Get data in range using oracle

Question

Please help me to solve this.

I have a table that contain users check in (checktype = I) and check out (checktype = 0) time everyday, and I would like to get the total amount of check in time per user which occur > 08:00 AM in a specific date range.

I am using the query below, but only handle one day per query not in a range, so I have to loop using javascript to get the amount of delay ( > 08:00 AM) per user for example from 01/06/2012 to 06/06/2012

Please help me to get the amount (count) check in time > 08:00 AM per user (ex: userid 708) from ex:01/06/2012 to 06/06/2012 in a single query.

with tt as 
     ( 
     select TO_DATE('01/06/2012 08:00:00','dd/mm/yyyy hh24:mi:ss') date1 , 
            checktime date2 
     from 
            checkinout 
     where 
            userid = '708' and 
            to_char(checktime,'dd/mm/yyyy') = '01/06/2012' and 
            checktype='I'  -- checktype I is check in
     ) , t2 as 
            ( 
               select numtodsinterval(date2 - date1,'day') dsinterval from tt 
            ) 
            select extract(hour from dsinterval) || ' hours ' || 
                   extract(minute from dsinterval) || ' minutes ' || 
                   round(extract(second from dsinterval)) || ' seconds' late from t2

I assume you wanted to get how many hours late (i.e. after 08:00) the checkins have been done:

with t2 as (
select userid
      ,numtodsinterval(sum(checktime - (trunc(checktime)+8/24)),'day') dsinterval
      ,count(1) cnt
   from checkinout
  where userid='708'
    and checktime > trunc(checktime)+8/24
    and trunc(checktime) between to_date('01/06/2012','DD/MM/YYYY') and to_date('06/06/2012','DD/MM/YYYY')
    and checktype = 'I'
  group by  userid 
)
select extract(hour from dsinterval) || ' hours ' || 
       extract(minute from dsinterval) || ' minutes ' || 
       round(extract(second from dsinterval)) || ' seconds' late 
      ,cnt
   from t2;

See http://sqlfiddle.com/#!4/c4670/11 for my test case.

edit: added column "cnt" to show how many times

Consider the following example on base of this you can write your own logic

WITH tbl AS
     (SELECT SYSDATE dt
        FROM DUAL
      UNION
      SELECT SYSDATE + (1 + (10 / 1440))
        FROM DUAL
      UNION
      SELECT SYSDATE + (2 + (12 / 1440))
        FROM DUAL
      UNION
      SELECT SYSDATE + (3 + (13 / 1440))
        FROM DUAL
      UNION
      SELECT SYSDATE + (6 + (15 / 1440))
        FROM DUAL
      UNION
      SELECT SYSDATE + (8 + (18 / 1440))
        FROM DUAL)
SELECT    EXTRACT (HOUR FROM dsinterval)
       || ' hours '
       || EXTRACT (MINUTE FROM dsinterval)
       || ' minutes '
       || ROUND (EXTRACT (SECOND FROM dsinterval))
       || ' seconds' late
  FROM (SELECT NUMTODSINTERVAL (dt1 - dt2, 'day') dsinterval
          FROM (SELECT TO_DATE (TO_CHAR (dt, 'DD/MM/YYYY') || ' 08:00:00',
                                'DD/MM/YYYY HH24:MI:SS'
                               ) dt1,
                       TO_DATE (TO_CHAR (dt, 'DD/MM/YYYY HH24:MI:SS'),
                                'DD/MM/YYYY HH24:MI:SS'
                               ) dt2
                  FROM tbl
                 WHERE dt BETWEEN SYSDATE + 2 AND SYSDATE + 5))

As per code you can write like

SELECT    EXTRACT (HOUR FROM dsinterval)
       || ' hours '
       || EXTRACT (MINUTE FROM dsinterval)
       || ' minutes '
       || ROUND (EXTRACT (SECOND FROM dsinterval))
       || ' seconds' late
  FROM (SELECT NUMTODSINTERVAL (dt1 - dt2, 'day') dsinterval
          FROM (SELECT TO_DATE (TO_CHAR (checktime , 'DD/MM/YYYY') || ' 08:00:00',
                                'DD/MM/YYYY HH24:MI:SS'
                               ) dt1,
                       TO_DATE (checktime, 'DD/MM/YYYY HH24:MI:SS') dt2
                  FROM checkinout
                 WHERE checktime BETWEEN start_date AND end_date 
                   AND checktype='I'))
