ASP.NET和Crystal Report：使用臨時表從存儲過程中加載數據源

Question

我已經使用一個存儲過程來實現我期望的輸出，以顯示一個購物中心/位置上的租戶單價銷售報告。 存儲過程包含多個臨時表（由於現有數據庫結構/架構的限制）來完成我需要完成的工作。 該過程在gridview中確實成功。

這是存儲過程

USE [DATABASENAME]
GO

ALTER PROCEDURE [dbo].[spName]
// parameters

@Location int, // the location number
@CurrentMonthStart date ,
@MonthCurrent varchar(20),
@MonthPrevious varchar(20)



AS
BEGIN
 //Using the CurrentMonthStart data, I formulated the other essential variable needed for the query to run
declare @PreviousMonthStart date
declare @PreviousMonthEnd date
declare @CurrentMonthEnd date
declare @query varchar (8000)

set @PreviousMonthStart  =   convert(varchar(10), DATEADD(m,-1, @CurrentMonthStart) , 101)
set @PreviousMonthEnd   =   convert(varchar(10), DATEADD(d,-1, @CurrentMonthStart) , 101)
set @CurrentMonthEnd    =   convert(varchar(10), DATEADD(d, -1, DATEADD(m,1, @CurrentMonthStart)) , 101)



// i used temp table several times
select b.tenantcode, b.date , SUM(a.other)as discount
        INTO #NewDiscountTable
        from DAILY a INNER JOIN DISCOUNT b on a.date = b.date and a.tenantcode = b.tenantcode 
        WHERE b.date between @PreviousMonthStart  AND @CurrentMonthEnd  and A.location = @Location 
        group by b.date, b.tenantcode 
        order by b.tenantcode 


        select tenantcode , SUM(discount) as Approved_Disc
        into #NewDiscountTableFinal
        from #NewDiscountTable 
        where  date between @PreviousMonthStart  AND @PreviousMonthEnd
        group by tenantcode

        select tenantcode , SUM(discount) as Approved_Disc2
        into #NewDiscountTableFinal2
        from #NewDiscountTable 
        where  date between @CurrentMonthStart AND @CurrentMonthEnd  
        group by tenantcode




select  b.sqm  as 'FLOOR AREA/SQM',  b.name as 'RETAIL PARTNERS' , 
        convert(varchar(10), a.date, 101) as Date, datename(weekday, a.date) as Day,
        ((sum(a.cash) + SUM(a.charge) + SUM(a.gift)+ SUM(a.other)) - (SUM(a.surcharge))) as GSC,
        a.location , a.tenantcode 
        into #NewDailySalesTenderTable
        from  TENANT b inner join LOCATION c on b.location=c.location inner join DAILY a on a.tenantcode=b.tenantcode

        where a.location = @Location and b.status  > 1 and
            a.date  BETWEEN  @PreviousMonthStart and @CurrentMonthEnd 

        GROUP BY  b.name, a.date , a.location , a.tenantcode , b.sqm
        order by b.name, A.DATE



        select  [FLOOR AREA/SQM], [RETAIL PARTNERS] , Tenantcode,  SUM(GSC) as GSCwithOtherDisc
        into #NewDailySalesTenderTableFinal 
        from #NewDailySalesTenderTable 
        where date  BETWEEN  @PreviousMonthStart and @PreviousMonthEnd
        GROUP BY [Retail Partners], tenantcode, [FLOOR AREA/SQM]
        ORDER BY [Retail Partners]



        select  [FLOOR AREA/SQM], [RETAIL PARTNERS] ,  Tenantcode,  SUM(GSC) as GSCwithOtherDisc2
        into #NewDailySalesTenderTableFinal2 
        from #NewDailySalesTenderTable 
        where  date between @CurrentMonthStart  AND @CurrentMonthEnd  
        GROUP BY [Retail Partners], tenantcode, [FLOOR AREA/SQM]
        ORDER BY [Retail Partners]



