Let me clear my self.
For example you have two columns in table A : Group and Member.
Now
Group | Member
A | a
A | b
A | c
B | d
B | e
B | f
C | g
C | h

Now when you say top 2 groups than it should return all the data which are belongs to group 'A' and group 'B' right ?

If there are 50 cats, 40 dogs, and 60 elephants, you want to return the top 20 cats, the top 20 dogs, and the top 20 elephants?
Look into ROW_NUMBER().

You almost done.

SQL

SELECT TOP 20 SomeColumn,COUNT(SomeOtherColumn) AS SomeOtherColumn_Count FROM Table_Name
GROUP BY SomeColumn;

FYI TOP[^] & GROUP BY[^] @ www.w3schools.com[^]
