The BEGIN QUERY LOGGING and REPLACE QUERY LOGGING statements give the administrator flexibility in determining what SQL requests are to be logged based on the user ID and/or account string. It also determines what level of detail is captured for a selected request. DBQL does not, however, allow for rules to be selective based on request type or object accessed. In other words, DBQL logs all request types and target database objects. Therefore, the user ID and account string serve as the primary selection criteria.
If a Teradata dynamic workload management software exception occurs, the Teradata dynamic workload management software causes rows to be written to the DBQLSqlTbl.
For information on this type of an exception, see Application Programming Reference or use Teradata Viewpoint.
