Dear Friend, Both Abhinav's and Prasad's answers are fine. I think you are new to SQL.
Kindly go through about SQL in W3School or msdn. I will help you a lot.

Solution 1

Try select grade, count(*) from stduent group by grade.
Ideally, this is a very simple query and if you read a good book on sql, you should be able to right such a query on your own.

Solution 2

Try this:

SQL

SELECT DISTINCT grade, COUNT(grade) from stduent GROUP BY grade.

Understand how count works, this is really very simple as Abhinav answered.
