MYSQL查找每年至少订购过一次针对该项目提交反馈的客户

Question

我想使用MySQL进行查询，以查找过去3年（2016年至2019年）每年至少订购或下载一次的客户。但是，他们必须对订购或下载的那些物品留下反馈。

因此，我必须使用以下表格：反馈，FAV（代表免费的年度视频）和下载，以及Contact（包含所有用户信息）

SELECT c.id, c.FirstName, c.LastName
FROM contact c

JOIN download_counts dl
    on c.Id = dl.ContactId
JOIN freeannualvideo f
    on c.Id = f.ContactId
INNER JOIN (select fb.ItemId
                            from feedback fb
                            group by fb.ItemId) FBExistFAV
                            ON FBExistFAV.ItemId = f.ItemId
INNER JOIN (select fb.ItemId
                            from feedback fb
                            group by fb.ItemId) FBExistDL
                            ON FBExistDL.ItemId = dl.ItemId
WHERE  
    EXISTS (select 1 from download_counts dl where c.id = dl.ContactId and dl.DateAdded between '2016-06-30' and '2017-06-30')   
        AND EXISTS (select 1 from download_counts dl where c.id = dl.ContactId and dl.DateAdded between '2017-07-01' and '2018-06-30')   
        AND EXISTS (select 1 from download_counts dl where c.id = dl.ContactId and dl.DateAdded between '2018-07-01' and '2019-04-27') 
OR 

        (EXISTS (select 1 from freeannualvideo f where c.id = f.ContactId and f.DateAdded between '2016-06-30' and '2017-06-30')
        AND EXISTS (select 1 from freeannualvideo f where c.id = f.ContactId and f.DateAdded between '2017-07-01' and '2018-06-30') 
        AND EXISTS (select 1 from freeannualvideo f where c.id = f.ContactId and f.DateAdded between '2018-07-01' and '2019-04-27'))


GROUP BY c.Id;

因此，联系人必须在2017、2018和2019 PLUS至少拥有一个DL或FAV，他们每年需要为其中一个DL或FAV提供反馈

很好的例子：（应该拉）
约翰·史密斯
2017年有DL或FAV且左反馈
2018年有DL或FAV且有左反馈
2019年有DL或FAV且有左反馈

错误的例子：（不应该被拉）
杰克·约翰逊
2017年有DL或FAV且左反馈
2018年出现DL或FAV并留下否反馈
2019年有DL或FAV且有左反馈
