Yes, here is query without one of conditions in WHERE section
SELECT delivery_data.id_product AS id_product, client_tt.id_client_tt
FROM delivery_data JOIN client_tt AS client_tt_tmp ON (client_tt_tmp.id_client_tt =
delivery_data.id_client_tt) JOIN client_tt ON (client_tt_tmp.id_unique = client_tt.id_client_tt)
WHERE delivery_data.delivery_date BETWEEN '2017-09-01' AND '2017-11-30' AND delivery_data.id_ta IN (3911)
GROUP BY client_tt.id_client_tt, delivery_data.id_product
HAVING SUM(delivery_data.amount) > 0
ORDER BY client_tt.id_client_tt
