使用 Laravel 迁移创建一个 mysql 事件？

Question

Is there any way to create a mysql event using laravel migration? If yes how?

Answer 1

Don't use DB::statement(''), as the event creation needs to be on unprepared mode. Use the following:

DB::unprepared('Your event creation code goes here')

Answer 2

You can use DB::statement() . More details here .

DB::statement('CREATE EVENT my_event ...')

Answer 3

DB::unprepared(" CREATE EVENT IF NOT EXISTS delete_etiqueta_rendimento_pack ON SCHEDULE EVERY 1 DAY STARTS '2020-04-21 01:00:27' ON COMPLETION NOT PRESERVE ENABLE COMMENT 'Deletes all record redimento_pack from 3 months ago' DO BEGIN DELETE FROM rendimento_packing WHERE data_hora < DATE_SUB(NOW(), INTERVAL 3 MONTH); END ");

If you use DB::statement('') probabli you gonne a see this error: SQLSTATE[HY000]: General error: 2014 Cannot execute queries while other unbuffered queries are active. Consider using PDOStatement::fetchAll(). Alternatively, if your code is only ever going to run against mysql, you may enable query buffering by setting the PDO::MYSQL_ATTR_USE_BUFFERED_QUERY attribute.
