クエリ実行が遅い

Question

私は次のクエリを実行しています。これはGroup Byによると思います。誰でもこのクエリを修正してGroupByを使わずにクエリを実行できますが、出力結果は同じでなければなりません。

SELECT order_id, 
     sum(item_total)item_total, 
     sum(discount)discount, 
     sum(shipping_amount)shipping_amount, 
     sum(tax_total)tax_total, 
     sum(grand_total)grand_total, 
     order_status, 
     order_date, 
     store_label, 
     promotion_key, 
     store_identifier, 
     ship_party_name, 
     ship_address1, 
     ship_address2, 
     ship_city, 
     ship_zip, 
     ship_state, 
     ship_to_phone, 
     ship_type, 
     bill_party_name, 
     bill_address1, 
     bill_address2, 
     bill_city, 
     bill_state, 
     bill_zip, 
     bill_to_phone, 
     bill_to_email, 
     card_brand, 
     credit_card_number 
FROM apps.SCHL_ORDER_DETAILS_V 
WHERE UCN=? 
    AND order_id=? 
GROUP BY order_id, 
     order_status, 
     order_date, 
     store_label, 
     promotion_key, 
     store_identifier, 
     bill_party_name, 
     bill_address1, 
     bill_address2, 
     bill_city, 
     bill_state, 
     bill_zip, 
     bill_to_phone, 
     bill_to_email, 
     card_brand, 
     credit_card_number, 
     ship_party_name, 
     ship_address1, 
     ship_address2, 
     ship_city, 
     ship_zip, 
     ship_state, 
     ship_to_phone, 
     ship_type, 
     store_label

私はそれができますかはわからない - しかし、あなたはuが集約を必要とするならば、uは、私たちが必要とするすべての最初の...私は考えてそれを避けることはできませんサブクエリ
