如何用SQL查询是否存在包含特定数量水果的篮子？

  select bucket_id from 对应表  where fruit_id = 2 and count = 2  inner join  select bucket_id from 对应表  where fruit_id = 3 and count = 1  on t1.bucket_id = t2.bucket_id

  select bucket_id from t3,  (    select bucket_id    from 对应表    group by bucket_id    having count(1) = 2  ) t4  where t3.bucket_id = t4.bucket_id
