Question

我有以下查询：

WITH Calender AS 
(
    SELECT @FromDate AS CalanderDate
    UNION ALL
    SELECT CalanderDate + 1 FROM Calender
    WHERE CalanderDate + 1 <= @ToDate
)
INSERT INTO #C
SELECT [Date] = CONVERT(VARCHAR(10),CalanderDate,25)
     , case [dbo].[CalculateNumericWeekCode] (4, CalanderDate)
         when 1 then 'A'
         when 2 then 'B'
         when 3 then 'C'
         when 4 then 'D'
         end
        , TT.Name
    , 'Green'
    , 'Green'
    , FREQ.pageid
    ,''
FROM Calender,
     TransportType AS TT INNER JOIN #F AS FREQ ON FREQ.TransportTypeID = TT.TransportTypeId
     WHERE TT.TransportTypeID = @TransportTypeID
UNION
SELECT [Date] = CONVERT(VARCHAR(10),CalanderDate,25)
     , case [dbo].[CalculateNumericWeekCode] (4, CalanderDate)
         when 1 then 'A'
         when 2 then 'B'
         when 3 then 'C'
         when 4 then 'D'
         end
     , TT.Name
    , Case INC.incidentstatusid
       when 6 -- Approved
          then 'Blue'
       else
          ''
      END
    , 'Green'
    , FREQ.pageid
    ,''
FROM Calender,
     TransportType AS TT INNER JOIN #F AS FREQ ON FREQ.TransportTypeID = TT.TransportTypeId
     INNER JOIN [Incident] AS INC on FREQ.Task = INC.Task AND FREQ.Contract = INC.Contract AND CalanderDate = INC.[EstimatedCompletionStamp]
     INNER JOIN [IncidentStatus] AS INCSTAT ON INCSTAT.IncidentStatusID = INC.IncidentStatusID
     INNER JOIN [IncidentSubType] AS INCSTYP ON INCSTYP.incidentsubtypeid = INC.IncidentSubTypeID and INC.IncidentSubTypeID in (20,21,22,23) and INC.TransportTypeId = TT.TransportTypeID

我的#C-table声明如下：

CREATE TABLE #C
(  
  DateOfTransport DateTime not null,
  WeekCode varchar(1) NOT NULL,
  [TransportType] varchar(25) NULL,
  [CSDColor] varchar(10) not null,
  [WWWColor] varchar(10) not null,
  [PageID] int not null,
  [ToolTip] varchar(250) null
)

现在，当我运行查询时，收到消息：无效的列名'CalanderDate'。

当我删除UNION它工作正常。但我确实需要不同表之间的联合。

任何人都可以帮助我吗？

我想我发现了这个问题：

正如我所怀疑的，它是由你的混合风格引起的：

此on子句无效on FREQ.Task = INC.Task AND FREQ.Contract = INC.Contract AND CalanderDate = INC.[EstimatedCompletionStamp]，因为您在calander上使用隐式联接。

我认为这应该有效：

SELECT [Date] = CONVERT(VARCHAR(10),CalanderDate,25)
     , case [dbo].[CalculateNumericWeekCode] (4, CalanderDate)
         when 1 then 'A'
         when 2 then 'B'
         when 3 then 'C'
         when 4 then 'D'
         end
     , TT.Name
    , Case INC.incidentstatusid
       when 6 -- Approved
          then 'Blue'
       else
          ''
      END
    , 'Green'
    , FREQ.pageid
    ,''
FROM TransportType AS TT 
     INNER JOIN #F AS FREQ ON FREQ.TransportTypeID = TT.TransportTypeId     
     INNER JOIN [Incident] AS INC on FREQ.Task = INC.Task AND FREQ.Contract = INC.Contract 
     INNER JOIN Calender ON CalanderDate = INC.[EstimatedCompletionStamp]
     INNER JOIN [IncidentStatus] AS INCSTAT ON INCSTAT.IncidentStatusID = INC.IncidentStatusID
     INNER JOIN [IncidentSubType] AS INCSTYP ON INCSTYP.incidentsubtypeid = INC.IncidentSubTypeID and INC.IncidentSubTypeID in (20,21,22,23) and INC.TransportTypeId = TT.TransportTypeID

列名称'CalanderDate'无效。当使用with和union时
