Php Prestashop中的内部联接查询

我想连接两个表，并在prestashop backoffice中显示来自另一个表的数据

目录>产品

我是个新手，我想问一下如何在prestashop上插入或编码

我有两张桌子：

• parts

  ：不是来自

  presta

  它是来自其他网站的自定义表格

---

---

我希望将

InvPartDesc

添加到

Admin

（BO）| Catalog>产品中的产品列表描述中

----------------------------
result
----------------------------
Id | InvPartNo | InvPartDesc
1  | #123      | testprod

像这样的东西应该有用

SELECT 
    ps_products.Id, ps_products.InvPartNo, parts.InvPartDesc, 
FROM ps_products
LEFT JOIN parts ON parts.InvPartNo=ps_products.InvPartNo
GROUP BY ps_products.Id

你的问题是：

$query = Db::getInstance()->executeS(
            'SELECT p.Id, p.InvPartNo, pa.InvPartDesc, 
            FROM '._DB_PREFIX_.'products p 
            INNER JOIN parts pa ON (pa.InvPartNo=p.InvPartNo)'
         );

SELECT 
    ps_products.Id, ps_products.InvPartNo, parts.InvPartDesc, 
FROM ps_products
LEFT JOIN parts ON parts.InvPartNo=ps_products.InvPartNo
GROUP BY ps_products.Id

$query = Db::getInstance()->executeS(
            'SELECT p.Id, p.InvPartNo, pa.InvPartDesc, 
            FROM '._DB_PREFIX_.'products p 
            INNER JOIN parts pa ON (pa.InvPartNo=p.InvPartNo)'
         );
