Below is the Event which I have written to be executed every day. I ran the SET GLOBAL event_scheduler = ON; before creating the event still it excutes only first day but from next day onwards it will not run.
Is there anything wrong in this query?
DELIMITER $$
ALTER DEFINER=`root`#`localhost` EVENT `Event1` ON SCHEDULE EVERY 1 DAY STARTS '2017-03-15 00:00:00' ON COMPLETION NOT PRESERVE ENABLE DO CALL UpdateLeaves()$$
DELIMITER ;
...ON COMPLETION NOT PRESERVE...
change to
...ON COMPLETION PRESERVE...

I have a Mysql Event based on this answer:
https://stackoverflow.com/a/41099947/9478434
My Event is:
DELIMITER $$
CREATE
DEFINER=`db_admin`#`%`
EVENT dbname.my_event
ON SCHEDULE
EVERY 1 DAY
STARTS '2018-05-30 22:58:00'
COMMENT 'Do Archive old posts'
DO
BEGIN
CALL stored_procedure_1();
CALL stored_procedure_2();
END;
END $$
DELIMITER ;
But it does not run at the time it should run. I checked the event_scheduler variable and it is ON and in the processlist there is a record with Command: Sleep.
I have the following script. The scripts runs but what i want is for it to run every 5 minutes following the wall clock time. Meaning it should run at 5, 10, 15 ... following the wall clock time at 5 minitues interval. What I can gauge for the result of the run is that the time is 10 - 30 seconds off. Is there a way to get it closer to the 5 minutues mark?. Thanks.
CREATE DEFINER=`root`#`%`
EVENT `run_event`
ON SCHEDULE EVERY 5 MINUTE STARTS '2016-04-06 00:00:00'
ON COMPLETION NOT PRESERVE ENABLE
DO CALL my_procedure
Your configuration seems correct. The timing of events is not extremely precise, but it is reasonably precise -- enough that it shouldn't be half a minute off.
One interesting hack for event troubleshooting is to throw a warning from within the event. Since there is no client to which the warning can be sent, the warning is written to the MySQL error log. This should work in MySQL 5.5 and up:
DELIMITER $$
DROP EVENT IF EXISTS run_event $$
CREATE DEFINER=`root`#`%`
EVENT `run_event`
ON SCHEDULE EVERY 5 MINUTE STARTS '2016-04-06 00:00:00'
ON COMPLETION NOT PRESERVE ENABLE
DO
BEGIN
SIGNAL SQLSTATE '01000' SET MESSAGE_TEXT = 'run_event started';
CALL my_procedure;
SIGNAL SQLSTATE '01000' SET MESSAGE_TEXT = 'run_event finished';
END $$
It's been a while since I used this, but I believe the warnings will be written to the error log immediately, and not buffered until the event is finished.
I am using mysql workbench6.3.7. I used event scheduler to execute the query everyday morning 9 o'clock I have used the following query
delimiter $$
create event eventtable
on schedule every '1' day
starts '2016-11-25 16:00:00'
do
begin
<statement>
end;
$$;
but it's working only one day it's not working daily.What am I missing??.Should i have to execute the query daily? Should I have to on the global scheduler daily? Please help me with this.
Thank you,
Jen
i have created following event for myself,That's working fine.look at this
CREATE DEFINER=`developer`#`%` EVENT `event_final_report_horn` ON SCHEDULE EVERY 2 MINUTE STARTS '2016-09-20 12:00:00' ON COMPLETION NOT PRESERVE ENABLE COMMENT 'Event generates horn final reports after completion of testing' DO BEGIN
if current_Time>='04:00:00' then
CALL hero_final_report_process_horn_data();
end if;
end
I have created an event in MySQL using this query:
delimiter $$
create event update_usability_score
on schedule every 1 day
starts '2013-01-07 18:22:00'
do
begin
insert into table_name(pk_id,name) values(1,"testing");
update table table_name set name = 'Not testing' where name like '%testing%';
end//
delimiter ;
When I run this for 1st time it's working fine and not showing any error. As I queried this event will run every day. But it is not running everyday.
When I check with this:
select name, last_executed from mysql.event;
it is showing the start date. Means it is not running everyday.
How to run this event everyday? Anything I have missed in the query?
Please help to solve this problem, thanks in advance.
You need to set ON COMPLETION PRESERVE option:
CREATE EVENT update_usability_score
ON SCHEDULE EVERY 1 DAY
STARTS '2013-01-07 18:22:00'
ON COMPLETION PRESERVE
DO
BEGIN
...
END
From the event documentation:
Normally, once an event has expired, it is immediately dropped. You can override this behavior by specifying ON COMPLETION PRESERVE. Using ON COMPLETION NOT PRESERVE merely makes the default nonpersistent behavior explicit.
This particular event would fail because the very first query in the event would fail if you would run it second time as id 1 would be already in the database.
I have this stored procedure. How can I run this for example with intervals of 5 seconds? Like a routine for eliminate data with a time-stamp older than one day?
DROP PROCEDURE IF EXISTS `delete_rows_links`
GO
CREATE PROCEDURE delete_rows_links
BEGIN
DELETE activation_link
FROM activation_link_password_reset
WHERE TIMESTAMPDIFF(DAY, `time`, NOW()) < 1 ;
END
GO
You can use mysql scheduler to run it each 5 seconds. You can find samples at http://dev.mysql.com/doc/refman/5.1/en/create-event.html
Never used it but I hope this would work:
CREATE EVENT myevent
ON SCHEDULE EVERY 5 SECOND
DO
CALL delete_rows_links();
I used this query and it worked for me:
CREATE EVENT `exec`
ON SCHEDULE EVERY 5 SECOND
STARTS '2013-02-10 00:00:00'
ENDS '2015-02-28 00:00:00'
ON COMPLETION NOT PRESERVE ENABLE
DO
call delete_rows_links();
In order to create a cronjob, follow these steps:
run this command : SET GLOBAL event_scheduler = ON;
If ERROR 1229 (HY000): Variable 'event_scheduler' is a GLOBAL
variable and should be set with SET GLOBAL:
mportant
It is possible to set the Event Scheduler to DISABLED only at server startup. If event_scheduler is ON or OFF, you cannot set it to DISABLED at runtime. Also, if the Event Scheduler is set to DISABLED at startup, you cannot change the value of event_scheduler at runtime.
To disable the event scheduler, use one of the following two methods:
As a command-line option when starting the server:
--event-scheduler=DISABLED
In the server configuration file (my.cnf, or my.ini on Windows systems):
include the line where it will be read by the server (for example, in a [mysqld] section):
event_scheduler=DISABLED
Read MySQL documentation for more information.
DROP EVENT IF EXISTS EVENT_NAME;
CREATE EVENT EVENT_NAME
ON SCHEDULE EVERY 10 SECOND/minute/hour
DO
CALL PROCEDURE_NAME();
If you're open to out-of-the-DB solution: You could set up a cron job that runs a script that will itself call the procedure.
