SQL查询未返回特定结果

Question

我正在尝试创建查询以不包括part_id ='1'的汽车。 这可行，但是由于car_id与多个其他part_id相关联，所以汽车继续显示。

这是我的查询：

SELECT
    distinct car.car_id, 
             part.description
FROM car
JOIN car_parts part on (car.car_id = part.car_id)
WHERE part.part_id <> '1'

我的桌子：car_parts

Car ID | Part ID
   1        1
   1        3
   1        4
   2        2
   2        5
   2        7
   3        1
   3        4
   3        9
   4        1

从查询中返回的唯一car_id是car_id = 2。

Answer 1

SELECT distinct car.car_id, part.description
FROM car
JOIN car_parts part on (car.car_id = part.car_id)
WHERE part.part_id <> '1'
AND car.car_id not in ( select car_id from part where part = 1 )
