How do I Use Count Function for different values of the same column in MS-SQL?

Question

For DB StudentInfo and Table Student as follows:

CREATE TABLE Student
(
     ID INT PRIMARY KEY IDENTITY(1,1),
     Name nvarchar(255)
)

and inserting values:

Insert Into Student Values ('Ashok')` 

executing it 3 times, and

Insert Into Student Values ('Achyut')

executing it 2 times and total 5 rows of data are inserted into the table.

I want to display a result counting the result with the name having 'Ashok' & 'Achyut'.

Generally for single values count in a column I use:

 SELECT Count(Name) AS NoOfStudentHavingNameAshok 
 FROM Student
 WHERE Name = 'Ashok'

but how to display the NoOfStudentHavingNameAshok & NoOfStudentHavingNameAchyut what query should I run?

Answer 1

You should include name in the select and group by name .

SELECT name, Count(*) 
From Student
group by name

Answer 2

You can put conditions inside your COUNT() function:

select count(case when Name = 'Ashok' then 'X' end) as NoOfStudentHavingNameAshok,
       count(case when Name = 'Achyut' then 'X' end) as NoOfStudentHavingNameAchyut
  from Student
