添加导致 GROUP BY 错误的聚合列

Question

我正在向我的查询添加聚合列 min(finumber)。添加此号码后，我希望能够在 ORDER BY 中使用它。当我删除 min(finumber) 时，查询工作正常。当我添加 min(finumber) 时，出现错误：

Column 'soitem.fsono' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.

我的问题是：如何添加 min(finumber) 并将其用于 ORDER BY 我的数据？

SELECT A.fsono,
       MAX(A.Attention) AS Attention,
       MAX(A.Address1) AS Address1,
       MAX(A.Address2) AS Address2,
       A.fcustno,
       A.fcontact,
       A.min_fin

FROM (SELECT soitem.fsono,
             somast.fcustno,
             somast.fcontact,
               min(finumber)as min_fin, 
             CASE
                  WHEN (CONVERT(varchar(MAX), soship.fmstreet)) LIKE 'ATTN%' THEN LEFT(CONVERT(varchar(MAX), soship.fmstreet), CHARINDEX(CHAR(10), CONVERT(varchar(MAX), soship.fmstreet)))
                  ELSE NULL
             END AS Attention,
             CASE WHEN [id] = 2 THEN S.val ELSE NULL END AS Address1,
             CASE WHEN [id] = 3 THEN S.val ELSE NULL END AS Address2
      FROM soitem
           INNER JOIN somast ON soitem.fsono = somast.fsono
           LEFT OUTER JOIN soship ON somast.fsono = soship.fcsono
                                 AND soship.fcenumber = ''
           CROSS APPLY [dbo].[split3](soship.fmstreet, CHAR(13) + CHAR(10)) S
      WHERE (somast.fstatus <> 'Cancelled')
        AND (somast.fsocoord = 'IFP'
          OR somast.fsocoord = '711')
        AND somast.fsono >= '034023') A
GROUP BY A.fsono,
         A.fcustno,
         A.fcontact
 Order by A.fsono, A.min_fin
  ;

错误在这里告诉你问题。

min(finumber) 在您的子查询中，而不是您的主查询中。您的子查询没有 GROUP BY，因此出现错误。您需要使用 OVER 子句。这是伪 SQL，但是：

MIN(finumber) OVER (PARTITION BY {Partition Columns}) AS min_fin

我猜这些列应该是 soitem.fsono, somast.fcustno, somast.fcontact。
