But, I don't know why I am getting below error when I ran your way :Server: Msg 209, Level 16, State 1, Line 27
Ambiguous column name 'rollno'.
Try this.
It actually worked fine on my 2008 box but honestly I would expect to see that message too.
select s.*, ISNULL(se.sortorder, 6) as SortOrder
from student s
left join #Sequence se on se.ClassName = s.class
join
(
select rollno, min(ISNULL(sortorder, 6)) as SortOrder
from student s
left join #Sequence se on se.ClassName = s.class
group by rollno
) g on g.rollno = s.rollno and g.SortOrder = ISNULL(se.sortorder, 6)
order by s.rollno, ISNULL(se.sortorder, 6)
