在此处输入图像描述 上图是我使用 t-SQL 表和视图制作的报告输出的屏幕截图。每列有两个值，第一个是当前数字，然后正斜杠后面是每周的差值。这些数字在我的大多数报告中看起来都不错，但正如您所见，“总计”列似乎具有完全错误的差异值。

该表是使用以下代码创建的

SELECT
   ISNULL(a.[LRPR Biospecimen Consent], 'Missing') AS Consent, 
   CONVERT(varchar, a.Oppong) + ' / ' + CONVERT(varchar, a.Oppong - ISNULL(b.Oppong, 0)) AS Oppong,
   CONVERT(varchar, a.Tousimis) + ' / ' + CONVERT(varchar, a.Tousimis - ISNULL(b.Tousimis, 0)) AS Tousimis,
   CONVERT(varchar, a.Willey) + ' / ' + CONVERT(varchar, a.Willey - ISNULL(b.Willey, 0)) AS Willey,
   CONVERT(varchar, a.Anderson) + ' / ' + CONVERT(varchar, a.Anderson - ISNULL(b.Anderson, 0)) AS Anderson, 
   CONVERT(varchar, a.Bacarra) + ' / ' + CONVERT(varchar, a.Bacarra - ISNULL(b.Bacarra, 0)) AS Bacarra,
   CONVERT(varchar, a.McMahon) + ' / ' + CONVERT(varchar, a.McMahon - ISNULL(b.McMahon, 0)) AS McMahon
FROM
   dbo.vw_RPT_Ourisman_BiospecimenConsentWithProvider_Pivot a 

   LEFT OUTER JOIN dbo.tbl_vw_RPT_Ourisman_BiospecimenConsentWithProvider_Pivot b 
   ON ...

此代码的变体（仅更改路径名已为正斜杠两侧的数字提供了准确的总值。我是 SQL 新手，我似乎无法弄清楚为什么此代码停止工作。

非常感谢任何有用的建议

编辑 下面是用于创建 dbo.vw_RPT_Ourisman_BiospecimenConsentWithProvider_Pivot Total 值的代码。

 With T as ( SELECT     [LRPR Biospecimen Consent], [Oppong, Bridget A] AS Oppong,    [Tousimis, Eleni] AS Tousimis, [Willey, Shawna] AS Willey, [Anderson, Lyndsay] AS Anderson, 
                  [Bacarra, Minna Manalo] AS Bacarra, [McMahon, Ann] AS McMahon
FROM         vw_RPT_Ourisman_BiospecimenConsentWithProvider_List c PIVOT (count([Breast Provider]) FOR [Breast Provider] IN ([Oppong, Bridget A], [Tousimis, Eleni], 
                  [Willey, Shawna], [Anderson, Lyndsay], [Bacarra, Minna Manalo], [McMahon, Ann])) piv
WHERE     [LRPR Biospecimen Consent] IS NOT NULL)
SELECT     *
 FROM         T
UNION ALL
SELECT     'Total', SUM(Oppong), SUM(Tousimis), SUM(Willey), SUM(Anderson), SUM(Bacarra), SUM(McMahon)
FROM         T
