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
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

Open in new window

Just make sure you have the last value for the length in SUBSTRING long enough.

Sample output:
David	Science,English
paul	Math,English
Tim	Social Science
