Hi,
I need a help.

I have a table where the marks are getting inserted.

+++++++++++++++++++++++++++
RollNo | PaperCode | Marks
+++++++++++++++++++++++++++
A         | 1                |45
A         | 2                |26
A         | 4                |30
B         | 2                |98
B         | 3                |58



I want the result in a table in this way:

+++++++++++++++++++++++++++
RollNo | 1   |2   |3   |4  
+++++++++++++++++++++++++++
A         | 45 |26 | 0  |30
B         |   0  |98 |58 |0


Please help me how can I do like this.

Regards,
Smaranika

Two methods:
IF OBJECT_ID('tempdb..#tmp') IS NOT NULL 
      DROP TABLE #tmp
GO
create table #tmp (
    RollNo          char(1),
    PaperCode       int,
    Marks           int
)
insert into #tmp values 
('A', 1, 45),('A', 2, 26),('A', 4, 30),('B', 2, 98),('B', 3, 58)

-- using CASE statements
select rollno, 
       sum(case PaperCode when 1 then Marks else 0 end) as [1],
       sum(case PaperCode when 2 then Marks else 0 end) as [2],
       sum(case PaperCode when 3 then Marks else 0 end) as [3],
       sum(case PaperCode when 4 then Marks else 0 end) as [4]
from #tmp
group by rollno

-- using PIVOT
select rollno, [1], [2], [3], [4]
from #tmp
pivot (sum(Marks) for Papercode in ([1], [2], [3], [4])) p
