存储过程中的列无效

Question

我在存储过程中有一个查询，它工作正常。 现在我想添加一列显示错误。

我的存储过程代码为：

ALTER PROCEDURE dbo.test
      @SDate DATETIME =Null
    , @EDate DATETIME=Null
    ,@period int=Null        
AS BEGIN         
    SET NOCOUNT ON;

    if @period = 1 
    Begin 
       SELECT 
              t.TotalQuote
            , t.QuoteAmount        
            ,t.avgProbQ
            , t2.TotalOrders
            , t2.OrderAmount       
             ,t3.totalSales
            ,t3.Prob
        FROM (SELECT a = 1) a
        CROSS JOIN (
            SELECT 
                  TotalQuote = COUNT(quoteid)
                , QuoteAmount = SUM(totalamount)
                ,avgProbQ=SUM(CloseProbability)/COUNT(CloseProbability)
            FROM dbo.QuoteBase join dbo.OpportunityBase on dbo.QuoteBase.opportunityid=dbo.OpportunityBase.opportunityid   
            WHERE
              Month(dbo.QuoteBase.CreatedOn)=Month(getdate()) And YEAR(dbo.QuoteBase.CreatedOn)=YEAR(GETDATE())
        ) t
        CROSS JOIN (
            SELECT 
                  TotalOrders = COUNT(salesorderid)
                , OrderAmount = SUM(totalamount) 
            FROM dbo.SalesOrderBase join dbo.OpportunityBase on dbo.SalesOrderBase.Opportunityid=dbo.OpportunityBase.Opportunityid 
         Where Month(dbo.SalesOrderBase.CreatedOn)=Month(getdate()) And YEAR(dbo.SalesOrderBase.CreatedOn)=YEAR(GETDATE())
        ) t2
        CROSS Join(
        SELECT
        TotalSales=COUNT(dbo.OpportunityBase.opportunityid)
        ,Prob=SUM(CloseProbability)/COUNT(CloseProbability)

        FROM dbo.OpportunityBase join dbo.SalesorderBase on dbo.SalesOrderBase.Opportunityid=dbo.OpportunityBase.Opportunityid
            WHERE Month(dbo.OpportunityBase.CreatedOn)=Month(getdate()) And YEAR(dbo.OpportunityBase.CreatedOn)=YEAR(GETDATE())
            And dbo.SalesorderBase.StateCode=4
            )t3
    END

它工作正常，但是当我添加新列如t.test ，则显示错误

消息207，第16级，状态1，程序测试，第23行
无效的列名“ test”。

如果有人有想法请与我分享

我不确定您的表是什么样子，似乎您正在向存储过程中添加测试，但未将其添加到数据库表中

这是我可以通过查看错误消息说的话。 希望能帮助到你

Answer 2

不确定要执行的操作，但是猜测，如果要在存储过程的输出中添加一列，而不是存储过程从中读取数据的表中的列，则必须放置一个文字表达式到select子句中，并具有如下定义的列名：此示例使用字符串文字，但可以是任何数据类型...

 SELECT 'A String literal to be added to output' As  NewColumnName,
      t.TotalQuote
    , t.QuoteAmount        
    ,t.avgProbQ
    , t2.TotalOrders
    , t2.OrderAmount       
     ,t3.totalSales
    ,t3.Prob
  etc....

您收到此错误，因为此查询中不存在列test ：

CROSS JOIN (
    SELECT 
          TotalQuote = COUNT(quoteid)
        , QuoteAmount = SUM(totalamount)
        ,avgProbQ=SUM(CloseProbability)/COUNT(CloseProbability)
    FROM dbo.QuoteBase join dbo.OpportunityBase on dbo.QuoteBase.opportunityid=dbo.OpportunityBase.opportunityid   

    WHERE
      Month(dbo.QuoteBase.CreatedOn)=Month(getdate()) And YEAR(dbo.QuoteBase.CreatedOn)=YEAR(GETDATE())
) t

但是，如果您要向该查询添加名为test的列，则它将成功。 如有必要，它可以是字符串文字，例如'Some literal value' AS test 。
