I have those MySQL Tables:

products
id

products_content
product_id, lang, product_name, product_content

products_and_categories
product_id, category_id

products_categories
id, parent_id

products_categories_content
category_id, lang, category_name, category_content

products_and_prices
product_id, price_id

products_prices
id

products_prices_content
price_id, lang, description, weight, price, currency

How to select all products from category with id 5 (for example) and all prices for every single product? Is it possible with single query?

Currently to select all products from category, I'm using (CodeIgniter):

    $this->db->select('*')
        ->from('products')
        ->join('products_content', 'products_content.product_id = products.id')
        ->join('products_and_categories', 'products_and_categories.product_id = products.id')
        ->where(array('category_id' => $category_id, 'lang' => $lang));