select A.[FLOOR AREA/SQM] , a.[Retail Partners], 

          case when a.tenantcode  in (select d.tenantcode from #NewDiscountTableFinal2 d ) -- case within case kasi pag 0 yung divisor may error
            then Round(((c.GSCwithOtherDisc2   - d.Approved_Disc2  )/(case when a.[FLOOR AREA/SQM] = 0 then null else (a.[FLOOR AREA/SQM]) end)   ),0)
            else Round(((c.GSCwithOtherDisc2  - 0)/ (case when a.[FLOOR AREA/SQM] = 0 then null else (a.[FLOOR AREA/SQM]) end) ),0)
            end as 'SALES/SQM',



            case when a.tenantcode  in (select d.tenantcode from #NewDiscountTableFinal2 d )
            then Round((c.GSCwithOtherDisc2   - d.Approved_Disc2  ),0)
            else Round((c.GSCwithOtherDisc2  - 0),0)
            end as CurrentMonth,

            case when a.tenantcode  in (select b.tenantcode from #NewDiscountTableFinal b )
            then Round((a.GSCwithOtherDisc  - b.Approved_Disc ),0)
            else Round((a.GSCwithOtherDisc  - 0),0)
            end as PreviousMonth


            --case when a.tenantcode  in (select b.tenantcode from #NewDiscountTableFinal b )
            --then Round((((((c.GSCwithOtherDisc2   - d.Approved_Disc2  )- (a.GSCwithOtherDisc  - b.Approved_Disc )) / (a.GSCwithOtherDisc  - b.Approved_Disc )) * 100)),0)
            --else Round((C.GSCwithOtherDisc2  - 0),0)
            --end as '%INC/DEC'

        into #FinalResult
        FROM #NewDailySalesTenderTableFinal  a left join  #NewDiscountTableFinal b on a.tenantcode = b.tenantcode join
        #NewDailySalesTenderTableFinal2 c on a.tenantcode = c.tenantcode left join #NewDiscountTableFinal2 d on c.tenantcode = d.tenantcode


 set @query = 'select [Retail Partners],[FLOOR AREA/SQM], ' +
'replace(convert(varchar,cast(([SALES/SQM])  as money),1), ''.00'','''') as ''SALES/SQM'',' +
'replace(convert(varchar,cast((CurrentMonth)  as money),1), ''.00'','''') as ' + @MonthCurrent  +
',replace(convert(varchar,cast((PreviousMonth)  as money),1), ''.00'','''') as ' + @MonthPrevious   +

',case when PreviousMonth = 0 
then ''N/A''' +
'else  replace(convert(varchar,cast(Round((((CurrentMonth-PreviousMonth)/ PreviousMonth    ) *100),0) as money),1), ''.00'','''') 
end as ''%INC/DEC'' ' +
'from #FinalResult '
 execute(@query)


END

我發現問題出在哪里存儲過程的最后一部分是沖突的根源。 我進行參數設置的部分-@MonthCurrent和@MonthPrevious查詢的生成列，這些列基於用戶選擇的內容。 我通過注釋掉那些部分以查看它是否可以在Crystal Report中運行並且確實做到了來隔離問題。

問題是：如何在Crystal REPORT中聯接這些列？

set @query = 'select [Retail Partners],[FLOOR AREA/SQM], ' +
    'replace(convert(varchar,cast(([SALES/SQM])  as money),1), ''.00'','''') as ''SALES/SQM'',' +
    'replace(convert(varchar,cast((CurrentMonth)  as money),1), ''.00'','''') as ' + @MonthCurrent  +
    ',replace(convert(varchar,cast((PreviousMonth)  as money),1), ''.00'','''') as ' + @MonthPrevious   +

    ',case when PreviousMonth = 0 
    then ''N/A''' +
    'else  replace(convert(varchar,cast(Round((((CurrentMonth-PreviousMonth)/ PreviousMonth    ) *100),0) as money),1), ''.00'','''') 
    end as ''%INC/DEC'' ' +
    'from #FinalResult '

示例屏幕截圖，在gridview中成功運行了SP

現在，我還要合並相同的存儲過程，這次使用所述SP作為我的數據源在Crystal Report中填充數據。 這是我開始的

 protected void Page_Load(object sender, EventArgs e)
    {
        con.Open();

