It seems to me you're trying to select the data, and not count it. Maybe a complete drop/create/insert/select cycle of this helps you:

-- drop table if exists supermarket; -- will completely erase the whol
+e table, uncomment only if safe :)

-- create a new table:
create table supermarket (fruit text, color text, supermarket_id integ
+er);

-- insert data:
insert into supermarket (fruit, color, supermarket_id)
                 values ('Orange', 'yellow', 1);
insert into supermarket (fruit, color, supermarket_id)
                 values ('Orange', 'green' , 2);
insert into supermarket (fruit, color, supermarket_id)
                 values ('Orange', 'blue'  , 3);
insert into supermarket (fruit, color, supermarket_id)
                 values ('Grape' , 'black' , 1);
insert into supermarket (fruit, color, supermarket_id)
                values ('Strawberry', 'blue'  , 1);
insert into supermarket (fruit, color, supermarket_id)
                values ('Mellon' , 'red'   , 2);
insert into supermarket (fruit, color, supermarket_id)
                values ('Mellon' , 'green' , 2);
insert into supermarket (fruit, color, supermarket_id)
                values ('Mellon' , 'white' , 1);
insert into supermarket (fruit, color, supermarket_id)
                values ('Banana', 'black' , 1);

-- select data:
select 
    fruit,
    color,
    supermarket_id
from
    supermarket
where 
    supermarket_id in (1,2)
  and     fruit = 'Orange'
order by
    fruit

/* -- resultset:
   "Orange", "yellow", 1
   "Orange", "green" , 2
