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 have a table which contains columns as "barkoda1,barkoda2,barkoda3,#pdfa1,#pdfa2,#pdfa3", what i'm trying to do is when a record assigned to barkoda1 copy same record to #pdfa1,for example if barkoda1 defined as "1234567890" #pdfa1 should be "1234567890.pdf".
i tried to create a trigger for it, but failed;
DELIMITER //
CREATE TRIGGER pdfdeneme AFTER INSERT
ON finyeb_ba_2369_bio_for_2__r_d_
FOR EACH ROW
BEGIN
UPDATE finyeb_ba_2369_bio_for_2__r_d_ SET `#pdfa1`=NEW.barkoda1;
END//
DELIMITER ;
when i create this trigger,it doesn't return any error but when i add record to table mysql returns "it is already used by statement which invoked this stored function/trigger".
also tried this way
DELIMITER //
CREATE TRIGGER pdfdeneme BEFORE INSERT
ON finyeb_ba_2369_bio_for_2__r_d_
FOR EACH ROW
BEGIN
INSERT INTO finyeb_ba_2369_bio_for_2__r_d_(`#pdfa1`) VALUES(NEW.barkoda1);
END//
DELIMITER ;
But same error happened, what am i doing wrong here?
You need a BEFORE INSERT TRIGGER
And then only use the SET Clause
DELIMITER //
CREATE TRIGGER pdfdeneme BEFORE INSERT
ON finyeb_ba_2369_bio_for_2__r_d_
FOR EACH ROW
BEGIN
SET NEW.`#pdfa1` = CONCAT(NEW.barkoda1,'.pdf');
END//
DELIMITER ;
But your column name is a bad choice, it leads on the first glance to false conclusions.
I am creating trigger for after insert but I am getting error.
DELIMITER //
CREATE TRIGGER ParticleTableInsert

I am new to mysql, sonot understanding what is wrong with my query. Please help.
DELIMITER //

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'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);
ALTER TABLE aspnet_Paths ALTER PathId SET DEFAULT UUID();
I've ran a converter program on "generate" scripts from a SQL Server database.
I seem to be having uuid in the above statement highlighted in work benches query window with the statement "Error Syntax near uuid()",
I'm moving to MySQL. What's the correct implementation of this statement?
Any help/advise is much appreciated
Try to use a BEFORE INSERT trigger -
DELIMITER $$
CREATE TRIGGER trigger1
BEFORE INSERT
ON aspnet_paths
FOR EACH ROW
BEGIN
IF NEW.PathId IS NULL THEN
SET NEW.PathId = UUID();
END IF;
END
$$
DELIMITER ;
