嗨我试图用一个触发器更新两个不同的表,但我不断收到语法错误,我不确定我做错了什么
如果我只是更新一个表,1064 - 您的SQL语法出错;检查与MySQL服务器版本对应的手册,以获得正确的语法
靠近'UPDATE specialitys s
加入speciality_objects o ON s.id = o.speciality'在第2行
触发器工作正常,但我不能将它们都放在一个触发器中
这是我的触发器
DELIMITER $$
CREATE TRIGGER after_user_type_or_status_change
AFTER UPDATE
ON users
FOR EACH ROW
BEGIN
UPDATE stats s
SET
ee_counter =
CASE
WHEN NEW.type= 1 THEN ee_counter + 1
WHEN NEW.type= 3 && OLD.type = 2 THEN ee_counter + 1
WHEN OLD.type= 1 && NEW.type != 3 THEN ee_counter - 1
ELSE ee_counter
END ,
er_counter =
CASE
WHEN NEW.type= 2 THEN er_counter + 1
WHEN NEW.type= 3 && OLD.type = 1 THEN er_counter + 1
WHEN OLD.type= 2 && NEW.type != 3 THEN er_counter - 1
ELSE er_counter
END
WHERE
s.id = 1;
END $$
BEGIN
UPDATE specialitys sp
JOIN speciality_objects o
ON sp.id = o.speciality_id
JOIN users u
ON o.user_id = u.id
SET
counter =
CASE
WHEN NEW.status = 1 THEN counter + 1
ELSE counter
END
WHERE
sp.id = o.speciality_id ;
END $$
DELIMITER ;
答案 0 :(得分:0)
中间的END $$
正在结束触发器定义。删除它和以下BEGIN
