Question

我在客户端的生产服务器上发生SQL异常（我几乎没有权利）。

我无法在本地复制问题，但有没有什么好方法可以找出并调查sql异常被调用以及使用哪个sql？我可以重新部署并有权更改源代码。

我的堆栈跟踪是这样的：

An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.  

Stack Trace:
[SqlException (0x80131904):  ]

尝试使用以下方法收集有关异常的更多信息（取自MSDN article）：

    try
    {
        command.Connection.Open();
        command.ExecuteNonQuery();
    }
    catch (SqlException ex)
    {
        for (int i = 0; i < ex.Errors.Count; i++)
        {
            errorMessages.Append("Index #" + i + "\n" +
                "Message: " + ex.Errors[i].Message + "\n" +
                "LineNumber: " + ex.Errors[i].LineNumber + "\n" +
                "Source: " + ex.Errors[i].Source + "\n" +
                "Procedure: " + ex.Errors[i].Procedure + "\n");
        }
        Console.WriteLine(errorMessages.ToString());
    }
