Answer 1

You can use LEFT JOIN like,
SELECT p.id,p.pname,g.price,g.discount,g.product_qty FROM
grocery_product as p
LEFT JOIN grocery_attribute as g
ON p.id = g.product_id
WHERE p.id=2
Now you can loop for attributes and show different price, discount, and product_qty for a single product.
// Let $products is multidimensional array
if(!empty($products) && isset($products[0]['pname'])){
echo '<h1>'.$products[0]['pname'].'</h1>';
foreach($products as $product){
echo 'Price:'.$product['price']."\n";
echo 'Discount:'.$product['discount']."\n";
echo 'Product Quantity:'.$product['product_qty']."\n";
}
}
