如何将行产品转换为列

Question

我有3个表SQL

• 产品[id，name_product]
• customers [id，name_customer]
• data_prodcuts [id，id_product，id_customer，quantity_data]

如何转换PHP和＆amp; MYSQL将表产品名称列添加到列中，并获取所有客户行的组id_product sum（quantity_data）。

谢谢..

我使用SQL

SELECT 
data_prodcuts.id_product, 
sum(data_prodcuts.quantity_data) as total,
data_prodcuts.id_customer,
products.name_product,
customers.name_customer
FROM data_prodcuts
LEFT JOIN products ON products.id = data_prodcuts.id_product
LEFT JOIN customers ON customers.id = data_prodcuts.id_customer
GROUP BY name_product, name_customer
