I've tried to create trigger for each new post
here is my code
CREATE TRIGGER insertprod AFTER INSERT ON post
FOR EACH ROW
BEGIN
INSERT INTO attributes SET attrtext = 'sometext', post_id = NEW.id;
END;
I'm getting this error
You probably just need a delimiter:
DELIMITER $$
CREATE TRIGGER insertprod AFTER INSERT ON post
FOR EACH ROW
BEGIN
INSERT INTO attributes SET attrtext = 'sometext', post_id = NEW.id;
END;
$$
DELIMITER ;
However, you are also using a non-standard form of INSERT. I would suggest:
DELIMITER $$
CREATE TRIGGER insertprod AFTER INSERT ON post
FOR EACH ROW
BEGIN
INSERT INTO attributes(attrtext, post_id)
VALUES('sometext', NEW.id);
END;
$$
DELIMITER ;
The parser is confused by the ; that terminates the statement inside the trigger's BEGIN...END block. You need to use a DELIMITER statement to define a new delimiter, which you can then use to end the CREATE TRIGGER statement.
Your INSERT command is wrong. It should have been
INSERT INTO attributes (attrtext, post_id) VALUES ('sometext', NEW.id);

Hi guys I am trying to make some triggers to update in one table after insert in other table but it reports me an error. Two tables have the same fields and with the same name.
Here is the code.
DELIMITER //
CREATE TRIGGER Insertar_Bares_Private AFTER INSERT ON Bares
FOR EACH ROW
BEGIN
INSERT INTO Bares_Private (nombrebar, direccion) VALUES (new.nombrebar, new.direccion);
END//
CREATE TRIGGER Insertar_Categorias_Private AFTER INSERT ON Categorias
FOR EACH ROW
BEGIN
INSERT INTO Categorias_Private (nombrecategoria) VALUES (new.nombrecategoria);
END//
CREATE TRIGGER Insertar_Productos_Private AFTER INSERT ON Productos
FOR EACH ROW
BEGIN
INSERT INTO Productos_Private (nombreproducto, idcategoria, descripcion, precio, imagen) VALUES (new.nombreproducto, new.idcategoria, new.descripcion, new.precio, new.imagen);
END//
-- Triggers al actualizar
CREATE TRIGGER Actualizar_Usuarios_Private AFTER UPDATE on Usuarios
for each ROW
BEGIN
UPDATE Usuarios_Private
SET nombreusuario=new.nombreusuario, contrasenia=new.contrasenia, email=new.email, telefono=new.telefono
where idusuario=new.idusuario;
END//
CREATE TRIGGER Actualizar_Bares_Private AFTER UPDATE on Bares
for each ROW
BEGIN
UPDATE Bares_Private
SET nombrebar=new.nombrebar, direccion=new.direccion
where idbar=new.idbar;
END//
CREATE TRIGGER Actualizar_Categorias_Private AFTER UPDATE on Categorias
for each ROW
BEGIN
UPDATE Categorias_Private
SET nombrecategoria=new.nombrecategoria
where idcategoria=new.idcategoria;
END//
CREATE TRIGGER Actualizar_Productos_Private AFTER UPDATE on Productos
for each ROW
BEGIN
UPDATE Productos_Private
SET nombreproducto=new.nombreproducto, idcategoria=new.idcategoria, descripcion=new.descripcion, precio=new.precio, imagen=new.imagen
where idproducto=new.idproducto;
END//
DELIMITER ;
And here is the error reported.
#1235 - This version of MySQL doesn't yet support 'multiple triggers with the same action time and event for one table'
Thank you in advice.
Remove the ; from all the END; and apply the delimiter END// will solve your problem.
Since you already placed the proper ; for the INSERT/UPDATE statement, so no need to place it again in the END;.
You only need to change the delimiter before defining a trigger if the trigger contains more than one query. This is because you need to use the default delimiter ; in this case to separate the queries within the trigger, but the MySQL client will incorrectly think you mean to terminate the trigger definition here. This also requires you to use BEGIN ... END around the block of queries in the trigger.
DELIMITER //
CREATE TRIGGER Insertar_Usuarios_Private AFTER INSERT ON Usuarios
FOR EACH ROW
BEGIN
INSERT INTO Usuarios_Private (nombreusuario, contrasenia, email,telefono) VALUES (new.nombreusuario, new.contrasenia, new.email, new.telefono);
END//
CREATE TRIGGER Insertar_Bares_Private AFTER INSERT ON Bares
FOR EACH ROW
BEGIN
INSERT INTO Bares_Private (nombrebar, direccion) VALUES (new.nombrebar, new.direccion);
END//
-- and so on ...
DELIMITER ;
However, your triggers each only contain one query. Therefore you can dispense with the delimiter and the BEGIN ... END block entirely.
CREATE TRIGGER Insertar_Usuarios_Private AFTER INSERT ON Usuarios
FOR EACH ROW
INSERT INTO Usuarios_Private (nombreusuario, contrasenia, email,telefono) VALUES (new.nombreusuario, new.contrasenia, new.email, new.telefono);
CREATE TRIGGER Insertar_Bares_Private AFTER INSERT ON Bares
FOR EACH ROW
INSERT INTO Bares_Private (nombrebar, direccion) VALUES (new.nombrebar, new.direccion);
-- and so on ...
