sql-server - 对 'UNION' 的查询执行 'ORDER BY'

Question

我在Union all 中遇到语法错误。我知道我做不到这一点。但是有人可以帮我吗？

SELECT
ID, 
date1, 
date2 row_number() OVER (PARTITION BY ID ORDER BY date1 DESC )  as RN1, 
1 as Range
FROM 
(
SELECT ID,date1,
rn = row_number() OVER (PARTITION BY ID ORDER BY date1 )
FROM listing_History   (nolock)
WHERE [date1] <=   CONVERT(DATE,DATEADD(MONTH, -6, GETDATE()))  AND 
ID in (SELECT txt FROM [dbo].[fn_ListToTable](@listStr, ',')) 
)  AS A ORDER BY date1 DESC, date2 DESC

UNION ALL 

SELECT
ID, 
Date1, 
date2 row_number() OVER (PARTITION BY ID ORDER BY date1 DESC )  as RN1, 
1 as Range
FROM 
(
SELECT 
ID,
date1,
rn = row_number() OVER (PARTITION BY ID ORDER BY date1 )
FROM listing_History   (nolock)
WHERE [status_date] <=   CONVERT(DATE,DATEADD(MONTH, -3, GETDATE()) -1)
AND 
ID in (SELECT txt FROM [dbo].[fn_ListToTable](@listStr, ',')) 
) AS A ORDER BY date1 DESC,date2 desc

删除除最后一个之外的每个 UNION 中的所有 ORDER BY，并确保您在 ORDER BY 中引用的列名称对应于第一个SELECT。
