You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'if (new.status = '2' or new.status ='3')
then
delete from ind_user_events wh' at line 7

Change
SET #user_id=OLD.id
to
SET #user_id=OLD.id;
^
You actually don't even need this variable. So ditch that line and try
...
IF (NEW.STATUS = '2' OR NEW.STATUS ='3') THEN
DELETE FROM ind_user_events WHERE user_id = OLD.id;
DELETE FROM ind_user_mobile WHERE user_id = OLD.id;

Mysql trigger creation bad syntax

I'm trying to create a SQL Trigger, but i receive always an error message, i want to check on update and insert operation if value called status is not higher than 1 and not lower than 0.
CREATE TRIGGER tr_ins_cert_login
BEFORE UPDATE ON cert_login
FOR EACH ROW
BEGIN
DECLARE errorMessage VARCHAR(255);
SET errorMessage('Invalid Status Value.');
IF new.status <> 0 AND new.status <> 1 THEN
SET MESSAGE_TEXT = errorMessage;
END IF;
END
When i try to run the commands it returns error.
I'm using MySql.
The error:
#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 5
Any hint?
Message_text should be part of signal sqlstate following syntaxes on my box
drop trigger if exists t;
delimiter $$
CREATE TRIGGER t
BEFORE UPDATE ON cert_login
FOR EACH ROW
BEGIN
DECLARE errorMessage VARCHAR(255);
SET errorMessage = ('Invalid Status Value.');
IF new.status <> 0 AND new.status <> 1 THEN
SIGNAL SQLSTATE '01000'
SET MESSAGE_TEXT = errorMessage;
END IF;
END $$

Mysql trigger if statement update second table

I am trying to create a mysql trigger. This is what I am trying to create, but somehow it tells me that: "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'A
FOR EACH ROW".
What Am I doing wrong here? I have tried to naming them differently, but it does not seem to work.
delimiter //
CREATE TRIGGER stock_update BEFORE UPDATE ON `stock` A
FOR EACH ROW
BEGIN
IF NEW.`quantity` < 1 THEN //belongs to alias A
UPDATE `ps_product` B
SET B.`visibility` = 'none';
WHERE id_product = OLD.id_product //Should be the id_product of A alias
ELSEIF NEW.quantity > 0 THEN
UPDATE `ps_product` C
SET C.`visibility` = 'both';
WHERE id_product = OLD.id_product //Should be the id_product of A alias
END IF;
END;//
delimiter ;
Try this one
delimiter //
CREATE TRIGGER stock_update BEFORE UPDATE ON `stock`
FOR EACH ROW
BEGIN
IF NEW.`quantity` < 1 THEN #belongs to alias A
UPDATE `ps_product` B
SET B.`visibility` = 'none'

ELSEIF NEW.quantity > 0 THEN
UPDATE `ps_product` C

Remove space between ELSE and IF. It should be ELSEIF as below.
