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 ;

Trying to create a simple trigger that after a table update, it checks if a count (InvalidLogins) is over 4, and if so, sets the field 'LockedOut' to 1. Below is how I am attempting to create the trigger, this is my first trigger for MySQL though and I can't get it to work.
CREATE TRIGGER update_user_lockout after update ON members
FOR EACH ROW SET LockedOut = 1 where invalidLogins < 4
The error that MySQL returns is:
Error Code: 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 '.LockedOut = 1 where invalidLogins < 4' at line 2
delimiter |
CREATE TRIGGER update_user_lockout before update ON members
FOR EACH ROW
IF NEW.invalidLogins < 4 THEN
SET NEW.LockedOut = 1;
END IF;
END
|
delimiter ;
The current record can be referenced with NEW
Choose another delimiter than ;. Otherwise the trigger definition will end at the first ; which is too early
Use a before trigger to change values before updating
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 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
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 have a very large file that creates triggers that I auto generated. However I'm not able to get passed line 3.
Php version 5.3.2
Mysql Version 14.14 Distrib 5.1.41
Here are the first few lines:
1 delimiter $$
2 -- CompanyTitleHolder
3 -- Create INSERT event for CompanyTitleHolder
4 CREATE OR REPLACE TRIGGER trigger_insert_CompanyTitleHolder AFTER INSERT ON CompanyTitleHolder
5 FOR EACH ROW
6 BEGIN
7
8 IF(NEW.CompanyTitleHolderID <> '') OR (NEW.CompanyTitleHolderID IS NOT NULL) THEN
9 CALL add_Audit (#UserName, "CompanyTitleHolder", "CompanyTitleHolderID", "--new record--", NEW.CompanyTitleHolderID);
10 END IF;
11 -- This goes on for quite a while
?? END;$$
?? delimiter ;
And this is the error:
/* SQL 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 'TRIGGER trigger_insert_CompanyTitleHolder AFTER INSERT ON CompanyTitleHolder F' at line 3 */
I'm trying to do an audit table using this method and code as my base
MySQL doesn't support OR REPLACE: http://dev.mysql.com/doc/refman/5.6/en/create-trigger.html
CREATE OR REPLACE doesn't seem to work in MySQL, it's an Old Bug. You'll have to do a DROP TRIGGER IF EXISTS before your CREATE TRIGGER statement.
You can't CREATE OR REPLACE.
Try:
DROP TRIGGER IF EXISTS trigger_insert_CompanyTitleHolder;
CREATE TRIGGER trigger_insert_CompanyTitleHolder AFTER INSERT ON CompanyTitleHolder
