Trigger action overview
A trigger action is a simple SQL statement.
For example:
CREATE TRIGGER . . .
DELETE FROM flightavailability
WHERE flight_id IN (SELECT flight_id FROM flightavailability
WHERE YEAR(flight_date) < 2005);)
A trigger action does have some limitations, though; for example, it cannot
contain dynamic parameters or alter the table on which the trigger is defined.
See "TriggerAction" in the Derby Reference Manual for
details.
