SQL - bagaimana cara PILIH beberapa tabel dan GABUNG beberapa baris dari kolom yang sama?

Anda dapat bergabung ke tabel yang sama beberapa kali, Anda hanya perlu memberikan alias yang berbeda

SELECT painting.id, 
       painting.order, 
       painting_en.url, 
       `group`.en AS `group`, 
       TYPE.en AS type, 
       location.en AS location
FROM   painting 
       LEFT JOIN painting_en 
       USING (id) 
       LEFT JOIN id_portfolio `group` 
         ON `group`.id = painting.id_group 
       LEFT JOIN id_portfolio TYPE 
         ON TYPE.id = painting.id_type 
       LEFT JOIN id_portfolio location 
         ON location.id = painting.id_location 
WHERE  painting_en.url = '2011-name3' 
LIMIT  1
