Teradata Vantage generates a log entry only if a logging rule is present and active for the object, action, or user for which it performs a privilege check. When the database finds one or more active rules, it logs the associated privilege checks in the DBC.AccLogTbl table for each user request that matches a rule.

A log entry does not necessarily indicate that the statement executed, instead, it indicates that the system checked on the privileges required to execute the statement. The corresponding row in DBC.AccLogTbl shows an entry of either “denied” or “granted.”

Log entries may contain one or two user names:
  • The log entry always shows the logon username for the user that initiates the session.
  • The log entry may show a second name for some entries. For example, if a user submits an EXECUTE statement for a macro, the system checks the database privileges of the logon username for the EXECUTE statement, and also checks the database privileges required of the macro owner for individual statements within the macro. The log entry lists both the logon user and the macro owner.
