I am trying to create a trigger to insert a new row conditionally based on an insert on another table...I can't seem to nail the syntax. Here is what I have thus far:
DELIMETER $$
CREATE TRIGGER overPricedCar
AFTER INSERT ON cars
FOR EACH ROW
BEGIN
IF (new.sellPrice > '80000' )THEN
INSERT INTO listings VALUES(new.carName,'GOLD','0',' ');
END IF;
END$$
DELIMETER ;
For some reason I keep getting an error, they syntax seems to be OK, I'm not sure where I may have gone wrong.
EDIT
After correcting the typo, the trigger 'works'.
I have added a comment to be output when the trigger happens. I have tested it, and the output message gets printed to the screen but the trigger does not actually complete the inserts:
DELIMITER $$
CREATE TRIGGER overPricedCar
BEFORE INSERT ON cars
FOR EACH ROW
BEGIN
IF (new.sellPrice > '80000' )THEN
INSERT INTO listings VALUES(new.carName,'GOLD','0',' ');
SIGNAL SQLSTATE '45000' SET MESSAGE_TEXT = "New Gold car!"; // this line throws it off
END IF;
END$$
DELIMITER ;
Where can I place the messages I want to be printed to the screen when this trigger runs?
