麻烦写正确的MySQL查询（COUNT）

Question

我有以下MySQL表：

Person Car  Color 
    ------------------------ 
    1  Audi  Blue 
    2  BMW  Red 
    3  Honda Blue 
    4  Audi  Red 
    5  Audi  Yellow 
    6  Audi  Blue 

我想选择以下：

谁拥有奥迪和他们的颜色的人被发现少每个人都超过3次。

结果应该是4人5 &

我尝试以下查询，但我没有得到期望的结果：

SELECT Person FROM CarTable 
WHERE Car = "Audi" 
GROUP BY Color 
HAVING COUNT(*) < 3 

什么是正确的查询，实现我在做什么？

Answer 1

SELECT Person 
FROM CarTable t1 
JOIN (SELECT color, COUNT(*) c 
     FROM CarTable 
     GROUP BY color 
     HAVING c < 3) t2 
USING (color) 

Answer 2

下面是使用标识第一

select person 
from cars 
where car='Audi' 
     and color in (select color 
        from cars 
        group by color 
        having count(color) < 3);
