这张桌子是我真实桌子的一个简单例子，上面有出口商、产品、标记、托盘、数量等

但我觉得这张桌子最容易知道我的烦恼

我需要在同一个表格中比较两个时期（例如2018年1月和2017年1月），以便区分卖家了解销售结果

有些像这样的

我尝试过这些查询，但是我得到了重复的值，并且卖家没有正确显示

选择*，（Q1-Q2）作为差异
从…起
（选择Id、卖家、产品、标记、金额（数量）作为Q1）
其中日期>='2018-01-01'和日期='2017-01-01'和日期='2018-01-01'和日期='2017-01-01'和日期只需使用条件聚合：
select Id, Seller, Products, Marks,
       sum(case when year(date) = 2017 then quantity end) as quantity_2017,
       sum(case when year(date) = 2018 then quantity end) as quantity_2018,
       (sum(case when year(date) = 2018 then quantity end) -
        sum(case when year(date) = 2017 then quantity end) 
       ) as diff
from realtable
group by Id, Seller, Products, Marks;

最后，它工作得很好
