内部联接4个表与组，order by，有条款

Question

我有4个表，我想提取：id，nume，localitate，masina_id，nr_inmatriculare，an_fabricatie，{ {1}}，rafinarie和marca总和(quantity+deliver_quantity)分组total_quantity，按an_fabricatie排序，并添加一些marca。

我不知道如何做到这一点。

我的查询如下，但我认为不正确。

Answer 1

SELECT c.id, c.nume, c.localitate, l.masina_id, i.nr_inmatriculare, i.an_fabricatie, i.rafinarie, m.marca, (SUM(i.quantity) + SUM(l.deliver_quantity)) AS total_quantity
FROM clienti c 
INNER JOIN livrari l ON c.id = l.id 
INNER JOIN incarcari i ON l.incarcare_id = i.livrari_id 
INNER JOIN masini m ON i.id_marca = m.id
GROUP BY i.an_fabricatie, c.id, c.nume,c.localitate,l.masina_id, i.nr_inmatriculare, i.rafinarie, m.marca
HAVING i.quantity > 1000 
ORDER BY m.marca DESC;
