Error - 'The proposed new database owner is already aliased in the database.' occurs when I am trying to use the stored procedure 'sp_changedbowner DYNSA' to change the owner of a SQL database. I looked in DYNGRP for that database but did not find an alias for this user.
If there is an alias for the DYNSA, you may not recognize the alias in DYNGRP. You will need to run the following statement in the SQL Query Analyzer, against the database you were trying to change:
After this, you should be able to run the 'sp_changedbowner DYNSA' stored procedure.
