laravel 如何删除所有排队的作业，因为它会导致错误？

How to remove all queued jobs because it's causing errors?

提问by Joshua Leung

My website queues email sending jobs to the jobstable. I think the email server has some problem and it can't send emails so the jobs are stuck at the jobs table. Now maybe there are too many jobs, and I receive this error message:

我的网站将电子邮件发送到jobs桌子上排队。我认为电子邮件服务器有一些问题，它无法发送电子邮件，因此作业卡在作业表中。现在可能有太多作业，我收到此错误消息：

Next exception 'Illuminate\Database\QueryException' with message 'SQLSTATE[22003]: Numeric value out of range: 1264 Out of range value for column 'attempts' at row 1 (SQL: update `jobs` set `reserved_at` = 1510263884, `attempts` = 256 where `id` = 342)' in /var/www/vhosts/parcgilley.com/httpdocs/vendor/laravel/framework/src/Illuminate/Database/Connection.php:647
#0 /var/www/vhosts/parcgilley.com/httpdocs/vendor/laravel/framework/src/Illuminate/Database/Connection.php(607): Illuminate\Database\Connection->runQueryCallback('update `jobs` s...', Array, Object(Closure))
#1 /var/www/vhosts/parcgilley.com/httpdocs/vendor/laravel/framework/src/Illuminate/Database/Connection.php(477): Illuminate\Database\Connection->run('update `jobs` s...', Array, Object(Closure))
#2 /var/www/vhosts/parcgilley.com/httpdocs/vendor/laravel/framework/src/Illuminate/Database/Connection.php(416): Illuminate\Database\Connection->affectingStatement('update `jobs` s...', Array)

So I am wondering how do I flush all the queued jobs to clear the table? I can't access the database to remove the data in the table, so is there any command line to do so? I don't have a failed queue table.

所以我想知道如何刷新所有排队的作业以清除表格？我无法访问数据库以删除表中的数据，那么是否有任何命令行可以这样做？我没有失败的队列表。

Assuming you are using database driver you can use:

假设您正在使用数据库驱动程序，您可以使用：

DB::table('jobs')->delete();

to delete all the jobs.

删除所有作业。

The other thing is that you should always run queue worker with attempts set:

另一件事是您应该始终运行带有尝试设置的队列工作器：

php artisan queue:work --tries=3

Also remember that whenever you change your application code, you should restart your workers:

还要记住，无论何时更改应用程序代码，都应该重新启动工作程序：

php artisan queue:restart

( I assume you use supervisor that will start workers again).

（我假设您使用将再次启动工人的主管）。
