Question

我有表如下結構，

name (type: TEXT) 
price (type: INT) 
color (type: TEXT) 
vehicletype (type: TEXT) eg. SEDAN/SUV 

現在我想檢索（名稱，價格，顏色，vehicletype）如果它的黑色轎車，我已經準備好支付10,000，但如果它的紅色或白色，則不超過8000。對於任何其他顏色，我不會超過7000，除非是SUV，在這種情況下，我的預算高達15,000黑色或高達14,000其他顏色。
我有這個疑問，但它沒有工作，

SELECT name, price, color, vehicletype FROM carrecords WHERE 
(vehicletype = 'SEDAN' AND color = 'black' AND price <= 10000) OR 
(vehicletype = 'SEDAN' AND color IN('red','white') AND price <= 8000) OR 
(vehicletype = 'SEDAN' /* here I tried != "SUV" as well - no luck*/ AND color NOT IN('red','white','black') AND price <= 7000) OR 
(vehicletype = 'SUV' AND color = 'black' AND price <= 15000) OR 
(vehicletype = 'SUV' AND color != 'black' AND price <= 14000) 
ORDER BY price ASC 

是這樣，有什麼解決辦法？

Answer 1

SELECT name, price, color, vehicletype FROM carrecords WHERE 
-- black sedans up to 10k 
(vehicletype = 'SEDAN' AND color = 'black' AND price <= 10000) 
-- red or white sedans up to 8k 
OR (vehicletype = 'SEDAN' AND color IN('red','white') AND price <= 8000) 
-- black SUV up to 15k 
OR (vehicletype = 'SUV' AND color = 'black' AND price <= 15000) 
-- non-black SUV up to 14k 
OR (vehicletype = 'SUV' AND color != 'black' AND price <= 14000) 
-- any other vehicle up to 7k 
OR (price <= 7000) 
ORDER BY price ASC
