Referencing Objects Owned by the Database Owner

If you omit the owner name and you do not own an object by that name, the SAP ASE server looks for objects of that name owned by the Database Owner.

You must qualify objects owned by the Database Owner only if you own an object of the same name, but you want to use the object owned by the Database Owner. However, you must qualify objects owned by other users with the user’s name, whether or not you own objects of the same name.
