where database_name is the name of a database in your system, for which the macro checks user privileges. For example, if you create the macro in the DBAdmin database, you identify the macro as DBAdmin.AllUserRights.

This macro returns all privileges granted to a user either directly or through a role. It does not return implicit (ownership) privileges.
