带有链接子报表的水晶报表仅适用于报表预览

Question

我在我的主报告中使用了带有 sql 参数的存储过程。

我的主报告的存储过程

然后我尝试使用以下存储过程在工作报告中添加子报告

然后将 Subreport 字段参数链接到我的 Main

如果子报告正常工作，我检查了主报告预览

然后我运行报告，但我看到的只是这个 它只是停留在此消息中并继续运行，我什至等待了几个小时并检查任务管理器是否挂起报告，但没有..它也没有任何错误消息。但为了关闭正在运行的报告，我必须在任务管理器中“结束进程”。

所以我尝试从子报告以及链接中删除字段参数并重新运行报告。

它可以工作，但是如果没有从主报告中传递值，则生成报告是没有用的。因为我有日期范围。似乎是什么问题？为什么我链接参数时它只是停留在加载报告？

有关更多信息，我正在使用 SAP Crystal Report Service Pack 16，以及作为 Visual Studio 2015 的 IDE

这是我用于获取/设置主报告参数值的代码

 private void SalesByRangeReport_Load(object sender, EventArgs e)
    {

        FormBorderStyle = FormBorderStyle.Sizable;

        WindowState = FormWindowState.Maximized;

        TopMost = true;

        DataTable dtSalesByRangeReport = GetData();

        showReport(dtSalesByRangeReport);
    }

    private void showReport(DataTable dtSalesByRangeReport)
    {
        ReportDocument rdoc = new ReportDocument();

        //rdoc.Load(@"Report\SalesByRangeReport.rpt");

        rdoc.Load(AppDomain.CurrentDomain.BaseDirectory + @"Report\SalesByRangeReport.rpt");
        rdoc.SetDataSource(dtSalesByRangeReport);

        TextObject txt;
        if (rdoc.ReportDefinition.ReportObjects["test"] != null)
        {
            txt = (TextObject)rdoc.ReportDefinition.ReportObjects["test"];
            txt.Text = "From :" + StartDate.ToString(" MMMM  dd  yyyy  hh :mm") + " To :" + EndDate.ToString(" MMMM  dd  yyyy  hh :mm");
        }

        SalesByRangeCystalReport.ReportSource = rdoc;
    }


 private DataTable GetData()
    {
        DataTable dtData = new DataTable();

        using (SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["CSPOSWare.Reports.Properties.Settings.fpos_chaplinConnectionString"].ConnectionString))
        {

            //TODO Mark and Reni : Create a Stored Procedure, Saved in SalesByRangeReport.txt 

            using (SqlCommand cmd = new SqlCommand("usp_ReportShowSalesRangeDateTime", conn))
            {
                cmd.CommandType = CommandType.StoredProcedure;

                conn.Open();

                //cmd.Parameters.AddWithValue("@TopInt", this.TopInt);
                cmd.Parameters.AddWithValue("@SortType", this.SortType);
                cmd.Parameters.AddWithValue("@StartDate", this.StartDate);
                cmd.Parameters.AddWithValue("@EndDate", this.EndDate);
                cmd.Parameters.AddWithValue("@DeptGroup", this.DeptGroup);
                cmd.Parameters.AddWithValue("@DateType", this.DateType);

                //Console.WriteLine("Start Date" + StartDate);

                SqlDataReader rdr = cmd.ExecuteReader();

                dtData.Load(rdr);
            }

        }


        return dtData;
    }

我的两个报告都具有以下属性：

Build Action: Compile
Copy to Output Directory: Copy Always
Custom Tool: 
Custom Tool Name: 

所以我尝试在我的主 SP 和子 SP 上为未知数添加优化 主要：

                    OPTION (OPTIMIZE FOR (@StartDate UNKNOWN, @EndDate UNKNOWN))
                END

子报告：

    ALTER PROCEDURE[dbo].[usp_ReportShowMedia](

                @EndDate2      DATETIME

      LEFT JOIN Media M WITH(NOLOCK) ON M.MediaIndex = T.MediaIndex
      Where   StoreDate   BETWEEN  convert(VARCHAR,@StartDate2)   AND        convert(VARCHAR,@EndDate2) 
      group by M.MediaName
      order by M.MediaName
      OPTION (OPTIMIZE FOR (@StartDate2 UNKNOWN, @EndDate2 UNKNOWN))
        END

同样的结果，我认为主报告中的结果并没有通过子报告，因为它总是只在预览中工作，但在运行时只是卡在加载中。

我试过 sp_who2 Active 检查是否被阻止。

顺便说一句，如果这有帮助，我正在我的 App.config 上使用此连接..

 <?xml version="1.0" encoding="utf-8" ?>
 <configuration>
<startup useLegacyV2RuntimeActivationPolicy="true"> 
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5.2" />
</startup>
<runtime>
  <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">

  </assemblyBinding>

<connectionStrings>
  <add name="CSPOS.Reports.Properties.Settings.chaplinConnectionString" connectionString="Data Source=RENZ\SQLEXPRESS;Initial Catalog=erika;Integrated Security=True" providerName="System.Data.SqlClient"/>
 </connectionStrings>
 </configuration>

我检查了 master 上的数据库权限

Answer 1

有一天我遇到了这样的情况。主要问题是存储过程中不同参数的执行计划不正确。

它可以通过 OPTION (OPTIMIZE FOR (@param UNKNOWN) 修复。您可以在here 中阅读所有相关信息。

第二个：查询中可能存在一些读锁。如果报告数据不那么敏感，您可以使用标准 WITH(NOLOCK) 提示（READ UNCOMMITTED 隔离级别）。

尝试将您的查询修改为如下所示并检查结果。

SELECT 
...
FROM CSSale S WITH(NOLOCK)
LEFT JOIN (... FROM CSSaleItem WITH(NOLOCK) ...)
LEFT JOIN CSSaleTender T WITH(NOLOCK) ...
LEFT JOIN Media M WITH(NOLOCK)
ORDER BY M.MediaName
OPTION (OPTIMIZE FOR (@StartDate2 UNKNOWN, @EndDate2 UNKNOWN))

您还需要检查用于主查询的存储过程是否存在相同问题。

附：无论如何检查 SQL Profiler 是否有传出查询。

Answer 2

让我们尝试找出问题是否与存储过程有关。

尝试通过将参数插入到某个虚拟表 (dbo.subReportParamsTb) 作为 SP 的第一条语句来捕获传递给子报表的存储过程 (dbo.usp_ReportShowMedia) 的参数。

INSERT INTO dbo.subReportParamsTb(
StartDate2,
EndDate2
) 
VALUES (
@StartDate2,
@EndDate2
);

在运行主报告后，当您看到卡住的消息时，请检查 dbo.subReportParamsTb 的包含情况，并且没有锁定。

SELECT *
FROM dbo.subReportParamsTb WITH(NOLOCK);

如果您看到参数已成功传递给 SP，请尝试使用这些参数独立运行 SP。

如果 SP 没有在有限的时间内产生输出，您可以尝试通过查看执行计划来进一步排除故障。

如果 SP 运行正常，您可以确定问题不在于 SP。

Answer 3

我认为这可能是两个报告之间的数据链接问题。请确保主报告和子报告具有唯一的 ID 并正确链接。

Answer 4

我通过使用两个 sqlcommand 解决了这个问题，并消除了存储过程的使用。谢谢顺便说一句。
