複選題QUESTION 84 Procedure PROCESS_EMP references the table EMP. Procedure UPDATE_EMP updates rows if table EMP through procedure PROCESS_EMP. There is a remote procedure QUERY_EMP that queries the EMP table through the local procedure PROCESS_EMP. The dependency mode is set to TIMESTAMP in this session. Which two statements are true?
