I try to create trigger in MySql but get the 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 'DELIMITER' at line 1
DELIMITER $$
CREATE TRIGGER library_update
AFTER UPDATE ON wq6vt_vehiclemanager_vehicles
FOR EACH ROW
BEGIN
INSERT IGNORE INTO wq6vt_vehiclemanager_library (maker, model) VALUES(NEW.maker, NEW.vmodel);
INSERT INTO wq6vt_vehiclemanager_library_data (co2_class)
SELECT co2_class FROM wq6vt_vehiclemanager_vehicles
WHERE maker = NEW.maker AND vmodel = NEW.vmodel;
END $$
DELIMITER;
The first query in the trigger do not lead to errors, but second one does. There is some problem with SELECT inside of INSERT ...I think so
there should be a space between the keyword and the symbol,
DELIMITER ;
-- ^ space in between here

CREATE EVENT demo

You need to change the delimiter when you run DDL statements like this. MySQL is interpreting your semicolon as the end of your CREATE EVENT query, not as a delimiter within it.
Try this:
DELIMITER $$
CREATE EVENT demo
ON SCHEDULE
EVERY 2 SECOND
DO BEGIN
update alarm set is_on=1;
END $$
DELIMITER ;
I'm trying to create a trigger in MySQL using phpMyAdmin, but I'm getting and error and I can't detect the mistake. The main idea its to create a row in the tables stuff and config when a new user is insered.
The code:
CREATE TRIGGER create_stuff_and_config
AFTER INSERT ON user
FOR EACH ROW
BEGIN
insert into stuff(user_id) values (NEW.user_id);
insert into config(user_id) values(NEW.user_id);
END;
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
I've checked the MySQL doc but I see like I'm doing it well...
I've tried too: INSERT INTO stuff SET user_id = NEW.user_id;
Thank you!
Okay, the solution is to add delimiters...
DELIMITER //
CREATE TRIGGER create_stuff_and_config
AFTER INSERT ON user
FOR EACH ROW
BEGIN
insert into stuff(user_id) values (NEW.user_id);
insert into config(user_id) values(NEW.user_id);
END; //
DELIMITER ;
m writing following lines for creating a trigger:
create trigger notify after insert on applications
for each row
begin
insert into notifications SET sno=1;
end;
but everytime i get following 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 '' at line 4
line 4 is - insert into notifications SET sno=1
MySQL is confused about the delimiters. It thinks the first ; is the end of the TRIGGER declaration (which it is not). Use delimiter to change it temporarily, and later to change it back:
delimiter |
create trigger notify after insert on applications
for each row
begin
insert into notifications (sno) values (1);
end;
|
delimiter ;
More in the documentation.
I am trying to set up a trigger on a table to copy the contents of a row into another table.
I have the following:
CREATE TRIGGER story_deleted BEFORE DELETE ON stories
FOR EACH ROW BEGIN
INSERT INTO stories_backup SET story_id = OLD.story_id;
END;
This returns the following error though:
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 3
I can't work out where I'm going wrong with this. Any ideas?
Try changing the delimiter
DELIMITER $$
CREATE TRIGGER story_deleted BEFORE DELETE ON stories
FOR EACH ROW
BEGIN
INSERT INTO stories_backup SET story_id = OLD.story_id;
END $$
DELIMITER ;
and as far as your privileges go, run this query
SHOW GRANTS;
If SUPER is not there, you could
request your DBA to add that privilege for you
have your DBA create the trigger for you
I tried writing this small trigger in MySQL,
CREATE TRIGGER `leg` BEFORE INSERT ON `bckoff`
FOR EACH ROW BEGIN
INSERT INTO `bckoff` SET `step`=1;
END;
after which I get this error.. I'm a newbie to MySQL.. so please help me out here..
#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 3
Even after you fix this error - you'll get another one: you cannot modify the table that your trigger was created at.
Btw, this is how you should create this trigger:
delimiter |
CREATE TRIGGER `leg` BEFORE INSERT ON `bckoff`
FOR EACH ROW BEGIN
INSERT INTO `bckoff` SET `step`=1;
END;
|
delimiter ;
