Basically, there are two kinds of events for which we need to specify the schedule −
One-time event
One-time event means it will be executed only once on a particular schedule. If we want to create a one-time event then we need to put the following syntax after ON SCHEDULE clause −
AT Timestamp[+INTERVAL]
Recurring events
Recurring event means that it will be executed after regular time of interval. If we want to create a recurring event then we need to put the following syntax after ON SCHEDULE clause −
EVERY interval STARTS timestamp [+INTERVAL] ENDS timestamp [+INTERVAL]
