Home -> Community -> Usenet -> c.d.o.server -> trigger statement:
Quick question. This trigger works fine (it just sets a themepark rides
status as closed when an accident has been inserted into the accident
table):
CREATE TRIGGER closeride
AFTER INSERT ON Accident
REFERENCING NEW AS newRow
FOR EACH ROW
BEGIN
update Ride set Ride.status = 'closed' where Ride.Ridename =
:newRow.Ridename;
END closeride;
Now I want to make a variation on this where if the accident table returns more than 3 rows for a given ride then the ride status is set to closed. This is my attempt (bellow). Could someone take a look at it? Its the same as the one above except for the WHEN
CREATE TRIGGER toomanyaccidents
AFTER INSERT ON Accident
REFERENCING NEW AS newRow
FOR EACH ROW
WHEN((select * from accident where Ridename = :new.Ridename)> 2)
BEGIN
update Ride set Ride.status = 'closed' where Ride.Ridename =
:newRow.Ridename;
END closeride;
