Question

我有一个复杂的查询，它将东西填充到临时表中，然后读取并组合这些临时表。最后，我有这段代码：

    Select distinct CSDirector=r1.CSDirector,
        Category = r1.Category,
        Segment = r1.Segment,
        r1.unit,
        NumUnits=r1.NumUnits,
        NumUnitsLast=r2.NumUnits,
        MonthSales=r1.MonthSales,
        MonthSalesLast=r2.MonthSales,
        MonthPerc = (r1.MonthSales - r2.MonthSales) / case when isnull(r2.MonthSales,0) = 0 then 1 else r2.MonthSales end, 
        YTDSales = r1.YTDSales, 
        YTDSalesLast = r2.YTDSales,
        YTDPerc= (r1.YTDSales - r2.YTDSales) / case when isnull(r2.YTDSales,0) = 0 then 1 else r2.YTDSales end,
        ProjSales = r1.ProjSales, 
        YTDProjSales = r1.YTDProjSales,
        YTDBudgetPerc = r1.YTDBudgetPerc,
        NewBiz = isnull((Select NewBiz from MasterUnitsProjSales where Unit = r1.unit and Cyear=@Cyear),0)  
into    #CombinedYears
From #CurrentYear r1 inner join #PriorYear r2 on r1.unit=r2.unit
order by NewBiz,r1.Unit

declare @Unit varchar(30);
declare @paramdate datetime;
set @paramdate = convert(datetime,convert(char(4),@CYear)
                +right('0'+convert(varchar(2),@CMonth),2)
                +'01') 

IF OBJECT_ID('tempdb.dbo.#Units', 'U') IS NOT NULL
DROP TABLE #Units

select distinct unit
into #Units
from ReportingMonthlySales;

select 
    u.Unit
  , New      = sum(case when ccl.Subcategory = 'New'      then rms.MonthlySales else 0 end)
  , Assumed  = sum(case when ccl.Subcategory = 'Assumed'  then rms.MonthlySales else 0 end)
  , Existing = sum(case when ccl.Subcategory = 'Existing' then rms.MonthlySales else 0 end)
  , Organic  = sum(case when ccl.Subcategory = 'Organic'  then rms.MonthlySales else 0 end)
into    #CategorizedUnits
from #Units u
join CustomerCategoryLog   ccl on u.Unit = ccl.Unit and @paramdate >= ccl.begindate and @paramdate <= ccl.enddate
join ReportingMonthlySales rms on u.Unit = rms.Unit and rms.cyear  = @cyear and rms.cmonth = @cmonth
group by u.unit;

-- Now combine combined years and categorized units
select CY.CSDirector, CY.Category, CY.Segment, CY._Unit, 
       CU.New, CU.Assumed, CU.Existing, CU.Organic, 
       CY.NumUnits, CY.NumUnitsLast, CY.MonthSales, CY.MonthSalesLast, 
       CY.MonthPerc, CY.YTDSales, CY.YTDSalesLast, CY.YTDPerc,
       CY.ProjSales, CY.YTDProjSales, CY.YTDBudgetPerc, CY.NewBiz 
from #CombinedYears CY
left join #CategorizedUnits CU on CU.Unit = CY.Unit

...但是它失败了＆＃34; 错误207：列名无效＆＃39; r1＆＃39;。＆＃34;在这一行：

select CY.CSDirector, CY.Category, CY.Segment, CY.r1.unit,

所以，我想也许我需要改变这个：

Select distinct CSDirector=r1.CSDirector,
        Category = r1.Category,
        Segment = r1.Segment,
        r1.unit,

......对此：

Select distinct CSDirector=r1.CSDirector,
        Category = r1.Category,
        Segment = r1.Segment,
        _Unit = r1.unit,

......以及：

select CY.CSDirector, CY.Category, CY.Segment, CY.r1.unit,

......对此：

select CY.CSDirector, CY.Category, CY.Segment, CY._Unit,

...但是当我尝试时，我得到了＆＃34; 错误207：列名无效＆＃39; _Unit＆＃39;。＆＃34;在这一行：

select CY.CSDirector, CY.Category, CY.Segment, CY._Unit,

那么我怎样才能抓住＆＃34; Unit＆＃34;来自#CombinedYears表的值？

更新

这也失败了：

--select CY.CSDirector, CY.Category, CY.Segment, CY.r1.unit, 
--select CY.CSDirector, CY.Category, CY.Segment, CY._Unit, 
select CY.CSDirector, CY.Category, CY.Segment, CY.unit,

...使用＆＃34; 错误207：列名称无效＆＃39;单位＆＃39;。＆＃34;

Answer 1

开始...

select * from #CombinedYears

应该能够识别字段名称或者在下面的查询中明确命名字段... [_ Unit]。

  Select distinct CSDirector=r1.CSDirector,
        Category = r1.Category,
        Segment = r1.Segment,
        r1.unit [_Unit],   -- here
        NumUnits=r1.NumUnits,
        NumUnitsLast=r2.NumUnits,
        MonthSales=r1.MonthSales,
        MonthSalesLast=r2.MonthSales,
        MonthPerc = (r1.MonthSales - r2.MonthSales) / case when isnull(r2.MonthSales,0) = 0 then 1 else r2.MonthSales end, 
        YTDSales = r1.YTDSales, 
        YTDSalesLast = r2.YTDSales,
        YTDPerc= (r1.YTDSales - r2.YTDSales) / case when isnull(r2.YTDSales,0) = 0 then 1 else r2.YTDSales end,
        ProjSales = r1.ProjSales, 
        YTDProjSales = r1.YTDProjSales,
        YTDBudgetPerc = r1.YTDBudgetPerc,
        NewBiz = isnull((Select NewBiz from MasterUnitsProjSales where Unit = r1.unit and Cyear=@Cyear),0)  
into    #CombinedYears
From #CurrentYear r1 inner join #PriorYear r2 on r1.unit=r2.unit
order by NewBiz,r1.Unit

如何访问临时表的此字段？
