I have to do two triggers, first one, after insert in test1 table, to insert in test2 table another row. All right, the problem is that i have to do same trigger in reverse form, after insert row in test2 table, insert new row on test1. I know that trigger can't insert in a table when a trigger is firing, but i need resolve this. I don't have a lot experience with triggers, i hope that this could be resolved.
DELIMITER $$ CREATE TRIGGER `ai_test1_test2` AFTER INSERT ON `test1`
FOR EACH ROW
BEGIN INSERT INTO test2 (vtest2) VALUES (new.vtest1)
END$$
DELIMITER ;
Bidirectional trigger:
DELIMITER $$ CREATE TRIGGER `ai_test2_test1` AFTER INSERT ON `test2`
FOR EACH ROW
BEGIN INSERT INTO test1 (vtest1) VALUES (new.vtest2)
END$$
DELIMITER ;
Thanks.
Edit:
The infinite loop can't be resolved. Triggers can't be bidirectional... I think that i must be use a PROCEDURE...

There is a posible solution for the problem:
DELIMITER $$ CREATE TRIGGER `ai_test1_test2` AFTER INSERT ON `test1`
FOR EACH ROW
BEGIN
IF NOT EXISTS( SELECT vtest2 FROM test2 WHERE vtest2 = new.vtest1 ) THEN
INSERT INTO test2 (vtest2) VALUES (new.vtest1)
END IF;
END$$
DELIMITER ;
DELIMITER $$ CREATE TRIGGER `ai_test2_test1` AFTER INSERT ON `test1`
FOR EACH ROW
BEGIN
IF NOT EXISTS( SELECT vtest1 FROM test1 WHERE vtest1 = new.vtest2 ) THEN
INSERT INTO test1 (vtest1) VALUES (new.vtest2)
END IF;
END$$

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 get an error trying to create a trigger in MySQL using the ExtractValue function:
CREATE TRIGGER biblioitems_after_marcxml_update
AFTER UPDATE ON biblioitems
FOR EACH ROW BEGIN
INSERT IGNORE INTO X_BIBLIONUMBER_BIBID VALUES (NEW.biblionumber, EXTRACTVALUE(NEW.marcxml, '//controlfield[#tag="001"]' ));
END
Any ideas what is going wrong here are very welcome.
Are you using DELIMITER?
Try:
DELIMITER //
CREATE TRIGGER biblioitems_after_marcxml_update AFTER UPDATE ON biblioitems
FOR EACH ROW
BEGIN
INSERT IGNORE INTO X_BIBLIONUMBER_BIBID
VALUES
(NEW.biblionumber, EXTRACTVALUE(NEW.marcxml, '//controlfield[#tag="001"]'));
END//
DELIMITER ;
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);
I'm trying to create a trigger with a definer and some simple action inside, but doesn't get accepted by mysql and freezes the phpMyadmin without giving an error. Can someone help me to find the mistake
delimiter //
CREATE TRIGGER log_items after insert on Profiles
FOR EACH ROW
IF USER() LIKE 'admin#%' THEN
begin
INSERT INTO ItemsLog (`record_id`, `record_time`) VALUES (NEW.id, now());
end; //
END IF;
delimiter ;
Here is full trigger code that is accepted by phpmyadmin. It was generated when using the sql ide: SQLyog.
DELIMITER //
USE `testmysql`//
DROP TRIGGER /*!50032 IF EXISTS */ `log_items`//
CREATE
DEFINER = 'test'#'localhost'
TRIGGER `log_items` AFTER INSERT ON `profiles`
FOR EACH ROW IF USER() LIKE 'admin#%' THEN
BEGIN
INSERT INTO ItemsLog (`record_id`, `record_time`) VALUES (NEW.id, NOW());
END;
END IF;
