I'm trying to change a value conditionally on my trigger, but I've got an error.
My trigger is:
CREATE TRIGGER `defineBase` BEFORE INSERT ON `perguntas`
FOR EACH ROW
BEGIN
IF NEW.per_base = 0 THEN
SET NEW.per_base = (SELECT per_id FROM perguntas ORDER BY per_id DESC LIMIT 1) + 1;
END IF;
END;
but doesn't work.
You need to change the delimiter to something else than ;. Otherwise the trigger definition stops at the first ;
delimiter |
CREATE TRIGGER `defineBase` BEFORE INSERT ON `perguntas`
FOR EACH ROW
BEGIN
IF NEW.per_base = 0 THEN
SET NEW.per_base = (SELECT per_id FROM perguntas ORDER BY per_id DESC LIMIT 1) + 1;
END IF;
END
|
delimiter ;
I also have the same problem. My SQL code before is just like this (without delimiter):
CREATE TRIGGER update_created_time BEFORE INSERT
ON contact FOR EACH ROW
BEGIN
SET NEW.created=NOW();
END
Then, after i add the following DELIMITER // and close it with the same //
DELIMITER //
CREATE TRIGGER update_created_time BEFORE INSERT
ON contact FOR EACH ROW
BEGIN
SET NEW.created=NOW();
END //
It works. I hope it can help someone in the future...
