Trigger kan de tabel niet lezen (Selecteer KPI_FREQ_TIME_UNIT FROM KPI_DEFINITION), die verandert... u kunt de waarde op deze manier openen::new.KPI_FREQ_TIME_UNIT.Meer info:http://www.dba-oracle.com/t_avoiding_mutating_table_error.htm
In andere gevallen kunt u het proberen in autonome transactie :
create or replace TRIGGER RATOR_MONITORING_CONFIGURATION."TRG_TRK_KPI_DEFINITION"
AFTER UPDATE ON RATOR_MONITORING_CONFIGURATION.KPI_DEFINITION FOR EACH ROW
DECLARE
PRAGMA AUTONOMOUS_TRANSACTION;
BEGIN
-- ...
COMMIT; -- don't forget it!!!
END;
