the primary replica. In this setup, on a secondary node, sp_helpdb won’t show you the databases that are part of the AG. However, you might use this query to get the db owner information:

SELECT
@@SERVERNAME AS ServerName,
[name] AS dbname,
SUSER_SNAME(owner_sid) AS owner
FROM
sys.databases
WHERE
SUSER_SNAME(owner_sid) != ‘sa’;

You might omit the WHERE clause if you want to get all the databases back.

On a secondary replica you cannot change the database owner because the database cannot be modified. To do this, you need to wait until the secondary replica becomes the primary (e.g. a failover happens).
