SSRS2005報表只能在構建器和管理器中使用，而不能在查看器中使用

Question

我有一份我在VB2005中生成的報告。 它可以在報表構建器中完美運行，並且可以在服務器上的報表管理器中運行。

我有一個aspx頁面，但是帶有報表查看器，它返回0個結果。

報告呈現，但不返回任何數據。

這是我的SQL代碼：

SELECT        v_rpt_Company.Company_Name, SO_Activity.Subject, SO_Activity.Notes, SO_Activity.Date_Closed, SO_Activity.Last_Update, v_rpt_Member.Member_ID, 
                         v_rpt_ActivityType.SO_Activity_Type_Desc, v_rpt_ActivityStatus.SO_Act_Status_Desc
FROM            v_rpt_Company LEFT OUTER JOIN
                         SO_Activity ON v_rpt_Company.Company_RecID = SO_Activity.Company_RecID LEFT OUTER JOIN
                         v_rpt_Member ON SO_Activity.Assign_To = v_rpt_Member.Member_ID LEFT OUTER JOIN
                         Company_Team ON v_rpt_Member.Member_RecID = Company_Team.Member_RecID AND 
                         v_rpt_Company.Company_RecID = Company_Team.Company_RecID LEFT OUTER JOIN
                         v_rpt_ActivityType ON SO_Activity.SO_Activity_Type_RecID = v_rpt_ActivityType.SO_Activity_Type_RecID LEFT OUTER JOIN
                         v_rpt_ActivityStatus ON SO_Activity.so_act_status_recid = v_rpt_ActivityStatus.SO_Act_Status_RecID
WHERE        (@acctmgr <> 'true' OR Company_Team.AcctMgr_Flag = 1) AND 
                         (SO_Activity.Assign_To = @member) AND (v_rpt_ActivityStatus.SO_Act_Status_Desc = CASE WHEN @act_status IS NULL 
                         THEN v_rpt_ActivityStatus.so_act_status_desc ELSE @act_status END) AND ((@company = '') OR (v_rpt_Company.Company_RecID = @company)) AND (SO_Activity.Last_Update >= CONVERT(datetime, @date_start, 101)) AND (SO_Activity.Last_Update <= CONVERT(datetime, @date_end, 101))
GROUP BY v_rpt_Company.Company_Name, SO_Activity.Subject, SO_Activity.Notes, SO_Activity.Date_Closed, SO_Activity.Last_Update, v_rpt_Member.Member_ID, 
                         v_rpt_ActivityType.SO_Activity_Type_Desc, v_rpt_ActivityStatus.SO_Act_Status_Desc
ORDER BY v_rpt_Company.Company_Name, SO_Activity.Last_Update DESC

這是我的asp.net代碼：

<div style="text-align:center;border-style:solid;border-width:3px; width:auto;height:auto;">
    <rsweb:ReportViewer ID="ReportViewer1" runat="server" Font-Names="Verdana" Font-Size="8pt"
        Height="700px" ProcessingMode="Remote" Width="100%" ShowParameterPrompts="False">
        <ServerReport ReportPath="/path/report" ReportServerUrl="http:myserver/reportserver" />
    </rsweb:ReportViewer>
</div>

這是我的C＃：

   /*
     * Retrieve parameters from URL and send them to the report
     */
    private void getParametersFromURL()
    {
        //Load Parameters from URL
        //Requests that are commented, are commented because of lack of ConnectWise Support
        String[] parameters = new String[7];
        parameters[0] = Request.QueryString["acctmgr"];
        parameters[1] = Request.QueryString["member"];
        parameters[2] = Request.QueryString["details"];
        parameters[3] = Request.QueryString["act_status"];
        parameters[4] = Request.QueryString["company"];
        parameters[5] = Request.QueryString["date_start"];
        parameters[6] = Request.QueryString["date_end"];

        //Create Parameter Collection Array
        Microsoft.Reporting.WebForms.ReportParameter[] reportParameterCollection = new Microsoft.Reporting.WebForms.ReportParameter[parameters.Length];
        //Loop through each parameter and load the name and value into the parameter collection
        int i = 0;
        foreach (String parameter in parameters)
        {
            reportParameterCollection[i] = new Microsoft.Reporting.WebForms.ReportParameter();
            reportParameterCollection[i].Name = getParameterName(i);
            reportParameterCollection[i].Values.Add(Convert.ToString(parameters[i]));
            i++;
        }

        //Load Parameters into the ReportViewer
        ReportViewer1.ServerReport.SetParameters(reportParameterCollection);
        ReportViewer1.ServerReport.Refresh();
    }

    /*
     * Takes the index of the element in the parameter array 
     * then returns the correct parameter name to return to the report viewer
     */
    public String getParameterName(int number)
    {
        switch (number)
        {
            case 0:
                return "AcctMgr";
            case 1:
                return "member"; 
            case 2:
                return "details";
            case 3:
                return "act_status";
            case 4:
                return "company";
            case 5:
                return "date_start";
            case 6:
                return "date_end";
            default:
                Response.Write("<script language='javascript'>alert('Error: getParameterName(number) failed. Parameter #: " + number + ");</script>");
                return "error";
        }
    }

Answer 1

我修好了它。 問題是act_status

根據reportviewer的說法，顯然是帶有&act_status=&...的url字符串，並不意味着act_status = NULL 。

因此，我更改了SQL以反映空字符串而不是NULL。
