MySQL + Query om alle rijen te retourneren met cols die 'actief' zijn in een andere tabel

Ik zal beginnen met te zeggen dat u uw database echt moet normaliseren. Maar dat is een andere vraag. In de tussentijd kunt u deze query gebruiken. Ik heb het maar voor vier ingrediënten getoond, je zou het voor jouw geval moeten uitbreiden tot 15.

SELECT * 
FROM barbot_drinks d
WHERE (ingredient_1_dispenser = '' OR 
       EXISTS(SELECT * FROM barbot_ingredients i WHERE i.active = 1 AND i.dispenser_type = d.ingredient_1_dispenser AND i.ingredient_code = d.ingredient_1_code)) AND
      (ingredient_2_dispenser = '' OR
       EXISTS(SELECT * FROM barbot_ingredients i WHERE i.active = 1 AND i.dispenser_type = d.ingredient_2_dispenser AND i.ingredient_code = d.ingredient_2_code)) AND
      (ingredient_3_dispenser = '' OR
       EXISTS(SELECT * FROM barbot_ingredients i WHERE i.active = 1 AND i.dispenser_type = d.ingredient_3_dispenser AND i.ingredient_code = d.ingredient_3_code)) AND
      (ingredient_4_dispenser = '' OR
       EXISTS(SELECT * FROM barbot_ingredients i WHERE i.active = 1 AND i.dispenser_type = d.ingredient_4_dispenser AND i.ingredient_code = d.ingredient_4_code))

Met uw voorbeeldgegevens levert dit de volgende uitvoer op:

Op basis van enigszins uitgebreide discussies met OP is de vraag als volgt verfijnd. Deze vraag vereist dat dispenser, code en dosering allemaal aanwezig zijn voor elk ingrediënt in de drank. Een SQLFiddle is beschikbaar.
