SELECT Beer.Beer,
Beer.Brewery,
Beer.Style,
Beer.ABV,
Beer.Hops,
Beer.SRM,
Sum(BeerStock.Quantity) totalQuantity,
CASE WHEN Sum(BeerStock.Quantity) < 0 THEN ''
WHEN Sum(BeerStock.Quantity) BETWEEN 0 AND 999 THEN 'Red'
WHEN Sum(BeerStock.Quantity) BETWEEN 1000 AND 4999 THEN 'Yellow'

men om du verkligen menar det,
SELECT Beer.Beer,
Beer.Brewery,
Beer.Style,
Beer.ABV,
Beer.Hops,
Beer.SRM,
Sum(BeerStock.Quantity) totalQuantity,
CASE WHEN Sum(BeerStock.Quantity) < 0 THEN ''
WHEN Sum(BeerStock.Quantity) BETWEEN 0 AND 999 THEN 'Red'
WHEN Sum(BeerStock.Quantity) BETWEEN 1000 AND 4999 THEN 'Yellow'
WHEN Sum(BeerStock.Quantity) >= 5000 THEN 'GREEN'
END
FROM Beer
INNER JOIN BeerStock
ON Beer.Beer = BeerStock.Beer
-- Where ..other conditions..
En sak till, Du måste också använda GROUP BY
klausul annars kommer du bara att returnera en post även om du har olika poster,
SELECT Beer.Beer,

END
