I have deployed a ssrs report in report server. when I'm trying to run that report in report server, it displays nothing. but it fetches the appropriate result in 'Preview'. I am new to ssrs reports.
My query :
if @department is not null and @Course is not null select
student_name,average from student where student_id=@studentid
else if @department is not null and @Course is null select
student_name,average from student where student_id=@studentid and
department_name=@department
@department , @course are optional user inputs
@student_id is mandatory user input
