无法使用cmd.exe在C＃中完成sqlldr命令的执行

Question

I am trying to execute sqlldr command in C# code(scheduler) by calling it in cmd.exe. I am executing a command to INSERT records in one of the table of ORACLE 10g database. But the output I am getting from command execution is incomplete and it is given as follows,

SQL*Loader: Release 11.2.0.2.0 - Production on Mon Nov 6 16:23:22 2017
Copyright (c) 1982, 2009, Oracle and/or its affiliates.  All rights reserved.

Below mentioned coding, I have done to execute SQL loader command.

string strCommand = "sqlldr userid=Username/Password@DBNAME, control=xyz.ctl, log=pqr.log";

            objProcStartInfo = new System.Diagnostics.ProcessStartInfo("cmd.exe", "/c " + strCommand);
            //objProcStartInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
            objProcStartInfo.RedirectStandardOutput = true;
            objProcStartInfo.UseShellExecute = false;
            // Do not create the black window.
            objProcStartInfo.CreateNoWindow = false;

            objProcStartInfo.RedirectStandardError = true;

            objProcess = new System.Diagnostics.Process();
            objProcess.StartInfo = objProcStartInfo;

            if (!objProcess.Start())
            {
                ErrorLog.LogError("Scheduler Info.", "Due to some technical reason the process of SQL loader could not started.");
            }
            else
            {
                // Get the output into a string
                string strResult = objProcess.StandardOutput.ReadToEnd();
                // Display the command output.
                Console.WriteLine(strResult);

                if (!string.IsNullOrEmpty(strResult))
                    ErrorLog.LogError("Scheduler Info.", "Output of SQL loader command :- " + strResult);
            }

If anyone has done this, kindly provide suggestion/solution.

Answer 1

I found the main problem. When I cross checked the table columns of database with columns mentioned. Ctl file, I found the mismatch in columns sequence. With corrected the column sequence when I executed the sqlldr command. It executed swiftly.
