QryLogTDWMV is the Teradata Dynamic Workload Management view of the main log table DBQLLogTbl.

The nonunique primary index for the underlying table is a combination of the ProcID and the CollectTimeStamp fields. This combination causes each dispatcher to write its DBQL cache entries to a single AMP. This is important for database efficiency.

For information about the possible values for the ExceptionValue column, see "ExceptionValue Column."
