Manipulation with dates

Question

Hi,
The shift timing is from 7am to 3pm.
the actually machine working timings are stored in the machine_timing.
table machine_timing data like
(The table will have the actual machine working time in the shift.)
START_TIME END_TIME
13-06-2012 08:00:00 13-06-2012 13:00:00
13-06-2012 13:30:00 13-06-2012 15:30:00
when the machine is idle (not worked time)that time is stored in the idle_time_table
idle_time_table having data like
( from 7am to 8am the machine is idle for the above shift. so here idle time is one hour from 7am to 8am. and
the lunch break is 13:00 to 13:30 this is also stored in the idle_time_table )
START_TIME END_TIME
13-06-2012 07:00:00 13-06-2012 08:00:00
13-06-2012 13:00:00 13-06-2012 13:30:00
i want code for inserting data to the idle_time_table based on the data which is there in the machine_timing.

Hi user13272730
Here is an example ...
assuming a flag in machine_timing named e.g. inout values for 'I' checked in or 'O' checked out
the time or date is char data type u can create a data base trigger as follow...
CREATE OR REPLACE TRIGGER Emp_ATTENDANCES
AFTER INSERT ON machine_timing.
FOR EACH ROW
BEGIN
IF :NEW.att_inout='I' Then
  INSERT INTO idle_time_table(EMP_ID  , DATE_IN ,  DATE_OUT , TIME_IN  , TIME_OUT )
  VALUES                     (to_number(to_char(:NEW.att_emp_no,99999)) , to_date(:NEW.att_date,'dd/mm/rrrr'), to_date(:NEW.att_date,'dd/mm/rrrr') , to_date(:NEW.att_time,'HH24:MI:SS') , to_date(:NEW.att_time ,'HH24:MI:SS'));
ElsIF :NEW.att_inout='O' Then
  UPDATE idle_time_table 
  SET DATE_OUT  = to_date(:NEW.att_date,'dd/mm/rrrr'),
                TIME_OUT  = To_Date(To_Char(:NEW.ATT_DATE,'DD-MM-YYYY ') || To_Char(:NEW.ATT_TIME,'HH24:MI'),'DD-MM-YYYY HH24 MI');
               WHERE  EMP_ID    = :NEW.att_emp_no
               AND    DATE_OUT  = DATE_IN
               AND    TIME_OUT  = TIME_IN;
End IF;
EXCEPTION
  WHEN OTHERS THEN   RAISE;
END Emp_ATTENDANCES;Hope this helps...
