Такая проблема:
Таблицы:
CREATE TABLE products (
  products_id int NOT NULL auto_increment,
...
  products_image varchar(64),
  products_price decimal(15,4) NOT NULL,
  PRIMARY KEY (products_id),
  KEY idx_products_date_added (products_date_added)
);

CREATE TABLE products_description (
  products_id int NOT NULL auto_increment,
  language_id int NOT NULL default '1',
  products_name varchar(64) NOT NULL default '',
...
  PRIMARY KEY  (products_id,language_id),
  KEY products_name (products_name)
);

CREATE TABLE products_to_categories (
  products_id int NOT NULL,
  categories_id int NOT NULL,
  PRIMARY KEY (products_id,categories_id)
);

CREATE TABLE categories (
  categories_id int NOT NULL auto_increment,
  parent_id int DEFAULT '0' NOT NULL,
...
  PRIMARY KEY (categories_id),
  KEY idx_categories_parent_id (parent_id)
);

CREATE TABLE categories_description (
  categories_id int DEFAULT '0' NOT NULL,
  language_id int DEFAULT '1' NOT NULL,
  categories_name varchar(32) NOT NULL,
...
  PRIMARY KEY (categories_id, language_id),
  KEY idx_categories_name (categories_name)
);

Необходимо сделать выборку из этих таблиц для каждого продукта. С этим проблем нету:
