c# - 带有链接子报表的 Crystal 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。

我的主要报告的存储过程

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

如果子报表正常工作，我检查了主报表预览

然后我运行报告，但我只看到这个 它只是停留在这条消息中并继续运行，我什至等待了几个小时并检查任务管理器是否挂起报告，但是没有..它也没有任何错误消息。但是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和链接中删除字段参数并重新运行报告。

它可以工作，但是如果不从主报告传递值就拥有报告是没有用的。因为我有日期范围。似乎是什么问题？为什么当我链接参数时它只是卡在加载报告？

有关详细信息，我正在使用 SAP Crystal Report 服务包 16 和 IDE 作为 Visual Studio 2015

这是我用于在主报告上获取/设置参数值的代码

 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这些属性:

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 上添加针对未知的优化主要:

子报告:

      group by M.MediaName
      order by M.MediaName
      OPTION (OPTIMIZE FOR (@StartDate2 UNKNOWN, @EndDate2 UNKNOWN))
        END

相同的结果，我认为来自主报告的结果没有通过子报告，因为它总是只在预览上工作，但在运行时只是停留在加载上。

我试过 sp_who2 Active 来检查是否被阻止。

顺便说一句，如果这有帮助的话，我正在我的 App.config 上使用这个连接..

 <?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">
    <probing privatePath="lib" />
  </assemblyBinding>
</runtime>
<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 中阅读所有相关内容。

第二种:查询中可以有一些读锁。如果报告数据不是那么敏感，您可以使用标准的 WITH(NOLOCK) 提示(READ UNCOMMITTED 隔离级别)。

尝试修改您的查询，使其看起来像这样并检查结果。

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。

附言无论如何检查 SQL Profiler 是否有传出查询。
