in reply to (OT) Exclusion selection on DBI

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 */
