error-handling

问题 I have a .bat (Windows command) file that includes invocations of SQLCMD and other commands. (Of course SQLCMD is sending my T-SQL code to SQL Server.) I want to detect certain conditions in the SQL code, and conditionally exit the entire batch file. I've tried various combinations of RAISERROR, THROW, and deliberate division by 0 (I'm not proud) along with various command line switches on SQLCMD and handling of errorlevel in the .bat file. I tried the answer to 5789568 but could not get it

问题 I am trying download a directory inside s3 bucket. I am trying to use transfer to download a directory from S3 bucket but I am getting an error as "An error occurred (404) when calling the HeadObject operation: Not Found". Please help. S3 structure: **Bucket Folder1 File1** Note: Trying to download Folder1 transfer.download_file(self.bucket_name, self.dir_name, self.file_dir + self.dir_name) 回答1: I had the same issue recently. You are probably misspelling the path and folder name. In my case,

问题 The Question When creating a controller in Spring Boot to handle all errors/exceptions in a custom way, including custom exceptions , which technique should be preferred? Should the controller implement the Spring Boot's ErrorController ? Should the controller extend Spring's ResponseEntityExceptionHandler ? Both: a single controller implementing and extending both classes including both of their functionality? Both: two separate controllers, one implementing ErrorController , the other

问题 I'm new to C# comming from a python background. I'm currently trying to solve this challenge on codewars.com. It's about finding all the divisors to a number. I tried programming the following way public class Kata { public static int[] Divisors(int n) { List<int> divisors = new List<int>(); int i = 2, biggest_divisor = n; while (true) { if ( n % i == 0) { divisors.add(i); divisors.add(n/i); biggest_divisor = i; } if ( i > biggest_divisor) break; i++; } return divisors; } } I get this error

问题 I am aware of siiar questions, such as Angularjs 1.7.9 - Possibly unhandled rejection and those mentioned in it as duplicates. However, my code does not use promises (that I am aware of; certainly no $promise or $http ). I am just knocking up a simple ui-router demo for a friend. It is just two views, each with a button that toggles to the other view. It works just fine with AngulrJs 1.5, and breaks with the above error in 1.7. A simple as it is, it's a bit too much code to post. In case,
