MSAccess SQL查询-使用多个表合并所有表-重复字段

我试着从三个查询中提取总数，分别是

qryBOM

、

qryLabour

和

qryLaser

，并将它们列在一行

我已经创建了一个

qryTotals

过滤器，下面是我的代码：

SELECT
  Sum(tempTotalLabour) AS TotalLabour,
  Sum(tempTotalCost) AS TotalCost,
  Sum(tempTotalLaser) AS TotalLaser,
  [TotalLabour] + [TotalCost] + [TotalLaser] AS ProductCost

FROM
      (

    SELECT
      Sum([qryLabour].[Labour Mins]) AS tempTotalLabour,
      Sum([qryLabour].[$ Cost]) AS tempTotalCost,
      Sum([qryLabour].[Laser Mins]) AS tempTotalLabour
    FROM
      qryLabour

    union all

    SELECT
      Sum([qryBOM].[Labour Mins]) AS tempTotalLabour,
      Sum([qryBOM].[$ Cost]) AS tempTotalCost,
      Sum([qryBOM].[Laser Mins]) AS tempTotaMaterial
    FROM
      qryBOM

    union all

    SELECT
      Sum([qryLaser].[Labour Mins]) AS tempTotalLabour,
      Sum([qryLaser].[$ Cost]) AS tempTotalCost,
      Sum([qryLaser].[Laser Mins]) AS tempTotalLaser
    FROM
      qryLaser

  ) AS TotalTable;

但是我得到了一个错误

重复的输出别名-'testotallabour'

。请有人帮我解决哪里出了问题，这样我就可以解决这个问题，为将来学习

干杯

您使用了两次

诱惑Totalabour

我做了一次，如下所示

SELECT
  Sum(tempTotalLabour) AS TotalLabour,
  Sum(tempTotalCost) AS TotalCost,
  Sum(tempTotalLaser) AS TotalLaser,
 Sum(tempTotalLabour) + Sum(tempTotalCost) + Sum(tempTotalLaser) AS ProductCost

FROM
      (

    SELECT
      Sum([qryLabour].[Labour Mins]) AS tempTotalLabour,
      Sum([qryLabour].[$ Cost]) AS tempTotalCost,
      Sum([qryLabour].[Laser Mins]) as tempTotalLaser

    FROM
      qryLabour

    union all

    SELECT
      Sum([qryBOM].[Labour Mins]) AS tempTotalLabour,
      Sum([qryBOM].[$ Cost]) AS tempTotalCost,
      Sum([qryBOM].[Laser Mins]) AS tempTotalLaser
    FROM
      qryBOM

    union all

    SELECT
      Sum([qryLaser].[Labour Mins]) AS tempTotalLabour,
      Sum([qryLaser].[$ Cost]) AS tempTotalCost,
      Sum([qryLaser].[Laser Mins]) AS tempTotalLaser
    FROM
      qryLaser

  ) AS TotalTable;

这不能是您正在运行以获取该错误消息的SQL。该错误指的是

templaboroutput

，它在查询中没有位置。请包含生成实际错误消息的实际查询。很抱歉，您是对的，我输入错误。你必须学会校对代码。除了明显的打字错误和拼写错误之外，这里没有任何问题。抱歉，我使用的是Access查询编辑器，所有内容都在一行中，我只是以上述方式进行格式化，以便于堆栈用户阅读-我应该加倍检查，因为我现在可以发现问题
