我从一个表中选择数据,但我还需要使用另一个表的选择子句:

sql&php:

  $condition = "
AND CONCAT_WS('-    ', products_description.products_id, products_attributes.products_attributes_id) = '".$product_number."' 
OR products_description.products_id = '".$product_number."'";

    $show_products_query_string = "
SELECT 
    products_description.products_id AS id,
    products_description.products_name AS product_name, 
    products.products_image AS product_image 
FROM 
    products_description 
    LEFT JOIN products ON products_description.products_id = products.products_id  
    LEFT JOIN warehouse_products ON products_description.products_id = warehouse_products.id" . $filter.$condition;

在这个查询中,我只需要显示我选择的内容:id、name、image_name。

先感谢您!
