如何计算每行的总计？

这样，如果我有一个成本列，并且每行中的数据都比我想要在末尾计算其总和，按特定列分组并满足特殊情况。

我试过了：

SELECT
       [SchemeName]
      ,SUM(CAST([SchemeCost] as INT)) as COST
      ,[SchemeHolderName]
      ,[SchemeApprovedBy]
  FROM [WMS_MCP].[dbo].[Schemes]
  Where SchemeHolderName like '%'+ 'Hussain' +'%'
  Group By SchemeCost,SchemeName,SchemeHolderName,SchemeApprovedBy

  UNION ALL

  SELECT
       ''
      ,SUM(CAST([SchemeCost] as INT)) as COST
      ,''
      ,''
  FROM [WMS_MCP].[dbo].[Schemes]
  Where SchemeHolderName like '%'+ 'Hussain' +'%'
  Group By SchemeCost,SchemeName,SchemeHolderName,SchemeApprovedBy

但它没有产生所需的输出，我希望最后一行为空，只有TOTALCOST。

Answer 1

从union

中的第二个select语句中删除Group by子句

    SELECT
   [SchemeName]
  ,SUM(CAST([SchemeCost] as INT)) as COST
  ,[SchemeHolderName]
  ,[SchemeApprovedBy]
  FROM [WMS_MCP].[dbo].[Schemes]
  Where SchemeHolderName like '%'+ 'Hussain' +'%'
  Group By SchemeCost,SchemeName,SchemeHolderName,SchemeApprovedBy

  UNION ALL

  SELECT
   ''
  ,SUM(CAST([SchemeCost] as INT)) as COST
  ,''
  ,''
  FROM [WMS_MCP].[dbo].[Schemes]
  Where SchemeHolderName like '%'+ 'Hussain' +'%'
