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'
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 ;
This shows no errors in mysql workbbench

SQL query: Documentation
CREATE TRIGGER `dis_out_of_stock` AFTER UPDATE ON `ps_stock_available`

Here is my code:
CREATE TRIGGER dis_out_of_stock AFTER UPDATE ON ps_stock_available
FOR EACH ROW
begin
UPDATE ps_product_shop SET active=0 WHERE id_product IN (SELECT id_product FROM ps_stock_available WHERE quantity=0);
UPDATE ps_product_shop SET active=1 WHERE id_product IN (SELECT id_product FROM ps_stock_available WHERE quantity>0);
end
Thanks and have a nice day.
You need to redefine DELIMITER to something else other than ;, for eg: $$
Also, check if the trigger already exists or not, using DROP TRIGGER IF EXISTS.
At the end, redefine the DELIMITER to ;
Try:
DELIMITER $$
DROP TRIGGER IF EXISTS dis_out_of_stock $$
CREATE TRIGGER dis_out_of_stock
AFTER UPDATE ON ps_stock_available
FOR EACH ROW begin
UPDATE ps_product_shop
SET active=0
WHERE id_product IN (SELECT id_product
FROM ps_stock_available
WHERE quantity = 0);
END $$
DELIMITER ;
You should not be attempting to update the entire ps_product_shop table. Instead, just look at the record that was just modified:
DELIMTER $$
CREATE TRIGGER `dis_out_of_stock` AFTER UPDATE ON `ps_stock_available`
FOR EACH ROW
BEGIN
UPDATE ps_product_shop ps
SET active = 0
WHERE ps.id_product = new.id_product and new.quantity = 0;
END;
DELIMITER ;
I am trying to create mysql trigger but getting an error

Here is my sql script

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

I have three tables, when data is inserted into third table, I am checked whether newly inserted row has field value in table1. If value exists then I am moving the same row from table3 to table2. My code is like below, But I am getting error while executing this
DELIMITER $$
CREATE TRIGGER onRosterAdd
AFTER INSERT ON yet_tobe
FOR EACH ROW
BEGIN
SELECT CASE WHEN (SELECT 1 FROM users WHERE NEW.jid = (users.username + "_1")) > 0
THEN
INSERT INTO rusers SELECT * FROM yet_tobe WHERE yet_tobe.id = NEW.id;
DELETE FROM yet_tobe where yet_tobe.id = NEW.id;
END
END$$
DELIMITER ;
And here is the error
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 'INTO rusers SELECT * FROM yet_tobe WHERE yet_tobe.id = NEW.id;
How can I fix this.
Try it like this:
DELIMITER $$
CREATE TRIGGER onRosterAdd
BEFORE INSERT ON yet_tobe
FOR EACH ROW
BEGIN
IF (SELECT 1 FROM users WHERE CONCAT(username,"_1")=NEW.jid)>0
THEN
INSERT INTO rusers SELECT * FROM yet_tobe WHERE yet_tobe.id = NEW.id;
DELETE FROM yet_tobe where yet_tobe.id = NEW.id;
END IF;
END$$
DELIMITER ;
Here's a working fiddle

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')

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;

Hello currently my trigger updates on table update, and I need to change this to only fire when specific column changes.
code:
create trigger money after update on things
for each row
begin
UPDATE `current` c
INNER JOIN things t ON c.id2 = t.id2
INNER JOIN dude_base d ON d.id1 = c.is1
SET c.`curr_cash` = t.thing_cost * d.salary / 100;
end;
$$
And I need to change so it will turn on, when there is update on "thing_cost" from things.
#edit
I have to update that curr_cash and things cost are totaly different values, I cannot compare them, they will always be different.
When I used
if NEW.things_cost <> OLD.things_cost
I get following 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 10
#edit

end if;
