You can create an AllUserRights macro to list all the privileges a user has on a specific database. The macro gets information from the DBC.AllRightsV and DBC.AllRolesRightsV views, and spells out the two character privilege code it finds in the AccessRightDesc field of the views.

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.

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

After you create the macro, you can execute it to check access privileges for a particular user with the command:

execute database_name.AllUserRights ('username'); 


  • database_name is the name of the macro, and also identifies database for which the macro checks user privileges
  • username is the name of a permanent database user for which the macro checks privileges
  • The user that executes the macro must have EXECUTE privileges on the database that contains the macro.
