计算商城中2021年每月的GMV
https://www.nowcoder.com/practice/5005cbf5308249eda1fbf666311753bf
select month,round(sum(total_amount)) as GMV from
(select order_id,left(event_time,7) as month,
total_amount from tb_order_overall where status != 2 and year(event_time) = 2021) t
group by month having GMV > 100000 order by GMV ;
这个不难：
1.year=2021
2.ststus!=2
3.GMV=sum(total_amount) cnt没有用
