i have a table with record given below. What i want is single select query which shows first record min second record avg and third record max value group by mediaid? 

trans_id      playtime       mediaid(F.K.) 
--------      --------       -------------
1              32             2
2              65             2
3              45             3
4              55             4
5              60             3
6              78             2
7              45             4
8              35             3

result should look like 

 playtime       mediaid(F.K.) 
   --------       -------------
    32             2             (Min value)
    58.33          2             (avg value)
    78             2             (Max value)
    35             3             (Min value)
    46.66          3             (avg value)
    60             3             (Max value)
    45             4             (Min value)
    50             4             (avg value)
    55             4             (max value)

this is my real query giving the result but this is not arranged by medtitle 

select  t.medTitle as 'Media',
    min(TIMESTAMPDIFF(SECOND,s.dmtViewStart,s.dmtViewEnd))platime
        from dbedetailing.tblmedia t
        left outer join dbedetailing.tbldoctormediatracktest s on s.dmtMedId = t.medId 
        GROUP BY t.medTitle
        union all
        select  t.medTitle as 'Media',
    avg(TIMESTAMPDIFF(SECOND,s.dmtViewStart,s.dmtViewEnd))platime
        from dbedetailing.tblmedia t
        left outer join dbedetailing.tbldoctormediatracktest s on s.dmtMedId = t.medId 
        GROUP BY t.medTitle
        union all
        select  t.medTitle as 'Media',
    max(TIMESTAMPDIFF(SECOND,s.dmtViewStart,s.dmtViewEnd))platime
        from dbedetailing.tblmedia t
        left outer join dbedetailing.tbldoctormediatracktest s on s.dmtMedId = t.medId 
        GROUP BY t.medTitle ;

this is my real query giving the result but this is not arranged by medtitle

    If you want the values in a single row, you can do this:

    select max(playtime), min(playtime), avg(playtime)
from yourtable
group by mediaid;

    If you want them in separate rows, use a UNION ALL:

    select max(playtime) playtime, mediaid, 'Max' Type
from yourtable
group by mediaid
union all
select min(playtime) playtime, mediaid, 'Min'
from yourtable
group by mediaid
union all
select avg(playtime) playtime, mediaid, 'Avg'
from yourtable
group by mediaid
order by mediaid, playtime;

    Edit #1, using your sample data added:

    select m.medTitle, 
  min(TIMESTAMPDIFF(SECOND, s.dmtViewStart, s.dmtViewEnd)) playtime
from tbldoctormediatracktest s
left join tblmedia m
  on s.MedId = m.MedId
group by m.medTitle
union all

select m.medTitle, 
  avg(TIMESTAMPDIFF(SECOND, s.dmtViewStart, s.dmtViewEnd)) playtime
from tbldoctormediatracktest s
left join tblmedia m
  on s.MedId = m.MedId
group by m.medTitle
union all

select m.medTitle, 
  max(TIMESTAMPDIFF(SECOND, s.dmtViewStart, s.dmtViewEnd)) playtime
from tbldoctormediatracktest s
left join tblmedia m
  on s.MedId = m.MedId
group by m.medTitle
order by medTitle,  playtime
