Try this:
select DISTINCT Name
, REPLACE((select Course AS [data()] from #students s where s.SudentRowId = x.SudentRowId for xml path('')), ' ', ',') AS Course_List
from students x
Hi ,
Thanks for your reply. But if the course is social science, the results which returns is social,science.
StudenRowid Name course
1 paul Math
1 paul English
2 David science
2 David English
3 Tim Math
4 Tom Social science
For Tom it returns social,science which should return social science.
Thanks

Ah, the embedded space, then this is another way to do it and should work. I just liked the elegance of the REPLACE instead of SUBSTRING
Sample output:
select DISTINCT Name
, substring((select ','+Course from students s where s.SudentRowId = x.SudentRowId for xml path('')),2,2000) as Couse_list
from students x
Sample output:
David Science,English
paul Math,English
Tim Social Science
