Question

This is what basically my mysql-table looks like:

id  | A  |  B  
-------------
1 | bla  |  1
2 | bla  |  2
3 | bla  |  1
4 | bla  |  1
5 | bla  |  2
6 | bla  |  2
7 | bla  |  1

I wanna count how many rows do have 1 as B value and how many rows do have 2 as B value. Is it possible/does it make sense to do this in one SELECT statement?

Answer 1

use COUNT(*) and GROUP BY , that will give you your result.

SELECT B,count(*) as occurence from myTable group by B;
