How to count rows that have the same values in two columns (SQL)?

Question

I am sure there must be a relatively straightforward way to do this, but it is escaping me at the moment. Suppose I have a SQL table like this:

+-----+-----         


        

Answer 1

This should do it:

SELECT A, B, COUNT(*) 
FROM TableName
GROUP BY A, B;

Answer 2

SELECT A, B, COUNT(*) FROM MyTable GROUP BY A, B

Answer 3

SELECT A,B,COUNT(*)
FROM table
GROUP BY A,B

Answer 4

SELECT A,B,COUNT(*)
FROM the-table
GROUP BY A,B

Answer 5

TRY:

SELECT
    A, B , COUNT(*)
    FROM YourTable
    GROUP BY A, B

Answer 6

This could be the answer:

SELECT a, b, COUNT(*) 
FROM <your table name here> 
GROUP BY a,b 
ORDER BY 3 DESC;
