I have a table with 3 columns: key
, status
and rank
.
status
contains numbers and rank contains t or f.
key is auto numbered and irrelevant here.
my goal is to count how many in each status are t and how many false
for example:
if my data is (key, status, rank)
1 10 f
2 10 t
3 10 t
4 11 t
then result will be : (status, rank, count value)
10 f 1
10 t 2
11 t 1
how do i do that?
