A simple UPDATE statement without temporal qualification operates just as an UPDATE on a nontemporal table, completely UPDATING rows that qualify for deletion:

UPDATE employee_vt SET terms='TA07' WHERE ename='Ash';


SELECT * FROM employee_vt;

 eid ename terms   job_start     job_end
---- ----- ----- ----------- -----------
1002 Ash    TA07  2003/01/01  2003/12/31
1005 Alice  TW10  2004/12/01  9999/12/31
1010 Mike   TW07  2015/01/01  2016/12/31
1001 Sania  TW08  2002/01/01  2006/12/31
1004 Fred   PW12  2001/05/01  9999/12/31
1003 SRK    TM02  2004/02/10  2005/02/09
