sql - How to tell if a mySql event succeeded or not? -


i have around 5 mysql events autorun 15 minutes after each done.

they update table sum() of votes, starting @ 00:00.

is there way tell if event failed? if failed other events need not run. failed mean internally (sql gone wild) or didn't execute @ all.

one way thought of doing this, have event called stored procedure or function on success, in turn call others. possible?

you may try use exit handler:

drop event if exists `mydb`.`myevent`;  create event if not exists `mydb`.`myevent` on schedule     every 15 minute comment 'some comment' begin declare exit handler sqlexception, sqlwarning     begin     -- 1. flag something, should tested in chained events     --    if should skipped. i.e.:      --    insert `mydb`.`eventtable` (`event`, `failed`, `when`)     --    values ('myevent', true, now());      --    or      --    update     --        `mydb`.`eventtable`     --    set     --        `failed` = true,     --        `when`   = now()     --        --        `event` = 'myevent';      -- 2. quit.     end;  -- something, may produce sqlexception or sqlwarning... end;
