mysql - 1 つの選択から 2 つの列を更新する方法

Question

これを1つにまとめることはできますか？

UPDATE 1_packages k 
SET 
    rrp = (SELECT 
            SUM(u.quantity * p.rrp) * (sum(p.price_each <> 0 and p.rrp = 0) = 0)
        FROM
            1_packages_plu u
                INNER JOIN
            1_products p ON u.fk_products_id = p.id
        WHERE
            fk_packages_id = k.id)
;

UPDATE 1_packages k 
SET 
    rrp_inc = (SELECT 
            SUM(u.quantity * p.rrp_inc) * (sum(p.price_each <> 0 and p.rrp_inc = 0) = 0)
        FROM
            1_packages_plu u
                INNER JOIN
            1_products p ON u.fk_products_id = p.id
        WHERE
            fk_packages_id = k.id)
;
