Re: Concatenar Campos con un Triggers

Hola Ivan,

El problema es que no puedes actualizar la misma tabla que activo el disparador (trigger), en este caso `clientes`, por ello el mensaje de error, revisa B.5.9: Can triggers access tables?

Una alternativa es aplicar la concatenaci├│n en el "BEFORE INSERT" del trigger de la siguiente manera:

/* Trigger structure for table `clientes` */

DELIMITER $$

/*!50003 DROP TRIGGER*//*!50032 IF EXISTS */ /*!50003 `combinarNombres` */$$

/*!50003 CREATE TRIGGER `combinarNombres` BEFORE INSERT ON `clientes`
FOR EACH ROW
BEGIN
	set new.`nomCompleto` = concat(new.`nbrClientes`, space(1) , new.`apeClientes`);
END */$$

DELIMITER ;

Espero te sea ├║til.
