Any event handler can be manually triggered, as well as executed because of a schedule or system event. You may find it useful to manually trigger events during development of event handlers, and also, for certain events, in production environments. For example, you may have a monthly sales report scheduled, but from time to time you may want to obtain a sales report for a reason other than the end of the month.
See”Triggering an event handler” in SQL Anywhere Server - SQL Usage.
