The optional list of users to which the logging rules in this BEGIN LOGGING statement apply.
For logging of users authorized privileges by Teradata Database, the user name must be an existing Teradata Database user.
For logging of users authorized privileges in an LDAP directory (that is, AuthorizationSupported=yes in the authentication mechanism):
- If the user is mapped to a permanent database user object in the directory, specify the mapped database user name.
- If the user is not mapped to a permanent database user object in the directory, logging is not supported.
Absence of the BY user_name option specifies all users (those already defined to the system as well as any defined in the future while this logging directive is in effect).
If neither BY user_name nor ON keyword object_name are specified, then the specified action is logged for all users and objects throughout the system.
