如何为下面的查询结果插入列

Question

select year, 
 avg(combined_mpg_ft1) as Avg_MPG, 
 avg(tailpipe_co2_in_grams_mile_ft1) as CO2Avg_withoutEV
from fuel$
where fuel_type_1 <> 'Electricity'
group by year
order by year desc

这是我的查询，我想存储 Avg_MPG 和 CO2Avg_withoutEV 的结果以进一步在计算中使用

这是查询结果：

小提琴

with example as
(
select year, 
 avg(combined_mpg_ft1) as Avg_MPG, 
 avg(tailpipe_co2_in_grams_mile_ft1) as CO2Avg_withoutEV
from fuel$
where fuel_type_1 <> 'Electricity'
group by year
order by year desc
)
    UPDATE fuel$  SET fuel$.Avg_MPG=e.Avg_MPG, fuel$.CO2Avg_withoutEV=e.CO2Avg_withoutEV
    FROM fuel$ f
    INNER JOIN Example e on e.year=f.year
