Mysql 如何在其中制作一些触发器？

触发器1:

DELIMITER //
CREATE TRIGGER `Trigger 1` AFTER INSERT ON `Likes`
FOR EACH ROW
BEGIN 
UPDATE News SET 
`CountUpLikes` = (SELECT COUNT(*) FROM `Likes` WHERE `NewsIdn` = OLD.`NewsIdn` AND `Type` = 'up'),
`CountDownLikes` = (SELECT COUNT (*) FROM `Likes` WHERE `NewsIdn` = OLD.`NewsIdn` AND `Type` = 'down'),
`CountFavorites` = (SELECT COUNT(*) FROM `Likes` WHERE `NewsIdn` = OLD.`NewsIdn` AND `IsFavorite` = 'yes') c;
END

DELIMITER //
CREATE TRIGGER `Trigger 1` AFTER UPDATE ON `Likes`
FOR EACH ROW
BEGIN 
UPDATE News SET 
`CountUpLikes` = (SELECT COUNT(*) FROM `Likes` WHERE `NewsIdn` = OLD.`NewsIdn` AND `Type` = 'up'),
`CountDownLikes` = (SELECT COUNT (*) FROM `Likes` WHERE `NewsIdn` = OLD.`NewsIdn` AND `Type` = 'down'),
`CountFavorites` = (SELECT COUNT(*) FROM `Likes` WHERE `NewsIdn` = OLD.`NewsIdn` AND `IsFavorite` = 'yes') c;
END

触发器2:

DELIMITER //
CREATE TRIGGER `Trigger 1` AFTER INSERT ON `Likes`
FOR EACH ROW
BEGIN 
UPDATE News SET 
`CountUpLikes` = (SELECT COUNT(*) FROM `Likes` WHERE `NewsIdn` = OLD.`NewsIdn` AND `Type` = 'up'),
`CountDownLikes` = (SELECT COUNT (*) FROM `Likes` WHERE `NewsIdn` = OLD.`NewsIdn` AND `Type` = 'down'),
`CountFavorites` = (SELECT COUNT(*) FROM `Likes` WHERE `NewsIdn` = OLD.`NewsIdn` AND `IsFavorite` = 'yes') c;
END

DELIMITER //
CREATE TRIGGER `Trigger 1` AFTER UPDATE ON `Likes`
FOR EACH ROW
BEGIN 
UPDATE News SET 
`CountUpLikes` = (SELECT COUNT(*) FROM `Likes` WHERE `NewsIdn` = OLD.`NewsIdn` AND `Type` = 'up'),
`CountDownLikes` = (SELECT COUNT (*) FROM `Likes` WHERE `NewsIdn` = OLD.`NewsIdn` AND `Type` = 'down'),
`CountFavorites` = (SELECT COUNT(*) FROM `Likes` WHERE `NewsIdn` = OLD.`NewsIdn` AND `IsFavorite` = 'yes') c;
END

请告诉我如何一次触发两个触发器

例如，我能做些什么

CREATE TRIGGER `Trigger full` AFTER UPDATE OR INSERT ON `Likes`

或否？

您不能使用1个触发器来代替某些触发器。Mysql不允许在同一个触发器上发生多个事件
