Question

我在試圖創建下面的觸發器問題觸發器內：

CREATE TRIGGER loteria_loterias AFTER UPDATE ON loteria_loterias 
FOR EACH ROW BEGIN 
UPDATE 
    loteria_loterias l 
    JOIN loteria_tipos t 
    ON l.tipo = t.id 
SET 
    NEW.fecha_fin = NEW.fecha_ini + interval t.duracion hour 
WHERE c.cID=NEW.cID; 
END 

我有這個定義的表：

CREATE TABLE `loteria_loterias` (
`id` int(11) unsigned NOT NULL AUTO_INCREMENT, 
`tipo` int(11) unsigned NOT NULL, 
`fecha_ini` datetime NOT NULL, 
`fecha_fin` datetime DEFAULT NULL, 
`ganador` varchar(60) CHARACTER SET utf8 DEFAULT NULL, 
PRIMARY KEY (`id`), 
KEY `ganador` (`ganador`), 
KEY `tipo` (`tipo`), 
CONSTRAINT `loteria_loterias_ibfk_2` FOREIGN KEY (`tipo`) REFERENCES `loteria_tipos` (`id`), 
CONSTRAINT `loteria_loterias_ibfk_1` FOREIGN KEY (`ganador`) REFERENCES `tegm_users` (`user_login`) 
) ENGINE=InnoDB AUTO_INCREMENT=18 DEFAULT CHARSET=latin1 



CREATE TABLE `loteria_tipos` (
`id` int(11) unsigned NOT NULL AUTO_INCREMENT, 
`nombre` varchar(60) NOT NULL, 
`coste` int(11) NOT NULL, 
`premio` int(11) NOT NULL, 
`duracion` int(11) NOT NULL COMMENT '(en horas)', 
`activa` tinyint(1) NOT NULL, 
`x` int(11) NOT NULL COMMENT '(coordenadas del cartel)', 
`y` int(11) NOT NULL COMMENT '(coordenadas del cartel)', 
`z` int(11) NOT NULL COMMENT '(coordenadas del cartel)', 
UNIQUE KEY `id` (`id`), 
KEY `id_2` (`id`) 
) ENGINE=InnoDB AUTO_INCREMENT=5 DEFAULT CHARSET=latin1 

根據MySQL的：

#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 9

您錯過了ON關鍵字：

CREATE TRIGGER loteria_loterias AFTER UPDATE ON loteria_loterias 
              ^^
