The following editor will bring you a brief discussion of MySQL event planning tasks. The editor thinks it’s pretty good, so I’ll share it with you now and give it as a reference. Let’s follow the editor and take a look.

1. Check whether the event is turned on

##show variables like '%sche%';

set global event_scheduler =1;

2.

--Set the time zone and set the planned event scheduler to turn on, or event_scheduler = ON

set time_zone = '+8:00';
set GLOBAL event_scheduler = 1;

--Set the database base database that the event uses or belongs to

use test;

-- If there is a task plan with this name, delete it first

drop event if exist test_update;

-- Set the separator to '$$', the default statement separator of mysql is ';' , so that the subsequent code from create to end will be regarded as a statement to execute

DELIMITER $$

-- Create a scheduled task and set the first execution time to '2012-11-15 10:00:00', and executed once a day

-- on schedule every 30 second

-- on schedule every day starts timestamp '2012-11-15 10:00:00'

create event test_update

on schedule every day starts timestamp '2012-11-15 10:00:00'
do

-- What to do when starting this scheduled task

begin

-----------------------------------

-- do something write What your planned task will do
-----------------------------------

-- End scheduled task

end $$

-- Set the statement delimiter back to ';'

DELIMITER ;
