Hi.... I want to know what syntax should i used for UPDATE or ON DUPLICATE KEY. Because now, I only have syntax for insert query.,I want to add syntax for update or DUPLICATE key. here is my code: Code: <?php include 'config.php'; $currentEmpID = $_SESSION['empID']; $DATE1 = $_GET['Regfirstinput']; $DATE2 = $_GET['Regsecondinput']; $smarty->assign('DATE1', $DATE1); $smarty->assign('DATE2', $DATE2); $result = mysql_query("INSERT INTO payroll.reg_att(EMP_NO, DATE_DTR, LOGIN, LOGOUT, TotalHours) SELECT EMP_NO, DATE(LOGIN), LOGIN, LOGOUT, TIMEDIFF(LOGOUT, LOGIN) FROM attendance.employee_attendance") or die(mysql_error()); $result = mysql_query("UPDATE payroll.reg_att SET Rendered = case when time_to_sec(time(TotalHours)) <= time_to_sec('03:00:00') then sec_to_time(time_to_sec('00:00:00')) when time_to_sec(time(LOGIN)) BETWEEN time_to_sec('20:35:00') AND time_to_sec('21:35:00') AND time_to_sec(time(LOGOUT)) BETWEEN time_to_sec('05:35:00') AND time_to_sec('06:35:00') then sec_to_time(time_to_sec('08:00:00')) when time_to_sec(time(LOGIN)) BETWEEN time_to_sec('04:35:00') AND time_to_sec('05:35:00') AND time_to_sec(time(LOGOUT)) BETWEEN time_to_sec('13:35:00') AND time_to_sec('14:35:00') then sec_to_time(time_to_sec('08:00:00')) when time_to_sec(time(LOGIN)) BETWEEN time_to_sec('12:35:00') AND time_to_sec('13:35:00') AND time_to_sec(time(LOGOUT)) BETWEEN time_to_sec('21:35:00') AND time_to_sec('22:35:00') then sec_to_time(time_to_sec('08:00:00')) when time_to_sec(time(LOGIN)) BETWEEN time_to_sec('06:00:00') AND time_to_sec('07:00:00') AND time_to_sec(time(LOGOUT)) BETWEEN time_to_sec('16:00:00') AND time_to_sec('16:59:00') then sec_to_time(time_to_sec('08:00:00')) when time_to_sec(time(LOGIN)) BETWEEN time_to_sec('07:01:00') AND time_to_sec('08:00:00') AND time_to_sec(time(LOGOUT)) BETWEEN time_to_sec('17:00:00') AND time_to_sec('17:59:00') then sec_to_time(time_to_sec('08:00:00')) when time_to_sec(time(LOGIN)) BETWEEN time_to_sec('07:01:00') AND time_to_sec('08:00:00') AND time_to_sec(time(LOGOUT)) BETWEEN time_to_sec('18:00:00') AND time_to_sec('18:59:00') then sec_to_time(time_to_sec('08:00:00')) when time_to_sec(time(LOGIN)) BETWEEN time_to_sec('21:35:00') AND time_to_sec('22:35:00') AND time_to_sec(time(LOGOUT)) BETWEEN time_to_sec('05:35:00') AND time_to_sec('07:35:00') then sec_to_time(time_to_sec(concat(substr(LOGIN, 1,10), ' ' , '08:00:00')) -
