Thnx for your reply..

I tried this

SELECT E.EXAMNAME,C.COURSENAME FROM EXAMS E
INNER JOIN COURSES C
ON CONVERT(VARCHAR,C.CourseID)=E.CourseID
WHERE E.CourseID=1

But i am getting this error

Msg 245, Level 16, State 1, Line 2
Conversion failed when converting the varchar value '3,2' to data type int.

SELECT E.EXAMNAME,C.COURSENAME FROM EXAMS E
INNER JOIN COURSES C
ON ','+E.COURSEID+',' like '%,'+cast(C.COURSEID as varchar(10))+',%'
WHERE ','+E.COURSEID+',' like ',1,'
