sql中的错误创建触发器声明（mysql） [英] error in sql create trigger statment(mysql)

问题描述

DROP TRIGGER IF EXISTS `insert_points` ; CREATE TRIGGER `insert_points` BEFORE INSERT ON `p_players` FOR EACH ROW BEGIN SET NEW.total_points = NEW.gold_num + NEW.total_people_count + NEW.week_thief_points +NEW.week_dev_points +NEW.week_defense_points+NEW.week_attack_points+NEW.defense_points+NEW.attack_points+NEW.hero_points+NEW.villages_count; END;

当我尝试创建触发器时它会给我错误

when i try to create that trigger it gives me that error

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 'CREATE TRIGGER `insert_points` BEFORE INSERT ON `p_players` FOR EACH ROW BEGIN ' at line 2

i使用mysql

i use mysql

推荐答案

我在Trigger中看到语法问题。正确的方法应该是

I am seeing syntax problems in your Trigger. The correct way should be like

DROP TRIGGER IF EXISTS insert_points;


CREATE TRIGGER insert_points
BEFORE INSERT
  ON p_players
  FOR EACH ROW 
BEGIN 

   SET NEW.total_points = NEW.gold_num + NEW.total_people_count + NEW.week_thief_points +NEW.week_dev_points+NEW.week_defense_points+NEW.week_attack_points+NEW.defense_points+NEW.attack_points+NEW.hero_points+NEW.villages_count;

END;
