Sql server 如何使用ORDERBY case when子句对列表进行排序（SQL Server）

我试图根据

month

和

id

对列表进行排序，这样，如果是某个

month

和

id

将在顶部排序，否则将在下面排序

我希望使用order by with case when子句，但我得到以下错误：

ORDER BY items must appear in the select list if SELECT DISTINCT is specified.

查询

declare @month int = month(getDate())

select distinct 
[description],
[item],
[meta]
order by case
when @month = 1 and item = 'A00' then 12
when @month = 2 and item = 'B00' then 11
when @month = 3 and item = 'C00' then 10
when @month = 4 and item = 'D00' then 9
when @month = 5 and item = 'E00' then 8
when @month = 6 and item = 'F00' then 7
when @month = 7 and item = 'G00' then 6
when @month = 8 and item = 'H00' then 5
when @month = 9 and item = 'I00' then 4
when @month = 10 and item = 'J00' then 3
when @month = 11 and item = 'K00' then 2
when @month = 12 and item = 'L00' then 1
else 0 end desc

如何根据两个参数对它们进行排序？

尝试将DISTICNT替换为GROUP BY
