我試圖顯示與許多表相關的表的結果，但我的問題是查詢只返回一個特殊的產品我想返回的產品既是特殊的產品，也是非特殊產品。我的 PHP 查詢是：$query = "SELECT DISTINCT p.product_id, p.price ,sp.date_end, f.percentage AS special_percentage , p.model, pd.name AS title, pd.description AS text, cd.name AS section, p.image, pd.tag, p.date_added AS created "                ."FROM #__mijoshop_product AS p "                ."JOIN #__mijoshop_product_special AS sp ON  p.product_id = sp.product_id "                ."JOIN #__mijoshop_flordeco_product_special_percentage AS f ON sp.product_id = f.product_id "                ."INNER JOIN #__mijoshop_product_description AS pd ON p.product_id = pd.product_id "                ."LEFT JOIN #__mijoshop_product_to_store AS ps ON p.product_id = ps.product_id "                ."LEFT JOIN #__mijoshop_product_to_category AS pc ON p.product_id = pc.product_id "                ."LEFT JOIN #__mijoshop_category_description AS cd ON (pc.category_id = cd.category_id AND cd.language_id = {$language_id}) "                ."LEFT JOIN #__mijoshop_category_to_store AS cs ON (pc.category_id = cs.category_id AND cs.store_id = {$store_id}) "                ."WHERE (LOWER(pd.name) LIKE '%" . $search_text . "%' OR                        LOWER(pd.description) LIKE '%" . $search_text . "%' OR                         LOWER(p.sku) LIKE '%" . $search_text . "%' OR ";                        if( $model ) {                            $query .= "LOWER(p.model) LIKE '%" . $search_text .
