Get frequency of a column in SQL Server

Question

I have a column with values like 1,1,2,1,... and I would want to get the frequency of 1 and 2, I did

SELECT count(column)
FROM table
WHERE column = 1;

SELECT count(column)
FROM table
WHERE column = 2;

But, could I take the frequency with a more direct way?

Answer 1

Use aggregate functions

 Select column, count(*)
 From   table
 Group By column

This will return one row that contains the count, for each distinct value in column

Answer 2

One row each value:

select column 'value', count (column) 'Frequency'
from table
group by column

if only 2 values this give you both results in one row

select sum(case when column=1 then 1 else 0 end) as '1 Frequency',
        sum(case when column=2 then 1 else 0 end) as '2 Frequency'
from table