//I pass the values of parameter from the page to the print page using Session
        Label1.Text = Session["Location"].ToString();
        int Loc = Convert.ToInt32(Label1.Text);

        Label2.Text = Session["CurrentMonthStart"].ToString();
        DateTime dt = Convert.ToDateTime(Label2.Text);

        Label3.Text = Session["MonthCurrent"].ToString();
        Label4.Text = Session["MonthPrevious"].ToString();


      report.Load(Server.MapPath("MonthlySalesReport.rpt"));

        CrystalReportViewer1.ReportSource = report;
        CrystalReportViewer1.ReuseParameterValuesOnRefresh = true;
        CrystalReportViewer1.DataBind();

        report.SetParameterValue(0, Loc);
        report.SetParameterValue(1, dt);
        report.SetParameterValue(2, Label3.Text);
        report.SetParameterValue(3, Label4.Text);

        con.Close();

    }

這是由存儲的pro中所述問題引起的錯誤

在結果集中找不到一個或多個字段。 使用驗證數據庫更新報告。 文件MonthlySalesReport {0E90B4CE-8D1A-4712-BE05-9C1DC8CC9ADB} .rpt中的錯誤：找不到行集列。

CR僅能讀取查詢返回的內容。 您可以在此處和此處看到類似的問題。 所有這些人都有類似的問題，就像您一樣棘手。 閱讀並查看是否有幫助。 如果沒有，請不要浪費時間找到解決方法。 如果我是你。 我創建了一個新表dbo.MyTempTable ，並在調用該過程時刷新它。

DELETE FROM dbo.MyTempTable
INSERT INTO dbo.myTempTable(Col1, Col 2, Col3, Col4 , Col5, Col6 ..)

    select [Retail Partners],[FLOOR AREA/SQM], ' +
    'replace(convert(varchar,cast(([SALES/SQM])  as money),1), ''.00'','''') as ''SALES/SQM'',' +
    'replace(convert(varchar,cast((CurrentMonth)  as money),1), ''.00'','''') as ' + @MonthCurrent  +
    ',replace(convert(varchar,cast((PreviousMonth)  as money),1), ''.00'','''') as ' + @MonthPrevious   +

    ',case when PreviousMonth = 0 
    then ''N/A''' +
    'else  replace(convert(varchar,cast(Round((((CurrentMonth-PreviousMonth)/ PreviousMonth    ) *100),0) as money),1), ''.00'','''') 
    end as ''%INC/DEC'' ' +
    'from #FinalResult '

在上面，您總是清空模板。 然后用查詢返回的值填充臨時表。

然后繼續並創建另一個過程或簡單地查看。 喜歡

CREATE PROCEDURE dbo.MyTempTableProcedure

AS 
  BEGIN 
     SELECT * FROM myTempTable
  END  

轉到您的報告，並將數據源更新為MyTempTableProcedure。 這是走動。 在您的后端C＃中。 打印結果之前，請先執行該步驟。 您將不會有任何問題，因為您已經使用過gridview。

        Label1.Text = Session["Location"].ToString();
        int Loc = Convert.ToInt32(Label1.Text);

        Label2.Text = Session["CurrentMonthStart"].ToString();
        DateTime dt = Convert.ToDateTime(Label2.Text);

        Label3.Text = Session["MonthCurrent"].ToString();
        Label4.Text = Session["MonthPrevious"].ToString();

       //EXECCUTE the procedure here
        using(SqlCommand cmd = new SqlCommand("spName",con)
        {
           cmd.CommandType = CommandType .StoredProcedure;
           cmd.Parameters.AddwithValue("@Location", LOC);
           cmd.Parameters.AddwithValue("@CurrentMonthStart ",   Label3.Text);
           cmd.Parameters.AddwithValue("@date ",   dt);
           cmd.Parameters.AddwithValue("@CurrentMonthStart ",   Label4.Text);

          cmd.ExecuteNonQuery();
        } 
        report.Load(Server.MapPath("MonthlySalesReport.rpt"));

        CrystalReportViewer1.ReportSource = report;
        CrystalReportViewer1.ReuseParameterValuesOnRefresh = true;

        con.Close();

這應該是一個散步。 這就是我的想法。 希望能幫助到你。
