Dont know how to solve, it. I am getting this error at the last line. SqlCmd.ExecuteNonQuery();


Any Ideas.


Here is the Code, Cut and paste to VS.NET.            


                                  #region public static LogErrorToSqlServer
            static public void LogErrorToSQLServer(
                                          int errorCode,
                                          string errorSource,
                                          string errorCulture,
                                          string errorMessage)
            {
                  SqlConnection SqlConn = null;
                  SqlCommand SqlCmd = null;
                  
                  try
                  {
                        SqlConn = new SqlConnection(Common.DataBaseConnectionString);
                        SqlCmd = new SqlCommand("spInsertError",SqlConn);
                        SqlCmd.CommandType = CommandType.StoredProcedure;
                        
                        SqlParameter paramServer = new SqlParameter("@Server",SqlDbType.VarChar,8);
                        paramServer.Value = System.Web.HttpContext.Current.Server.MachineName;
                        paramServer.Direction = ParameterDirection.Input;
                        SqlCmd.Parameters.Add(paramServer);
                  
                        SqlParameter paramPageURL = new SqlParameter("@PageURL",SqlDbType.VarChar,127);
                        paramPageURL.Value = System.Web.HttpContext.Current.Request.Url;
                        paramPageURL.Direction = ParameterDirection.Input;
                        SqlCmd.Parameters.Add(paramPageURL);

                        SqlParameter paramQueryString = new SqlParameter("@QueryString",SqlDbType.VarChar,127);
                        paramQueryString.Value = System.Web.HttpContext.Current.Request.QueryString;
                        paramQueryString.Direction  = ParameterDirection.Input;
                        SqlCmd.Parameters.Add(paramQueryString);

                        SqlParameter paramSource = new SqlParameter("@ErrorSource",SqlDbType.VarChar,32);
                        paramSource.Value = errorSource;
                        paramSource.Direction  = ParameterDirection.Input;
                        SqlCmd.Parameters.Add(paramSource);

                        SqlParameter paramCode = new SqlParameter("@ErrorCode",SqlDbType.Int,4);
                        paramCode.Value = errorCode;
                        paramCode.Direction = ParameterDirection.Input;
                        SqlCmd.Parameters.Add(paramCode);

                        SqlParameter paramCulture = new SqlParameter("@ErrorCulture",SqlDbType.VarChar,8);
                        paramCulture.Value = errorCulture;
                        paramCulture.Direction = ParameterDirection.Input;
                        SqlCmd.Parameters.Add(paramCulture);

                        SqlParameter paramMessage = new  SqlParameter("@ErrorMessage",SqlDbType.VarChar,512);
                        paramMessage.Value = errorMessage;
                        paramMessage.Direction = ParameterDirection.Input;
                        SqlCmd.Parameters.Add(paramMessage);

                        SqlConn.Open();
                        SqlCmd.ExecuteNonQuery();
                  }
                  catch (Exception ex)
                  {
                        ex.ToString();
                  }
                  finally
                  {
                        
                        if (SqlCmd != null) SqlCmd.Dispose();
                        if (SqlConn != null) { if (SqlConn.State != System.Data.ConnectionState.Closed) SqlConn.Close(); SqlConn.Dispose(); }
                  }
            }

it's also possible that you might be trying to send a C# null value to the stored procedure when the stored procedure might allow a DbNull which is different than a C# null.

But now that I've spit that out, I think it actually throws a different error than what you've provided.


follw dfiala's suggestion and if some reason that doesn't pan out, then look for a data error

In this case one of your parameters is not the type you expect.  Double check the signature on your stored proc. Could also be some funky characters in your query string param.  Brute force case, strip down to one param and add them in until one breaks.

Also... if you post the header to the stored procedure someone here may be able to point out your error (if you can't find it).
