【问题描述】：
好的，大约 3-4 分钟后，我一直收到此错误：
Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Data.SqlClient.SqlException: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.
Source Error:
Line 93:
Line 94: DataSet getData;
Line 95: getData = SqlHelper.ExecuteDataset(ConfigurationManager.ConnectionStrings["connstr"].ConnectionString, CommandType.StoredProcedure, "Course_NewReportGet_Get_Sav", objPara);
Line 96:
Line 97: foreach (DataRow dr in getData.Tables[0].Rows)
这是代码，我认为我没有正确执行某些操作，但我将超时设置为 5000 秒，所以它必须是其他内容。您会注意到它完全是过程调用的嵌套循环。我得到每家公司，然后得到分配给每家公司的每门课程，然后对于每门课程，我得到所有用户活动的报告。大约有 250 家公司，每家公司有 2-70 门课程，每家公司每门课程报告有 8 到 1000 名用户……所以我们在这里处理大量数据。对 get 报告的最后调用也是一个相当庞大的存储过程......
我正在尝试将数据转换为一种新形式，以便以后使用起来更快、更容易，但现在我必须解析我们拥有的内容并以新的方式发布。这一切都在同一个数据库中，但我不确定如何仅在 SQL 中完成这一切。基本上我正在使用我们的报告工具使用的存储过程来获取要发布到新表的数据。但是我需要为每家公司的每门课程运行该程序，然后发布每家公司每门课程的报告中返回的每个用户的数据......这是巨大的......

我不能确切地知道你想要达到的最终结果是什么，但看起来你应该能够在数据库的一次往返中做到这一点，而不是你目前的方式有它。我认为这应该可以为您节省大量时间。

是的，我也在想同样的事情，但如果我能让它像这样工作，那么工作量就会少得多，因为这只是一次数据转换。
