Dummy question: Have the next code in MySQL, but when run it in HeidiSQL, show a sintaxis error near '// CREATE TRIGGER'. I'm not sure if that happen because the trigger doesn't exists. This is the code:
DROP TRIGGER IF EXISTS oportunidades_movimiento_entregado //
CREATE TRIGGER oportunidades_movimiento_entregado;
AFTER INSERT ON historial_entregado
FOR EACH ROW BEGIN
UPDATE oportunidades
SET oportunidades.fechaModificado = NEW.fecha_creacion
WHERE NEW.oportunidad_id = oportunidades.id;
END//
UPDATE
DELIMITER $$
DROP TRIGGER IF EXISTS oportunidades_movimiento_entregado $$
CREATE TRIGGER oportunidades_movimiento_entregado
AFTER INSERT ON historial_entregado
FOR EACH ROW BEGIN
UPDATE oportunidades
SET oportunidades.fechaModificado = NEW.fecha_creacion
WHERE NEW.oportunidad_id = oportunidades.id;
END; $$
DELIMITER //
This works, but now my doubt is... All the code (the DROP and the CREATE) will run everytime, or just the CREATE? I need this because I'm working with 2 tables, in one of them I insert/update the data, after with a trigger insert some of the columns in another table to keep a historial, but when I make a INSERT or UPDATE query in the first table, MySQL display the error #1442
Can't update table
oportunidades
in stored/function trigger because it's already used by statement which invoked this stored function/trigger.
