Question

我可以在哪里找到Prestashop SQL查询，它们显示按顺序购买的产品。

像这样：

我正在创建一个自定义页面，在表格中显示100个订单。如果点击订单，它会显示订购的产品。我做了一个SQL查询：

SELECT product_id, product_reference AS kood,product_name AS nimetus,product_quantity AS nr, pl.link_rewrite,psa.quantity as kogukogus,group_concat(ps.product_supplier_reference) as supp_ref, p.location AS asukoht,
         CONCAT(c.link_rewrite,'/',p.id_product,'-',pl.link_rewrite,'.html') link
        FROM ps_order_detail o
        LEFT JOIN ps_product_lang pl on o.product_id = pl.id_product
        LEFT JOIN ps_product p on p.id_product = pl.id_product
        LEFT JOIN ps_stock_available psa on p.id_product = psa.id_product
        LEFT JOIN ps_category_lang c on c.id_category = p.id_category_default
        LEFT JOIN ps_product_supplier ps on p.id_product = ps.id_product
        WHERE pl.id_lang=2 AND c.id_lang=2 AND id_order= '".$q."'
        GROUP BY product_id, kood,nimetus,nr,pl.link_rewrite, kogukogus,asukoht, link

但是当产品具有属性时，它会复制产品。

在这种情况下，iButton有两种颜色黑色和红色（属性）。按此顺序，只有一个黑色的iButton以20的数量购买，但它显示了三行。

我试图解决这个问题，但是我的sql查询出现了另一个问题，即当它没有属性时它就不会显示任何内容。

SELECT product_id, product_reference AS kood,product_name AS nimetus,product_quantity AS nr, pl.link_rewrite,psa.quantity as kogukogus,group_concat(ps.product_supplier_reference) as supp_ref, p.location AS asukoht,
         CONCAT(c.link_rewrite,'/',p.id_product,'-',pl.link_rewrite,'.html') link
        FROM ps_order_detail o
        JOIN ps_product_lang pl on o.product_id = pl.id_product
        JOIN ps_product p on p.id_product = pl.id_product
        JOIN ps_stock_available psa on p.id_product = psa.id_product
        JOIN ps_category_lang c on c.id_category = p.id_category_default
        JOIN ps_product_supplier ps on p.id_product = ps.id_product
        LEFT JOIN ps_product_attribute pa on p.id_product=pa.id_product
        WHERE pl.id_lang=2 AND pa.id_product_attribute = psa.id_product_attribute AND pa.id_product_attribute =o.product_attribute_id  AND c.id_lang=2 AND id_order= '".$q."'
        GROUP BY product_id, kood,nimetus,nr,pl.link_rewrite, kogukogus,asukoht, link

如何解决此问题？

Answer 1

我认为您必须将WHERE个条件中的2个移至JOIN条件。可能只移动LEFT JOIN上的条件就足够了。这应该是结果：

SELECT DISTINCT product_id, product_reference AS kood,product_name AS nimetus,product_quantity AS nr, pl.link_rewrite,psa.quantity as kogukogus,group_concat(ps.product_supplier_reference) as supp_ref, p.location AS asukoht,
         CONCAT(c.link_rewrite,'/',p.id_product,'-',pl.link_rewrite,'.html') link
        FROM ps_order_detail o 
        JOIN ps_product_lang pl on o.product_id = pl.id_product
        JOIN ps_product p on p.id_product = pl.id_product
        JOIN ps_stock_available psa on p.id_product = psa.id_product
        JOIN ps_category_lang c on c.id_category = p.id_category_default
        JOIN ps_product_supplier ps on p.id_product = ps.id_product
        LEFT JOIN ps_product_attribute pa on p.id_product=pa.id_product
                   AND psa.id_product_attribute = pa.id_product_attribute 

        WHERE pl.id_lang=2 AND c.id_lang=2 AND id_order= '".$q."'

Answer 2

如果您对结果的特定产品属性不感兴趣，请在查询中使用SELECT DISTINCT而不是简单的SELECT

Answer 3

感谢您的回答，这真的很愚蠢但是当从组中删除kogukogus并且结果如下：

SELECT product_id, product_reference AS kood,product_name AS nimetus,product_quantity AS nr, pl.link_rewrite,psa.quantity as kogukogus,group_concat(ps.product_supplier_reference) as supp_ref, p.location AS asukoht,
         CONCAT(c.link_rewrite,'/',p.id_product,'-',pl.link_rewrite,'.html') link
        FROM ps_order_detail o
        LEFT JOIN ps_product_lang pl on o.product_id = pl.id_product
        LEFT JOIN ps_product p on p.id_product = pl.id_product
        LEFT JOIN ps_stock_available psa on p.id_product = psa.id_product
        LEFT JOIN ps_category_lang c on c.id_category = p.id_category_default
        LEFT JOIN ps_product_supplier ps on p.id_product = ps.id_product
        WHERE pl.id_lang=2 AND c.id_lang=2 AND id_order= '".$q."'
        GROUP BY product_id, kood,nimetus,nr,pl.link_rewrite,asukoht, link

我以某种方式工作了。谢谢你@ kiks73，你的代码没有用，但是当我试图将你的代码添加到你的代码时，我意识到问题出在group by上。所以赏金归于你，因为没有人回答任何严肃的事情