I have table "book" and "store_order" have relation
I want to make trigger(but it contain error):
DELIMITER $$
CREATE TRIGGER t1
before delete ON store_order
FOR EACH ROW
BEGIN
update book set number = number + NEW.quantity where ISBN = NEW.ISBN;
END
$$
DELIMITER ;
DELIMITER $$
CREATE
TRIGGER t2 AFTER delete
ON library.store_order
FOR EACH ROW BEGIN
update library.book
set library.book.number = (library.book.number + OLD.quantity)
where library.book.ISBN = OLD.ISBN;
END$$
DELIMITER ;
Use OLD instead of NEW when you want to get the deleted object.
for an example of my case. I'm getting the id of the newly added role by calling
NEW.id
and getting the same field's value while deleting by calling
OLD.id
Example:
DELIMITER $$
CREATE TRIGGER after_insert_role
AFTER INSERT ON role FOR EACH ROW
BEGIN
INSERT INTO `sync_mapping`
(`operation_type`, `table_name`, `oid`, `end_point`)
VALUES
('insert', 'role', NEW.id, 'new/role');
END $$
DELIMITER $$
CREATE TRIGGER after_delete_role
AFTER DELETE ON role FOR EACH ROW
BEGIN
INSERT INTO `sync_mapping` (`operation_type`, `table_name`, `oid`, `end_point`) VALUES
('delete', 'role', OLD.id, 'delete/role');
END $$
Whenever we are deleting the data
USE
OLD. instead of NEW.
CREATE TRIGGER user_history_delete AFTER DELETE ON user FOR EACH ROW
INSERT INTO user_history(action , name )
VALUES ("Delete" , OLD.name );
I have created the following trigger in mysql:
DELIMITER $$
CREATE TRIGGER `some_trigger` AFTER INSERT ON db1.table
FOR EACH ROW
BEGIN
IF NEW.userid = 'certain_id' THEN
INSERT INTO db2.table
SET
value1 = NEW.value,
value2 = NEW.value;
END IF;
END $$
DELIMITER ;
The above statement works if I remove the if statement. Additionally no syntax errors are encountered when this trigger is added to the db. Any idea what is wrong with the if statement that is not allowing it to insert entries with value 'certain_id' in column userid when added to db1.table??
Try this it should work..
DELIMITER $$
CREATE TRIGGER `some_trigger` AFTER INSERT ON `db1`.`table`
FOR EACH ROW
BEGIN
IF (NEW.userid = 'certain_id') THEN
INSERT INTO `db2`.`table` (value1, value2)
VALUES (NEW.value1,NEW.value2);
END IF;
END $$
DELIMITER ;
Here is a trigger i created and i want to compare new.utype with employee as given below but dont know the actual way to compare it in mysql .. how can i achieve this and also please tell if condition syntax is correct or not
delimiter $$
CREATE TRIGGER insdetail_tomaster
AFTER INSERT ON tempdetail
FOR EACH ROW BEGIN
IF(new.utype =='employee') THEN
INSERT INTO master_employee values(new.field1,new.filed2);
ELSE
INSERT INTO master_manager values(new.field1,new.fiel2);
END $$
DELIMITER ;
Use "like" key word as below
IF new.utype like 'employee'
Entire trigger looks like this
delimiter $$
CREATE TRIGGER insdetail_tomaster
AFTER INSERT ON tempdetail
FOR EACH ROW BEGIN
IF new.utype like 'employee' THEN
INSERT INTO master_employee values(new.field1,new.filed2);
ELSE
INSERT INTO master_manager values(new.field1,new.fiel2);
END $$
DELIMITER ;
I assumed trigger you wrote other than the string comparison is correct
Thanks
You need to use single = instead of ==
IF new.utype = 'employee'
DELIMITER $$
CREATE TRIGGER insdetail_tomaster
AFTER INSERT ON tempdetail
FOR EACH ROW BEGIN
IF new.utype = 'employee' THEN
INSERT INTO master_employee values(new.field1,new.filed2);
ELSE
INSERT INTO master_manager values(new.field1,new.fiel2);
END $$
DELIMITER ;
You can also use <> for comparing not equal value.
IF new.utype <> 'employee'
DELIMITER $$
CREATE TRIGGER insdetail_tomaster
AFTER INSERT ON tempdetail
FOR EACH ROW BEGIN
IF new.utype <> 'employee' THEN
INSERT INTO master_employee values(new.field1,new.filed2);
ELSE
INSERT INTO master_manager values(new.field1,new.fiel2);
END $$
DELIMITER ;
I would like to check if a record is being created with a user id, if not then generate one. I can't figure out what I'm doing wrong?
delimiter $$
DROP TRIGGER IF EXISTS init_uuid_users;
CREATE TRIGGER init_uuid_users BEFORE INSERT ON `users`
FOR EACH ROW BEGIN
IF (NEW.username IS NULL) THEN
SET NEW.username = UUID();
END IF;
END;
$$
delimiter ;
DROP TRIGGER IF EXISTS init_uuid_users;
put it before delimiter.
And remove ; after END.
