MYSQL的JOB
要让JOB顺利运行,必须要打开MYSQL的定时器。
-- 查看是否开启定时器 SHOW VARIABLES LIKE '%sche%'; -- 开启定时器 0:off 1:on
-- 这个需要最高权限打开,否则会提示(无权限):you need (at least one of) the CREATE USER privilege(s) for this operation SET GLOBAL event_scheduler = 1;
-- 创建事件 --每隔一秒自动调用e_test()存储过程 CREATE EVENT IF NOT EXISTS event_test ON SCHEDULE EVERY 1 SECOND ON COMPLETION PRESERVE DO CALL e_test(); -- 开启事件 ALTER EVENT event_test ON COMPLETION PRESERVE ENABLE; -- 关闭事件 ALTER EVENT event_test ON COMPLETION PRESERVE DISABLE;
