我希望我的活动每天00:20举行。我对时间安排感到困惑。我应该使用第一个选项还是第二个选项?
选项1
CREATE EVENT my_event
ON SCHEDULE
EVERY 1 DAY
STARTS '2014-04-30 00:20:00' ON COMPLETION PRESERVE ENABLE
DO
# My query
选项2
CREATE EVENT my_event
ON SCHEDULE
AT ('2014-04-30 00:20:00'+ INTERVAL 1 DAY) ON COMPLETION PRESERVE ENABLE
DO
# My query
ON COMPLETION PRESERVE ENABLE
意思?
