Kombiner data fra to forskellige krydstabeller

Ser næsten ok ud, men du skal også tildele kategori_id'et i venstre ydre joinforbindelse. Ellers får du alle fremhævede elementer af varen:

SELECT i.*, category.name, category_feat_item.item_id AS featured
FROM item AS i
INNER JOIN item_category ON i.id = item_category.item_id
INNER JOIN category ON category.id = item_category.category_id AND category.id =1
LEFT OUTER JOIN category_feat_item ON i.id = category_feat_item.item_id AND category_feat_item.category_id = 1
ORDER BY featured DESC
