Prerequisites

You have generated the demo data for the SQL Tutorial.

Log on to the demo database instance DEMODB as user MONA.

Examples

You can use the system table ROLES to determine the following database information, among other things:

●     All roles for which it is necessary to enter a password to activate them

SELECT owner, role
  FROM DOMAIN.ROLES
    WHERE password_required = 'YES'

●     Role of the current user that is automatically activated when a database session is opened

SELECT role
  FROM DOMAIN.ROLES
    WHERE defaultrole = 'YES'

All roles that are active in the current database session: see SESSION_ROLES
