    sir this query give me first time in and last time out

    SELECT a.eid, a.date, d.InTime, e.OutTime
    (SELECT DISTINCT eid, date FROM atend) a
    OUTER APPLY (SELECT b.eid, b.Date, MIN(b.Time) InTime FROM atend b WHERE a.eid = b.eid AND a.date = b.date GROUP BY b.eid, b.Date) d
    OUTER APPLY (SELECT c.eid, c.Date, MAX(c.Time) OutTime FROM atend c WHERE a.eid = c.eid AND a.date = c.date GROUP BY c.eid, c.Date) e
    where a.eid='26153 '
    order by a.eid, a.date, d.InTime, e.OutTime

    26153------2013-01-01 00:00:00.000----2013-06-11 09:03:00.000----- 2013-06-11 19:54:00.000

    but actual data is this

    26153-----2013-01-01 00:00:00.000-----2013-06-11 09:03:00.000------I
    26153-----2013-01-01 00:00:00.000-----2013-06-11 12:41:00.000-----O
    26153-----2013-01-01 00:00:00.000-----2013-06-11 13:57:00.000------I
    26153-----2013-01-01 00:00:00.000-----2013-06-11 19:54:00.000-----O

    i want this type of result

    26153------2013-01-01 00:00:00.000----2013-06-11 09:03:00.000----- 2013-06-11 12:41:00.000
    26153------2013-01-01 00:00:00.000----2013-06-11 13:57:00.000----- 2013-06-11 19:54:00.000

    As before, I like to use #temp tables for these things.
    Try this;

    --drop table #temp2
    select eid,[date],[time],[status],
    row_number() OVER (PARTITION by eid,[date],[status] ORDER BY [time]) as rIndex
    into #temp2
    from atend
    select t1.eid,t1.[date],t1.[time] as [intime],t2.[time] as [outtime] from #temp2 t1
    left join #temp2 t2 on t1.eid=t2.eid and t1.[date]=t2.[date] and t2.[status]='O' and t1.rIndex=t2.rIndex
    where t1.eid=26153
    and t1.[status]='I'
    order by t1.[date],t1.[rIndex]

    rIndex is the column alias for the ROW_NUMBER windowing function.Have you copied David's snippet in fully?
